Hydrography
The surface area, surface elevation, and water volume of the reservoir fluctuate based on inflow and local climatic conditions. In terms of capacity, the Corps of Engineers vertically divides the reservoir into a set of pools based on volume and water level, and the reservoir is considered full when filled to the capacity of its conservation pool. When full, El Dorado Lake has a surface area of , a surface elevation of , and a volume of . When filled to maximum capacity, it has a surface area of , a surface elevation of , and a volume of .
The streambed underlying the reservoir has an elevation of .
