Denver Water diligently collects and analyzes data from throughout our system to help us better understand where our water supply and demand stand.
Daily raw water updates
Denver Water collects readings at diversions and reservoirs throughout the system and provides daily updates year-round. The data reflect average conditions over the course of 24 hours at reporting locations. All data are preliminary and subject to change. For additional data needs, contact Raw Water Supply.
- Reservoir Operations: Readings taken at stream gages and reservoirs in Denver Water's collection system.
- Diversions: Water diversions at different tunnels, canals and ditches in Denver Water's South Platte and Moffat collection systems. The amount of water Denver Water diverts affects streamflow rates throughout the watershed.
Streamflow is how much water, in cubic feet per second, is flowing at different locations along the South Platte and Colorado rivers. Streamflow rates depend on natural flow levels, Denver Water’s diversions and others’ diversions into reservoirs, tunnels, canals and ditches.
The Colorado Division of Water Resources and the U.S. Geological Survey provide current information from these stream gages.

Water Watch Report
The Water Watch Report is a summary of water supply and demand conditions (e.g., reservoir supply, snowpack and precipitation) prepared for Denver’s Board of Water Commissioners. During the winter, the report is updated the Monday before Board meetings, which are normally the second and fourth Wednesdays of the month. During the watering/irrigation season, it is updated weekly.
On a daily basis, Denver Water provides weather reporting and data with information on conditions such as temperature, rainfall and evapotranspiration.
