Water outlook & drought

 Water outlook & drought

As your local water provider, we have a responsibility to protect your water supply and help ensure the health, safety and economic vitality of our community. We carefully monitor several factors, including levels of our reservoirs, snowpack and forecasted stream flow.

As of July 1, 2015

Current reservoir levels
System wide, total water storage is at 93 percent of capacity, which is 10 percent above average (1981 through 2010).

Current situation
In June, the average temperature was above average and total precipitation was over twice the average, as measured at the airport. The U.S. Drought Monitor shows abnormally dry conditions across western Colorado. Drought has ended across the rest of the state.

We have three years of demand in storage.

Lower demands and above average precipitation have kept storage levels higher than normal. Local storage levels continue to increase due to local rain and runoff.

Currently, the Water Shortage Ordinance is set at Stage 1 Voluntary Restrictions, which means customers are asked to continue to use water wisely.

How does Colorado Springs Utilities determine that we are in are in a drought?
There are a variety of factors used to determine when we are in a drought including: long range forecasts, storage levels, snowpack, operational constraints, soil moisture and others. If total system storage is projected to be below 1.5 years of demand in storage on April 1 then the results are reported to the City Council with a recommendation for implementation of water shortage response measures.

How do we determine what Water Shortage Ordinance stage we are in?
Our water supply staff create a forecast of water storage levels.  If the forecast shows that storage will get below our risk tolerance threshold of one year of demand in storage, experts estimate how much water savings will be needed to keep us at or near that threshold. Each stage of drought response has a corresponding estimate of expected water savings associated with it. We set the Water Shortage Ordinance stage by matching the amount of savings needed with the amount of savings expected from the various stages.
