This report contains streamflow and ground-water-level data collected from Statewide networks as part of cooperative programs between the U.S. Geological Survey and the Georgia Department of Natural Resources, Environmental Protection Division, Georgia Geologic Survey and other State and local agencies. Reservoir elevation (used to calculate reservoir storage) and precipitation data were provided by the National Weather Service.
Table 1. --Hydrologic data for selected precipitation-monitoring stations [Value and averages are precipitation, in inches. Long-term average based on 30-year reference period, 1961-90. Annual departure is cumulative departure of annual precipitation from long-term average. Data from National Weather Service.
