Abstract: The Walker Basin Restoration Program was established by Congress as part of Public Law 111-85 in October 2009. The Program’s core purpose is to restore and maintain Walker Lake, a natural desert lake in Nevada at the terminus of the Walker River stream system of Nevada-California. Walker Lake is critical to recovery of the threatened Lahontan cutthroat trout (LCT) and is an important stopover for common loons and other migratory birds. However, many decades of depleted freshwater inflows have resulted in declines of lake elevation and increases in lake salinity, which today threaten its complete ecological collapse. In order to reverse Walker Lake’s decline, the National Fish and Wildlife Foundation (NFWF) seeks to increase instream flows to Walker Lake through a comprehensive basin-wide strategy that includes voluntary water transactions and water management initiatives. A key element to the restoration program is the development of numerical tools that can simulate the hydrologic system within the basin. A variety of hydrologic models have been created to simulate the important relationships among climate, crop demand, river flows, groundwater-surface water exchange along the river and delivery ditches, irrigation practices, groundwater pumping, and all known existing water rights in both Mason and Smith Valleys. This presentation highlights the numerical tools including results showing the impacts of hypothetical water transfers on the river and groundwater systems.
