Development and Interpretation of Daily Seasonal Water Supply Forecasts

This Technical Note documents the process used to develop the Daily Water Supply Forecast procedures and serves as a guide for helping users interpret the results.

This product was developed to supplement official water supply forecasts generated at the beginning of each month during the water supply season. The water resource community requested daily calibrated water supply forecasts to aid in the assessment of increased climate variability. The Natural Resources Conservation Service (NRCS) National Water and Climate Center (NWCC) developed these procedures that use hydroclimatic data collected by the SNOTEL and USGS data networks.
