Watershed Projects Preserve Water Quality

There are numerous factors that affect water quality in the Chatfield Reservoir, with some having a larger impact. As the uses of the reservoir change, and the growth of the urban areas continue, so does the impact of pollution. Projects implemented by the Authority work to preserve water quality in the Chatfield basin, watershed and reservoir.

The projects address:

  • Agricultural Activities
  • Septic Systems
  • Streambank Stabilization
  • Wildfire Management
  • Water Quality and Habitat Improvements
  • Plum Creek Water Monitoring

 

Current Projects

The Pine Canyon Water & Sanitation District
The Pine Canyon Water & Sanitation District has submitted to the Chatfield Watershed Authority a Trade Application Engineering Report. The trade proposes to reduce phosphorus loading to the watershed as a non-point to point source phosphorus trade through development of the Pine Canyon Water Reclamation Facility. The Trade Application can be accessed using the following link, Pine Canyon Water Reclamation Facility Trade Application Engineering Report.

 

Chatfield Storage Reallocation Project
In addition to flood control, Chatfield Reservoir recently added drinking water storage to its purpose. With the growing demand for water in Colorado’s Front Range and northeast Colorado farms, the U.S. Army Corps of Engineers (Corps) approved expanding the reservoir by 20,600 acre-feet for drinking water. The Chatfield Storage Reallocation Project, completed in 2019, required modifications for the recreational components of the park and environmental mitigation to restore and enhance the wildlife habitat.

The Authority is currently monitoring water quality data and analyzing the changes occurring from additional water flow through the watershed and into the reservoir.

 

Plum Creek Streambank Stabilization
In collaboration with the Authority, Castle Rock Water is managing several current and proposed drainageway improvements along East and West Plum Creek. These projects enhance and, in some cases, reconstruct the natural floodplains in the Town of Castle Rock. This infrastructure serves to reduce public risk from stream channel erosion and flooding. These projects also have a water quality component that ensures our renewable drinking water supplies are preserved and protected.
