April reading of Mono Lake’s level with DWP

Tuesday, April 2nd, 2019 by Elin, Communications Coordinator

As is tradition in early April, this morning staff from the Mono Lake Committee and the Los Angeles Department of Water & Power (DWP) met at Mono Lake’s shore to read the lake level gauge at the start of this new runoff year.

The lake’s surface was a bit unsettled due to a spring rainstorm passing through, but Maureen (Committee) and Jason (DWP) watched the fluctuations carefully and settled on an official lake level reading of 6382.07 feet above sea level. (more…)

How much is Mono Lake going to rise or fall this year?

Wednesday, March 20th, 2019 by Arya, Communications Director

It’s that time of year again, when all eyes are on the Sierra snowpack, the level of Mono Lake, and spreadsheets.

Just imagining this winter’s snowpack flowing down Mono Basin streams this spring brings a gleeful sigh of relief. But … spreadsheets? Yep, because spreadsheets, forecast models, experts, and in-depth Mono Basin hydrologic knowledge, when carefully woven together, are how we figure out the big question for Mono Lake: how much is the lake going to rise or fall this year?

Monitoring Mono Lake’s level by ski

Friday, March 8th, 2019 by Maureen, Membership Assistant

In a winter full of snow, getting down to the lake has been a bit more challenging and a lot more fun.

The Mono Lake Committee monitors Mono Lake’s level throughout the year, at least once a month and usually more frequently. You can find monthly lake levels going back to 1971 here. The most important lake level reading of the year happens on (more…)

Official April 1 Mono Lake level: 6381.86 feet

Monday, April 2nd, 2018 by Arya, Communications Director

Technically, we did it on March 31, but for all intents and purposes, it’s the April 1 official joint reading of Mono Lake’s level with Mono Lake Committee and Los Angeles Department of Water & Power (DWP) staff together. This reading on this day is particularly important because the number recorded translates into how much water DWP is allowed to divert from Mono Basin streams over the course of the coming year.

Timelapse video: Watch Mono Lake rise before your eyes

Friday, October 13th, 2017 by Andrew, Digital Engagement Coordinator

So far in 2017, Mono Lake has risen an astounding 4.5 vertical feet before leveling off in the past month. About 3 feet of that total lake rise occurred from mid-May to mid-August. Watch below for a quick 20-second timelapse showing the incredible lake rise this summer, or scroll down and see the full two-and-half-minute timelapse video.

Mono Lake’s California Gulls safe for the season

Thursday, May 25th, 2017 by Geoff, Executive Director

A mile of citizen-funded solar-powered electric fence is up and running, protecting Mono Lake’s nesting gulls—one of the three largest colonies in the world—from mainland predators. The fence is the result of a year and a half of planning by the Mono Lake Committee and California State Parks along with other agency partners, a dedicated local installation team, and generous funding from Mono Lake supporters across the country.

The temporary electric fence stretching one mile across the landbridge has 11 motion-activated wildlife cameras with infrared nighttime flash capability along its length. In late April, camera #5 documented a coyote walking the fence line, confirming that the fence is functioning as a coyote barrier. Mono Lake Committee wildlife camera photo.

Why is the temporary fence—which will be removed when nesting is finished—needed? Five years of drought lowered Mono Lake seven feet, shrinking the protective moat of water between the lake’s north shore and Negit Island and adjacent islets—exposing a landbridge that allows coyotes access to the lake’s long-established nesting colony of California Gulls. Last summer signs were found on a few of these islets that coyotes had indeed walked the landbridge and then swum the remaining 500 feet or so of shallow water to prey on eggs and chicks, disrupting nesting and causing gulls to be suspicious of returning to these sites in future years.

Fence post: An update from Mono Lake’s landbridge

Friday, April 21st, 2017 by Elin, Communications Coordinator

The temporary electrified fence protecting Mono Lake’s nesting California Gulls has been up and running for about three weeks now. After a long and snowy winter the gulls’ calls signal spring’s arrival, and it’s gratifying to know that as they build nests and lay eggs out on the islands, they are protected from coyote predation.

The fence stretches for about one mile across the landbridge, and is made up of five sections that overlap—an electrified long middle section, two shorter electrified sections at the ends near the water’s edge, and two passive sections at (more…)

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

Monday, April 10th, 2017 by Robbie, Restoration Field Technician

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…)

A skiing adventure to check Mono Lake’s level

Tuesday, January 24th, 2017 by Robbie, Restoration Field Technician

This January is proving to be the wettest January in our weather recording history. In Lee Vining, we saw 5.5 inches of snow on January 4, and we received a combined 3.92 inches of rain on January 8 and 9. With all this water pouring into Mono Lake, I set out with my coworker Andrew to measure the lake level on cross country skis.
