Abstract:
Bathymetry for Lake Berryessa

Purpose:
To provide approximate lake depths. This is an ESRI ASCII grid of the Lake Berryessa bathymetry, The grid was generated by the Solano County Water Agency (SCWA), from a DTM of the Berryessa lake basin. The resolution of this grid is 10-ft. The glory hole adjacent to the Monticello Dam was used as the vertical datum for the original DTM. Therefore, a "0" water depth is at the glory hole elevation.
