The Colorado Water Quality Control Division (WQCD) is developing new watershed and Bear Creek Reservoir models for the development of a new Total Maximum Daily Load (TMDL) for Bear Creek Reservoir and watershed.  The WQCD is using independent consultants that are relying on water quality data generated by the Association. The watershed and reservoir models are scheduled for completion by January 2021 with a subsequent TMDL completed by the fall of 2021. A Rulemaking Hearing will be scheduled before the Water Quality Control Commission by 2022 to update the Bear Creek Control Regulation # 74.

 

The modeling efforts will develop predictive models of Bear Creek watershed and reservoir with a focus on nutrients and nutrient management.
•Total phosphorous and total nitrogen
•Use models to identify sources, inputs to the reservoir and reservoir dynamics
•Define potential management scenarios to control nutrient inputs
•Incorporate management scenarios into models
•Technology transfer
