The application of aerial and satellite snow-mapping techniques for multi-purpose reservoir system operations in Arizona

Multipurpose reseroir system operations in central Arizona requires timely and dependable snowmelt information. This requirement led to aerial snow-mapping on the Salt and Verde watersheds in late 1965. Snow maps have proven to be a valuable decision-making tool for system operations. The maps have also been used in verification and improvement of satellite snow-mapping technique which was successfully applied by the Salt River Project during the 1975-76 runoff season under the NASA-ASVT program. Preliminary hydrologic analysis of snowmelt runoff is being made. Timely satellite snowpack information is being integrated into the decision-makeing process for multi-purpose reservoir system operations in Arizona.
