Water Pipeline Work Resumes at Sawyer Camp Trail

2012-01-24T13:46:00.000-08:00

Beginning this week, culverts and streams near Sawyer Camp Trail will fill with water running into the reservoirs…but much of the water is not from the recent heavy rain. Our water department staff will be emptying the pipeline that runs adjacent to Sawyer Camp Trail from January 24 through January 30 to allow for seismic upgrade work. Increased truck traffic will be present on the trail.

Once empty, crews will use a cement mortar lining to strengthen the existing pipeline. Construction activity will be visible along Sawyer Camp Trail at numerous spots from the .5 to 3 mile markers.

Near the San Andreas Dam on the 5 mile marker of Sawyer Camp Trail (the southern end of San Andreas Lake) water trucks will draw water from the reservoir to service the nearby golf course. The trucks will need to cross the trail in that location a few times each day, during periods of dry weather only. Cyclists heading down the hill from the northern trailhead should use caution!

The trail remains open during construction from sunrise to sunset. Please subscribe (see right) to receive automatic email updates about closures.

Please contact us with any questions or concerns at (866) 973-1476.

Seismic Upgrades to Water System Resume at Sawyer Camp Trail

2012-01-13T13:53:00.000-08:00

Work to prepare the trail for rain is underway at several locations along the southern-most 3-mile section. This Saturday two hydroseed trucks will seed hillsides along the trail. The trucks will primarily use water system access roads that run behind the trail. The hydroseed trucks must drive on Sawyer Camp Trail between the 2.3 and 3 mile markers and will be supervised by an environmental specialist at all times.

Next week, construction work to seismically upgrade the water pipeline adjacent to the trail resumes.

Increased truck traffic will be present on the trail Tuesday to Friday (January 17^th to 20^th). The trail will remain open sunrise to sunset. No trail closures are now scheduled, but we do expect short closures this winter. Please subscribe (see right) to receive automatic email updates.

Before sunrise, our contractor will be moving large equipment down the trail to pipeline work locations. Please do not enter the trail before sunrise! You will be entering an active construction zone.

Construction is taking place near the popular southern-most 3-mile section of the trail. If you haven’t discovered the northern section of the trail yet, now is a great time! The northern trailhead is in Millbrae and can be reached from I-280 via the Larkspur/Hillcrest Blvd. exit (southbound on 280) or via the Millbrae Ave. exit (northbound on 280). Turn west on Hillcrest Blvd. to the trail entrance.

Please contact us 24 hours a day at (866) 973-1476 if you have any questions or concerns about activity near Sawyer Camp Trail.

Critical Water System Work in January 2012

2012-01-06T15:34:00.000-08:00

Neighbors of San Andreas Lake, just west of Highway 280 near the town of San Bruno, may have noticed the Lake’s recent low water level. This reservoir is low due to Water System Improvement Program work – not due to recent dry weather. Despite the lack of rain so far this winter, our region’s reservoirs are still in good shape thanks to heavy rain last year. The water level is expected to remain low in San Andreas Lake until our water pipeline is returned to service in late March 2012.

Also:

Underwater construction at San Andreas Lake is part of the Crystal Springs/San Andreas Transmission System Upgrade project. This project currently has several work locations throughout the 23-acre Peninsula Watershed. On Monday morning, January 9^th three sequential deliveries of large pipe will take place from 7 a.m. to 9 a.m. on Crystal Springs Road in San Bruno just north of the Junipero Serra County Park and San Bruno City Park. Please call our 24-hour phone line if you have any concerns or questions!

Further south near Sawyer Camp Trail, crews will begin mobilizing equipment after the Martin Luther King holiday weekend in preparation for a “shutdown” of the water pipeline that runs next to the trail. Sawyer Camp Trail is expected to be open every day, sunrise to sunset, until the week of January 17^th. We do expect a short trail closure that week or in late January. Please subscribe (see right) to receive an automatic email notification as soon as the exact closure dates are announced.

Sawyer Camp Trail: December Update

2011-12-23T13:04:00.000-08:00

We’ve got some beautiful winter weather ahead on Sawyer Camp Trail! Major construction work next to the trail has wrapped up until late January. Vehicles on the trail have become a rare sight this month!

The trail is now open every day from sunrise to sunset. Some work may occur in early January to prepare for winter storms and this may require short trail closures, however we don’t expect any lengthy disruptions.

In late January, a portion of the water pipeline that runs adjacent to the trail will be “shut down” and emptied of water to allow for seismic upgrades. The trail will need to be closed for 2 or 3 days in order to stage equipment needed for these important water system improvements.

Some construction work will take place in the Peninsula Watershed during the week between Christmas and New Year’s. The drill rig that is set up on the shoulder on Crystal Springs Road near Polhemus will be present through the end of the December. A small crew is working on the existing water pipeline.

In the Lower Crystal Springs Reservoir, demolition of the Crystal Springs outlet tower (see photo) continues next week and into January. This work is part of the seismic upgrade of the transmission system that carries water from the reservoir to the Harry Tracy Water Treatment Plant in Millbrae.

Please subscribe (see right) for automatic email updates about 2012 Sawyer Camp Trail closures. We can be reached 24-hours a day at (866) 973-1476 if you have any questions or concerns. Happy Holidays!

We do expect additional closure days in December. If you have not already done so, subscribe for updates by entering your email to the right-hand side of this website.

Near San Andreas Trail, PG&E has finished water-testing their gas pipelines and is continuing to clean up the area next to the northern-most end of San Andreas Trail. This PG&E work is a separate project from the continuing marine construction in San Andreas Lake (scroll down to read story from November 18, 2011).

The lane closure on Crystal Springs Road near Polhemus has been postponed until early January. Stay tuned for more information about upcoming work near that intersection.

Please call us 24 hours with any questions at (866) 973-1476!

Sawyer Camp Trail 3-Day Closure – November 30 to December 2

2011-11-28T10:48:00.001-08:00

Sawyer Camp Trail will be closed this week on November 30, December 1 and December 2 (Wednesday through Friday).

The closure is necessary as construction crews continue seismic upgrades to our Crystal Springs/San Andreas water pipeline. Work also continues to prepare for winter rains and to complete new access road segments. The new access road segments will allow maintenance crews to reach the pipeline with minimal disturbance to recreational users of Sawyer Camp Trail.

Please call us 24 hours a day with any questions or concerns!

Underwater Construction Continues in the Peninsula Watershed

2011-11-18T15:06:00.001-08:00

San Andreas Lake, the reservoir just west of the City of San Bruno, is the site of a large regional water improvement project, however construction work is taking place beneath the surface of the water. Demolition of a 1930’s-era water transmission tunnel is in progress 40 feet underwater!

Divers are razing this structure underwater, yet one would never know walking around the lake. From the shore of San Andreas Lake, the only sound one can hear is the diver’s air compressor and support equipment. The tunnel will be replaced with a new underwater intake structure in 2012 that will send water from the reservoir to the Harry Tracy Water Treatment Plant for distribution to our taps.

In addition to the divers, hikers on San Andreas Trail may see boats and yellow booms in the water connected to this construction. The yellow booms are called silt curtains: underwater “curtains” that protect water quality and keep species out of the work zone.

PG&E is also doing major work this autumn near the San Andreas Trail – water testing the gas pipelines. The PG&E work is an unrelated project and is expected to wrap up by Thanksgiving in this location.

At the Lower Crystal Springs Reservoir work site, next to the southern trailhead to Sawyer Camp Trail, divers are working nearly 100 feet beneath the water’s surface. To work at that depth, seven divers are required for one day’s work. Each diver may spend 45 minutes underwater before resurfacing. Currently, the team is installing supports for new valves.

Marine construction in both reservoirs continues through 2013 as part of the Crystal Springs/San Andreas Transmission System Upgrade project. Please call us 24 hours at (866) 973-1476 with any questions.

Sawyer Camp Trail 2-day Closure – November 16th and 17th

2011-11-11T10:31:00.001-08:00

Sawyer Camp Trail will be closed for two days on November 16^th and 17^th (Wednesday and Thursday). The entire trail will close those two days, to reopen at sunrise on Friday morning.

During the closure, our project team will deliver additional rock to new access road segments and continue seismic upgrades on our Crystal Springs/San Andreas Pipeline. The closure is also necessary to prepare for winter storms at construction sites near the trail.

Please contact us 24-hours a day with any questions or concerns!

Crystal Springs Reservoir Projects Update

2011-11-04T09:00:00.000-07:00

Sawyer Camp Trail reopened today at sunrise after a 2-day closure. More short trail closures are likely this season…please stay tuned!

San Andreas Trail to the north remains open…but PG&E gas pipeline water-test work (including 50 blue “tanks” that hold discharged water) will continue adjacent to the northern-most tip of San Andreas Trail through November.

This weekend, work on the parapet wall and stilling basin of the Lower Crystal Springs Dam will continue all day Saturday and Sunday. Saturday, about 25 cement trucks will deliver concrete to the upper and lower dam areas from 6 a.m. to 2 p.m. The trucks will travel through the intersection of Crystal Springs Road and Skyline Blvd., so please use caution and expect some traffic delays near the southern trailhead to Sawyer Camp Trail.

Next week on November 7^th (Monday) and November 10^th (Thursday), the final large-scale concrete pours will take place at the Lower Crystal Springs Dam. Both days, 50 concrete trucks will arrive during the hours of 6 a.m. and 9 p.m. Truck traffic to the dam will continue until Thanksgiving, but at a much smaller volume.

Some construction vehicles will need to drive on Sawyer Camp Trail this Saturday, as work continues on our Crystal Springs/San Andreas Pipeline. This Sunday the trail will be construction-free! Please call us 24 hours a day with any concerns at (866) 973-1476.

Sawyer Camp Trail 2-day Closure - November 2nd and 3rd

2011-10-27T15:49:00.000-07:00

Sawyer Camp Trail will be closed for two days on November 2^nd and 3^rd (Wednesday and Thursday).

During the closure, our project team will deliver additional rock to our new access road segments, and continue seismic upgrades on our Crystal Springs/San Andreas Pipeline. Water in this pipeline has been “turned off” for the months of October and November to facilitate this work.

Notice the unusual green color on some slopes along the trail? This is a temporary, first step of re-vegetation. This bright green soil stabilizer will turn brown and blend in with the surrounding landscape as it dries. During next year’s dry season, we’ll be re-planting native plants in these locations.

One more thing of interest to trail users: the Lower Crystal Springs Dam concrete pours will continue through mid-November. The biggest day will be on Tuesday, November 1^st when approximately 65 trucks will deliver cement using Skyline Blvd., Crystal Springs Road and Polhemus Road. Much smaller pours (just a few trucks) are expected on October 28^th (Friday) and October 31^st (Monday).

2011-10-25T11:39:00.000-07:00

The entire Sawyer Camp Trail is now open! You will see some construction vehicles driving on the trail daily for the next several weeks. The largest truck is expected to be a water truck, necessary to control dust at the pipeline work locations next to the trail.

Additional short trail closures are expected this fall. Please subscribe to this website (see right) to get automatic email updates!

Neighbors have asked us about the night work currently taking place on Highway 280 above the Lower Crystal Springs Dam. This is a Caltrans project to improve drainage on the freeway. Caltrans expects the work to be completed by November 15^th, prior to the official start of the rainy season.

Please call us 24 hours a day with any questions or concerns!

Busy Day -- Work Near Sawyer Camp Trail on Monday, October 24th

2011-10-21T15:20:00.000-07:00

On Monday, October 24^th Sawyer Camp Trail will be closed from the Hillcrest Gate to the 5 mile marker. This northern-most one mile section of trail will close all day for routine water system maintenance. You will be able to enter the trail at the southern trailhead (Skyline and Crystal Springs Road) and enjoy the first five miles of trail, but there will be no through access at Hillcrest.

The southern portion of the trail will be open Monday, but hikers may see something unexpected: A Hydroseed Truck on the trail! The truck will be applying “Earth Guard” onto the slopes near the trail to prevent erosion. Earth Guard is an environmentally friendly soil stabilizer, and the work is monitored by wildlife biologists. This must be done in advance of the winter storms, but does not require the trail to be closed.

The next big concrete pour for the Lower Crystal Springs Dam stilling basin will take place this Monday, October 24^th. 90 trucks will deliver cement to the area between 6 a.m. and 8 p.m. using Polhemus and Crystal Springs Road. A smaller pour is scheduled for Tuesday, October 25^th with about 20 to 45 cement deliveries starting at 6 a.m. Construction on the Lower Crystal Springs Dam stilling basin, spillway and parapet wall is expected to finish on schedule by November 15^th!

Heavy rain this week also postponed a necessary 2-day closure of Sawyer Camp Trail. A trail closure is anticipated the third week of October…stay tuned for the exact dates!

Underwater seismic construction in Lower Crystal Springs Reservoir near the southern trailhead to Sawyer Camp Trail is progressing rapidly. Hikers on Sawyer Camp Trail will see more boats and other equipment in the water this week.

Everything that enters the water is carefully cleaned under the supervision of marine engineers and wildlife biologists. Protecting water quality and native species is top priority to the project team! The yellow floating booms in the water are silt curtains – an underwater curtain that keeps species out of the work zone and sediment inside. Similar underwater work continues in San Andreas Lake, west of the town of San Bruno.

Near the northern trailhead of the San Andreas Trail, you may also notice PG&E gas-line testing work currently underway (scroll down to see story and photo from August 24, 2011).

Sawyer Camp Trail: Construction Update

2011-09-09T11:44:00.000-07:00

Thank you to the regular users of Sawyer Camp Trail for bearing with our construction and necessary truck traffic on the trail! Truck traffic is expected to reach a peak this September and October – so remain cautious as you travel the southern portion of the trail. Our drivers are required to travel no more than 5 miles per hour – but sometimes even that pace can make for a surprise on the trail. If you see any activity that concerns you, please call our 24-hour answering line: (866) 973-1476. A good alternate: The northern portion of the trail from Hillcrest Gate is truck free!

In early October, our water pipeline adjacent to the trail will be “shut down” so that crews can install new valves. This pipeline project involves seismic upgrades to 150 connection points and replacing more than 2,000 feet of pipe.

Short trail closures are expected this autumn, but our team is making every effort to minimize inconvenience to trail users.

The good news?

Sundays are currently free of construction-related driving (Park Rangers and Watershed Keepers do still patrol the trail, as always).

Work along the northern half of the trail is now complete. Our crews will no longer be driving from the 3 mile marker to the Hillcrest Gate.

By next spring, new dedicated access road segments will allow more than 80% of the water pipeline to be reached without driving on Sawyer Camp Trail. Construction traffic on the trail is expected to be rare after January 2012.

Red-shouldered Hawks Leave the Nest

2011-08-11T14:01:00.000-07:00

In spring 2011, our construction team encountered a new friend in the trees near San Andreas Lake…a nesting red-shouldered hawk! To protect the large bird and her nest, the team gave the hawk a wide buffer zone and carefully phased in work under the full-time supervision of a wildlife biologist.

Four fledgling hawks successfully left the nest in late June and are thriving in the town of Millbrae (photo above).

The ongoing construction in the Peninsula Watershed is monitored by biologists and environmental experts. If you have any questions about the Water System Improvement Program, please call us 24-hours a day at (866) 973-1476.

Coming Soon: Underwater Work

2011-06-09T09:02:00.000-07:00

Do you have questions about work in the water at Crystal Springs and San Andreas reservoirs?

You may have seen the bright yellow booms currently prominent in San Andreas Lake and the Lower Crystal Springs Reservoir, north of Highway 92 just off Highway 280. The booms are silt curtains which block animals and plants from entering the work zones and protect water quality by containing disturbed sediment. Sawyer Camp Trail users will see silt curtains near the southern trailhead this summer.

Silt Curtains in San Andreas Lake near San Bruno; May 12, 2011

Divers will perform underwater seismic upgrades at depths of over 100 feet, and boats will continue to be a frequent sight. All watercraft and materials are carefully screened to prevent non-native species and contaminants from entering the water.

Wildlife Protection Measures for the Crystal Springs Reservoir Projects

2011-05-31T15:55:00.000-07:00

Ever wonder about the short construction fencing that has popped up around the Sawyer Camp Trail area? The black fabric fencing is only 42 inches high, but what you can’t see is it extends 6 inches below the ground! This is to prevent sensitive or endangered species from entering construction zones. This wildlife exclusion fence is monitored by onsite biologists and maintained by the project team. You can easily jump over the fence…but please don’t! You would be entering an active construction site.

Wildlife exclusion fence prevents species from entering work zone.

You may also have seen a new gravel access road on Skyline Blvd. just south of Black Mountain Road (above Lower Crystal Springs Reservoir). This is a new access road which allows our construction team and water department staff to reach our pipeline directly (rather than use Sawyer Camp Trail!). You may see a few more of these roads in the watershed in the coming months.

Hikers may also see some tree-cutting taking place near Sawyer Camp Trail this spring and summer. This is the start of the work that will seismically upgrade our 7 mile pipeline. The tree-cutting process is carefully monitored and supervised by biologists. Restoration plans require replacement trees to be planted -- in some cases three new trees will be planted in the Peninsula Watershed for every one tree cut!

Construction Update at Peninsula Watershed Reservoirs

2011-05-23T15:55:00.000-07:00

Silt curtains to protect species and water quality

delivered to San Andreas Lake: May 10, 2011

Barge and Dive Boat Launching at San Andreas Lake:

Does the water level appear low to you at San Andreas Lake? It will continue to get slightly lower to accommodate upcoming underwater seismic improvements. You may also see our crew transporting large marine equipment near the trailhead to San Andreas Trail and the northern entrance to the Sawyer Camp Trail.

The construction team must use the Hillcrest Gate entrance for water craft and other large equipment, which may cause delays on Hillcrest Blvd. (near Skyline in Millbrae, just west of 280). Large deliveries are expected over the next couple of weeks, with work in the reservoir taking place all summer.

If you frequently access Sawyer Camp Trail from Millbrae’s northern trailhead, the trail will remain open! Follow us on Twitter for real-time updates about activities: http://www.twitter.com/sawyercamptrail.

Saving the Rare Red-Legged Frog

2011-05-13T15:28:00.000-07:00

Thousands of young California red-legged frog tadpoles now have better odds for making it to metamorphosis and adult life in a marshy new home along the Lower Crystal Springs Reservoir. While still in the egg stage, they were relocated from the Lower Crystal Springs Dam construction site by wildlife biologists in preparation for work to raise the dam’s parapet wall.

A concrete pit atop the dam filled with rainwater created a hospitable habitat for the rare and federally protected amphibian. By March 2011, the pond had seven egg masses attached to floating plant stems, and five adult frogs. The team also saved approximately 200 Pacific tree frogs and 100 rough-skinned newts from shallow ponds on the Lower Crystal Springs Dam construction site.

Red-Legged Frog relocated from construction site in spring 2011.

Peninsula Watershed Construction Update

2011-05-05T13:59:00.000-07:00

Both Sawyer Camp Trail and San Andreas Trail remain open…and spring weather is finally here!

Neighbors and hikers in the area of San Andreas Lake may see work throughout the spring and summer along the shore. The ongoing installation of silt curtains into the reservoir protects water quality and keeps fish and other species out of the work zone. Divers will perform seismic upgrades at depths of over 100 feet. These upgrades enhance our ability to transmit raw water from San Andreas Lake to the nearby Harry Tracy Water Treatment Plant.

Pulgas Water Temple Temporary Closure

2011-04-21T16:03:00.000-07:00

The Pulgas Water Temple will be closed for several weeks beginning on Monday, April 25, 2011. The temporary closure enables critical water system work to take place in the entrance and parking lot areas. Reopening is expected in late summer 2011.

The Pulgas Water Temple and the associated facilities around it serve the Hetch Hetchy Regional Water System and are components of the Crystal Springs Reservoir System. The Crystal Springs Reservoir System provides supplementary water supply to San Mateo and San Francisco counties, and is the primary emergency water source should delivery from the Hetch Hetchy aqueduct be interrupted.

The work is part of the Water System Improvement Program to repair, replace and seismically upgrade the Hetch Hetchy Regional Water System.

Please contact us with any questions or concerns at (866) 973-1476, 24 hours a day. For email notification when then Pulgas Water Temple reopens, subscribe to this blog!

Construction Crews Prepare for a Busy Spring Near Sawyer Camp Trail

2011-04-20T15:51:00.000-07:00

A new sight you can expect in late April is a large crane along the shoreline of the Lower Crystal Springs Reservoir near the southern end of Sawyer Camp Trail. Don’t worry, the large equipment is only here temporarily -- and when the project is complete there will be permanent improvements to the great view pictured below.

Lower Crystal Springs Dam after removal of the bridge, January 2011.

Work on the Lower Crystal Springs Dam project is moving forward rapidly, especially as we enter the dry season. Crews may work some nights and weekends in the area in order to complete major construction before the rainy season begins next winter.

Many trail users last month noticed our team recording a video along Sawyer Camp Trail. The pre-construction survey is finished, and you may see additional tree cutting along the trail in the coming weeks. This work is supervised by biologists and is a carefully monitored process.

Sawyer Camp Trail remains open, and will be closed only for short intervals during construction. Subscribe to this blog for updates.

Peninsula Region Construction Launch Event Celebrates 4 Major Projects

2011-04-01T10:56:00.000-07:00

Last Wednesday at the Lower Crystal Springs Reservoir, the San Francisco Public Utilities Commission (SFPUC), San Mateo County Board President Carole Groom, the Bay Area Water Supply and Conservation Agency and officials from throughout San Mateo County gathered to launch another $320 million in upgrades for the Hetch Hetchy Regional Water System. Together these improvements will allow the SFPUC to provide water service to over 1 million people in San Mateo County and San Francisco within 36-hours of a major earthquake.

The event was held on the water’s edge adjacent to the two outlet towers that draw water out of the Crystal Springs Reservoirs. These historic structures built in 1891 and 1936 by Spring Valley Water Company are scheduled to be demolished and submerged under the water line as part of the upgrades. Work at these structures and in the reservoirs represents the most extensive underwater work in the Water System Improvement Program. Additional work in the area includes upgrades to the spillway and parapet wall at the top of the Lower Crystal Springs Dam. Built in 1890, this concrete, gravity-arch dam later served as a model for the Hoover Dam.

“San Mateo County residents and businesses depend on this regional water system. It has taken years of planning and collaboration by many agencies to reach this point,” said Carole Groom, President of the San Mateo County Board of Supervisors. “There will definitely be some inconvenience due to construction, but this inconvenience pales in comparison to not having access to clean drinking water.”

The projects celebrated include upgrades to the Harry Tracy Water Treatment Plant (www.sfwater.org/peninsula), Crystal Springs Pipeline No. 2 (www.sfwater.org/cspl2), Lower Crystal Springs Dam and Crystal Springs/San Andreas Transmission System (www.sfwater.org/sct and www.Twitter.com/SawyerCampTrail).

Stormy Weather Necessitates Swing Shift in Crystal Springs Reservoir Area

2011-03-18T18:16:00.000-07:00

Night work will be ongoing adjacent to the Sawyer Camp Trail area -- from 3 p.m. to 11 p.m., Monday through Saturday –- as the project team makes up time due to rain delays and the relocation of a sensitive species (an unexpected neighbor…bats!) As most construction area noise is below the decibel level of nearby Highway 280, recreational users of the area are unlikely to notice the change in work hours.

If you live in the gorgeous hills above the Lower Crystal Springs Dam, you may see additional night-time illumination below Highway 280. The work crew has taken extra care to ensure these lights point downward, rather than in your direction!

Please do not hesitate to contact us with any questions or comments at (866) 973-1476, 24 hours a day.

Update: Work Begins at San Andreas Lake and Continues at Sawyer Camp Trail

2011-03-02T13:44:00.000-08:00

Is the San Andreas Trail one of your regular hiking spots? If so, you may see workers near San Andreas Lake preparing for construction with fencing and some tree cutting. Both are necessary steps to protect the environment as construction starts. San Andreas Trail will remain open for everyone throughout construction.

Not far from the southern entrance to Sawyer Camp Trail, crews are installing support columns for the foundation of the new Crystal Springs Pump Station. Noise should be minimal, but ground vibrations may be felt near the trailhead (Monday to Saturday, 7 a.m. to 5 p.m., ongoing to mid-March).

Please Be Aware: Parking may become more limited near the Sawyer Camp Trailhead, as construction activity increases. The project team realizes that parking is already difficult at Sawyer Camp Trail, and will make every effort to preserve access. Stay tuned for more details!

Crystal Springs Reservoir area, 1960

Construction is here!

2011-01-21T19:39:00.000-08:00

Construction fence installation and tree removal have started near the Sawyer Camp Trailhead.

The extensive construction fencing you see ensures animals and visitors stay clear of our active construction areas. In addition, tree removal is a necessary step to clear the land before we can work on the pipeline. Don’t worry - tree removal is a carefully monitored process – ensuring appropriate access for construction without negative impacts to the natural environment.

Also, last week – Boat Sighting on the Reservoir!

If you walked Sawyer Camp Trail last week, perhaps you glimpsed a rare sight: a boat on the reservoir! On January 13th and 14th, a dive team began inspecting the Dam’s underwater outlet structures – about 100 feet below the surface. Soon this sight will become more common as divers perform seismic upgrades to these underwater outlet systems. Work will take place in all three reservoirs (Upper and Lower Crystal Springs, and San Andreas Lake).
