CARSON CITY, Nev. The U.S. Geological Survey, in collaboration with the Desert Research Institute and the Walker Basin Conservancy have produced estimates for potential river flows and changes to Walker Lake from the 2017 snowpack melt. The USGS model simulations indicate that high flows will be present for the Schurz Community and may persist through mid-July before starting to abate. Although this reach of the river is dry during most summers, it appears that flows could last into October this year.
