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.

This morning Mono Lake Committee staff met with Los Angeles Department of Water & Power (DWP) personnel to conduct the official annual April 1 reading of the lake level together. The consensus: Mono Lake stands at 6378.11 feet above sea level.
Mono Lake is now just 13 inches above the ecologically precipitous 6377-foot elevation at which the nesting islands become landbridged, lake salinity hits new highs, air quality problems worsen, and stream delta habitat conditions degrade.
With those concerns in mind, the State Water Board rules are more nuanced this year for determining whether or not DWP can export water to Los Angeles. Not only does the lake have to be above 6377 feet for today’s measurement, it also has to be forecast to stay above 6377 every day of the coming year. (more…)
This morning Mono Lake Committee staff met with Los Angeles Department of Water & Power (DWP) personnel to conduct the official annual April 1 reading of the lake level together. The consensus: Mono Lake stands at 6379.01 feet above sea level.
The lake has declined to a level at which water exports to Los Angeles are, by the terms of the State Water Board’s rules, automatically reduced by 70%. DWP will be limited to 4,500 acre-feet of water export, a lake-protecting restriction that no one, until recently, thought would ever be activated again. It was a solemn, though not unexpected outcome, given that California’s drought is entering its fourth year and the Mono Lake watershed is officially classified as being under “exceptional” drought.
