Drought

Colorado has experienced lower-than-normal precipitation since 2020. Aurora Water is carefully monitoring both our water mountain water supply and our in-town demands. This page will be updated regularly to help keep our customers informed.


Aurora's water availability status is NORMAL.

Under Normal status, watering is permitted no more than three days per week. From May 1 to September 30, watering is not permitting between 10:00 a.m. and 6:00 p.m.


To preserve Aurora's water to meet life, safety and health needs, Aurora Water created a Water Management Plan. The Water Management Plan provides a series of responses to reduced water supply conditions to achieve progressively higher levels of water savings, or “stages” that result in reduced demand by restricting the use of water for landscape irrigation and other outdoor water uses. A stage declaration is based on the status of the water system and appropriate responsive action.

Aurora stores water in 12 reservoirs across three river basins. Our goal is to maintain over 30 months of water demands in storage to help buffer us from Colorado's drought cycles.

 * Aurora is in many reservoirs across Colorado. Since we move our water to meet many needs, this number represents Aurora’s water in these other reservoirs at this time. All numbers in this report should be considered to be an estimate or projection. Included in shared storage is Aurora's share in Homestake Reservoir, Turquoise Lake, Twin Lakes Reservoir, Pueblo Reservoir, Strontia Springs Reservoir and Lakes Meredith and Henry

Snow Report - Mar. 1, 2021 - 92% of average
This weekly report reflects the depth and moisture content of snow in the three basins that Aurora diverts its water from.

There are two measurements included in the report. We pay close attention to the “Snow Water Equivalent” or SWE. This measurement takes into account the snow’s moisture levels, which helps determine how much runoff we may see in our diversion systems. This number is not perfect and cannot be used to predict reservoir levels. Many factors come into play with snow runoff, including the speed of the runoff due to temperature (too fast and we can’t collect all of it), humidity levels (dry air can result in direct evaporation or sublimation) and soil moisture (dry soils siphon moisture off before it can reach our diversions).

50% of Aurora's water comes from the Upper Souths Platte Basin
25% of Aurora's water comes from the Colorado River basin, mostly from the Homestake Valley in the Eagle River sub-basin
25% of Aurora's water comes from the Arkansas River Basin
