The University of Colorado Denver | CU Anschutz Medical Campus Municipal Separate Storm Sewer System (MS4) connects to the City of Aurora MS4 which discharges to Toll Gate Creek where it ultimately leads to the South Platte River and Barr Lake/Milton Reservoir. The Barr-Milton Watershed includes Denver, Englewood, Littleton, Aurora, Thornton, Lochbuie, Brighton and many other municipalities. See the Milton-Barr Watershed Map below to see what this watershed encompasses.
Owned by the Farmer’s Reservoir and Irrigation Company (FRICO), Barr Lake and Milton Reservoir were constructed around 1909. Until 2002, the reservoirs’ main purpose was to supply water for irrigating agricultural crops. In 2002, both reservoirs began to be used to supply drinking water. Historically, both Barr Lake and Milton Reservoir have been some of Colorado’s most nutrient-rich reservoirs and have been hyper-eutrophic due to hi nutrient and organic loads from the South Platte River. Because of this, Barr Lake and Milton Reservoir have a pH and dissolved oxygen total maximum daily load (TMDL) which is controlled by targeting phosphorus. The TMDL seeks a 20% reduction in phosphorus loads on these waters. For more information about the Barr Milton Watershed, see the Barr Milton Watershed Association at: https://barr-milton.org/
By practicing healthy pollution prevention habits, our community can keep pollutants like dirt and common garbage that collect on paved areas from being washed into storm drains. You can help to prevent stormwater pollution by:
To minimize pollutants transported by stormwater runoff, the
University of Colorado
Denver | CU Anschutz Medical Campus implements programs in accordance
with the Non-Standard Colorado Municipal Separate Storm Sewer System
(MS4) Permit. The university is required to administer a Non-Standard
Municipal Separate Storm Sewer System (MS4) permit, Colorado Department of Public Health and Environment (CDPHE) Permit
#COR-070075. The University of Colorado
Denver | CU Anschutz Medical Campus
has a stormwater program which includes routine inspections on water
quality facilities, targeting of excess nutrients, and education and
outreach components. For more information on Colorado MS4 permits, see the MS4 General Permits section of the CDPHE website.
Public involvement is a critical part of the success of our stormwater program. University of Colorado Denver | CU Anschutz Medical Campus seeks public involvement in the following ways:
To request a copy of our Program Description Document (PDD), which outlines the university's Stormwater Pollution Prevention Program, please contact the Regulatory Compliance Manager. If you have any questions, concerns or ideas about our stormwater pollution prevention program, please also feel free to contact the Regulatory Compliance Manager.
In accordance with state regulations, the University of Colorado Denver | CU Anschutz Medical Campus runs an Illicit Discharge Detection and Elimination program which seeks to identity and eliminate any potential illicit discharges throughout the campus. For more information on illicit discharges or to report an illicit discharge, please see the Discharge Detection page.
The University of Colorado Denver | CU Anschutz Medical Campus discharges to Barr Lake and Milton Reservoir which have a pH and dissolved oxygen total maximum daily load (TMDL). This nutrient loading is controlled by targeting phosphorus with the TMDL seeking a 20% reduction in phosphorus loads on these waters. For more information on TMDLs and what we do to reduce phosphorous loading on campus, see Pollution Prevention.
