CLEAN Nutrient Dashboard


The CLEAN Nutrient Dashboard evaluates management options for wastewater, stormwater and agricultural operations in Colorado. The dashboard was developed in partnership with the U.S. EPA and Colorado Department of Public Health and Environment (CDPHE) to help watershed managers analyze scenarios to implement nutrient abatement requirements from Colorado Regulation 85 – Nutrients Management Control Regulation.

A user can apply a portion or all available information sources to analyze nutrient management scenarios in a specified area ranging in size from a HUC-12 watershed up to a regional-scale analysis. The Dashboard will also allow users to input their own data and upload various land use configurations to analyze future growth scenarios.


Tool Outputs

This tool estimates nutrient load (total nitrogen and phosphorus) per source category (urban stormwater, wastewater treatment facilities, agriculture, and background) on an average annual basis. Graphical plots include scenario comparison of loads based on different managements, category comparison of total watershed nutrient load sources, and observed ambient water quality load estimates.
