If you live in the San Francisco Bay Area and have been hoping to see the film The Longest Straw but can’t make it to tomorrow’s screening here in Lee Vining, you’re in luck…

On Wednesday, August 8 at 6:00pm the Bay Institute will be hosting a screening at the Aquarium of the Bay! Film director and star Samantha Bode will be there, along with the Mono Lake Committee’s Information & Restoration Specialist Greg Reis, for a Q&A and discussion after the film. Tickets cost $15 and include access to the Aquarium, a reception with light refreshments, and the screening. For more information or to purchase tickets click here.

Save the tufa!

Tufa is otherworldly, oddly enchanting, and one of Mono Lake’s most iconic and popular features. Tufa towers are important nesting sites for birds—from Osprey to owls—while underwater tufa is habitat for alkali flies. For years, photographs of tufa have played an important role in spreading the message that Mono Lake, and the tufa itself, needs protecting.

Fragile rock

Growing only underwater, tufa is a precipitate formed when calcium-rich spring water mixes with carbonate-rich Mono Lake water—slowly building up around seeps and springs. Though tufa towers are rock formations, they are fragile—they crumble, topple, and erode from wave action, high desert weather, and, unfortunately, from people being careless around them. (more…)

Evidence of high flows persists on Mill Creek: Restoration potential reaffirmed

Almost a year after the epic 2017 winter and resulting record Mono Basin runoff, positive effects from the high flows can still be seen on all of Mono Lake’s tributary streams—including, notably, the beleaguered floodplain of the Mill Creek bottomlands.

During last year’s record runoff, long-dry side channels in the Mill Creek bottomlands carried water; some of the rewatered channels were still flowing this spring. Photo by Elin Ljung.

Last summer, long-dry side channels in the bottomlands carried water when Lundy Lake Reservoir spilled for almost the entire summer. Some of these rewatered channels are still flowing despite low-flow early springtime conditions, and evidence of lasting restoration benefits is abundant. Back eddies and ponded areas well away from flowing channels continue to hold water. Below the surface, recharged groundwater is once again available for vegetation, and fine sediment deposited across floodplain cobble is primed for new seedlings to grow. All of this is a glimpse into Mill Creek’s bright future. (more…)

Aqueduct retrofit ensures export accuracy: Mono Lake Committee advocacy produces results

One thing the Mono Lake Committee and the Los Angeles Department of Water & Power (DWP) can agree on is that accurate measurement of water exported from the Mono Basin is important. One might assume that measuring water sent out of the Mono Basin through the Los Angeles Aqueduct would be fairly straightforward, but due to infrastructure complexities, DWP has historically used a calculation to derive the export amount.

Aqueduct improvements in 2009, shown here, added equipment to directly measure water exports, but the system was unreliable until recent repairs, thanks to the Committee’s persistence. Photo by Greg Reis.

Getting from calculation to measurement

To understand why DWP couldn’t simply measure its (more…)

The future of Sierra Nevada snow: Dr. Alex Hall on the climate future of the Sierra

What will happen to the Sierra Nevada’s snowpack as climate change impacts accumulate through the 21st century? This question is vital to both the ecological health of the Range of Light and to water delivery systems throughout California. And, it matters a great deal to Mono Lake and its many miles of tributary streams, which depend on Sierra runoff for their vitality.

Forecasts of the future rely on complex climate modeling, and I talked with Dr. Alex Hall, Professor of Atmospheric & Oceanic Sciences at UCLA, about the work he and his team have been conducting to produce actionable climate science. Dr. Hall heads the Center for Climate Science, where they have developed cutting-edge downscaling techniques to create geographically detailed climate projections for the Los Angeles area and the Sierra Nevada.

Geoff: Thanks for taking time to talk, Alex. You have just released a major report, Climate Change in the Sierra Nevada: California’s Water Future. What are the big takeaway messages?

Alex: Temperatures across the Sierra Nevada are warming (more…)

Screenings of “The Longest Straw” film at Mono Lake

In 2015 we had the pleasure of meeting Samantha Bode. She had just finished hiking the length of the Los Angeles Aqueduct—338 miles from Los Angeles to Mono Lake—for a documentary she was making.

In Sam’s documentary, The Longest Straw, she talks to community leaders, residents, and advocates in Los Angeles as well as the communities most affected by the exportation of water south. The film premiered at the New Urbanism Film Festival last October and we are excited to be hosting three showings here in the Mono Basin this summer.

Free screenings will be held on June 22, July 6, and July 20 at 7:00pm at the (more…)

Mill Creek return ditch passes test: Possible solution to returning diverted water back to the creek

In an effort to explore ways to return water to Mill Creek and therefore satisfy its legal obligations, Southern California Edison (SCE) released water from the Lundy hydroelectric plant into the Mill Creek return ditch last September, successfully returning water to the creek (see Fall 2017 Mono Lake Newsletter). The return ditch has been part of the hydropower system for a century. SCE was motivated to do this flow test because of the languishing problem of how to comply with Mill Creek water rights.

The Mill Creek return ditch carried flows of up to 16 cubic feet per second during a 61-day test last fall, returning water to the creek consistent with long-established water rights. Photo by Elin Ljung.

Prior to releasing water into the ditch, SCE evaluated the system and did routine maintenance to stabilize the earthen banks. SCE staff were on site during (more…)

Diverse watchdog duties keep the Mono Lake Committee busy

The Mono Lake Committee is serious about protecting and restoring Mono Lake, its tributary streams, and surrounding lands. That means being on constant alert as a watchdog, and recent months have provided some interesting examples of what that requires.

Sometimes the Committee chases issues that have lengthy histories and require continuous pressure to move toward resolution—the 2013 Stream Restoration Agreement with the Los Angeles Department of Water & Power (DWP) is one example. Years of work (more…)

Each year printed copies of the Mono Lake Committee Annual Report are sent out to Defense Trust level members and Guardians of the Lake monthly-giving club members, but it is has information that is important to members at all giving levels, friends, anyone who is curious, and the general public. So without further ado, click here to see the Mono Lake Committee 2017 Annual Report.

Did you get a yearbook in high school? The Annual Report feels a little bit like the grown-up version of getting the yearbook … (more…)

April 1 Mono Lake level: 6378.3 feet above sea level and rising

April 1, the beginning of the runoff year, is a particularly important day for Mono Lake. Each April 1 Mono Lake Committee and Los Angeles Department of Water & Power (DWP) staff walk down to Mono Lake and read the lake level, together. It is particularly important because it is the April 1 lake level that determines how much water is allowed to be diverted from Mono Basin streams to the City of Los Angeles for the year.

The first time I participated in one of these April 1 lake level readings was in 2015 when the lake had dropped to a level that triggered a 70% reduction of water exports. The second time, the lake narrowly cleared the level that would have halted water exports altogether. Years of drought lowered the lake and heightened concern over available exports, but this year was different. This year Mono Lake is on the rise. (more…)
