Reservoir ‘Teacup’ Diagrams for Upper Colorado Basin and the Wasatch Front
These diagrams are generated daily by Reclamation based on their latest operational data. The fraction that each tea-cup symbol is filled indicates the current reservoir contents as a fraction of the capacity (i.e., % Full). The size of the teacup is not proportional to the capacity of the reservoir. The first two values provided next to each teacup (e.g., 208746/344800) are the reservoir contents in acre-feet and the capacity in acre-feet, respectively.
Additional reservoir teacup diagrams or operational data for Colorado, Utah, and Wyoming can be accessed as follows:
Great Plains region of Reclamation (includes Bighorn Basin, Boysen, Buffalo Bill, Colorado-Big Thompson, Fry-Ark, North Platte, Wind River)
Upper Colorado Region of Reclamation (includes Upper Colorado River Basin, Upper Rio Grande Basin, and nearly all of Utah).
For reservoirs that are not operated by Reclamation (including Bear Lake, Dillon Reservoir, Strawberry Reservoir, and many others), see the NRCS State Basinwide Reservoir Summaries (updated monthly).
