Project Description

In 2013, CalTrout helped negotiate the Mono Basin Settlement, ending decades of lawsuits and strife over how much water could be diverted from four key Mono Lake tributaries to serve Los Angeles water users. Today, we are continuing to ensure full implementation of the settlement to protect the Upper Owens River headwaters and Mono Basin fisheries; actions include upgrading Grant Dam and the subsequent delivery of long-term flows, as well as an extensive monitoring program.
