Table 1. Explanation
1. Reservoir Surface Elevation - Surface elevation, used to
determine head for power plants.
2. Reservoir Contents - Reservoir contents as a function of
elevation.
3. Reservoir Surface Area - Surface area, used to determine
evaporation losses.
4. Outlet Works Capacity - Maximum discharge, used to model
spills. HYDROSS tries to route all releases through the
outlet works; releases which won't fit through the
outlet works are spills. HYDROSS uses the mean
reservoir content (average of beginning-of-month and
end-of-month contents), and performs linear
interpolation on the tables to determine the elevation,
area, and maximum discharge for the month.
