River Basin Tea-Cup Diagrams

By selecting one of the river basin links below, you will be taken to a map of that basin.  Each of the major Reclamation Reservoirs in the basin will be represented by a Tea-Cup Diagram such as the example seen below.  The level of blue fill in the Tea-Cup represents the level of fill in the reservoir.  Below the Tea-Cup you will find the name of the reservoir, a ratio of the volume of water currently in the reservoir to the volume of water in the reservoir when it is full, and the percent full.  In the example Tea-Cup Diagram below the reservoir currently has a volume of water equal to 16,007,788 acre-feet, when the reservoir is full the volume of water is 24,322,000 acre-feet, resulting in the reservoir being 66% full.  The data represented is checked for accuracy, however all data is subject to revision.
