CDPHE Tools: Low Flow Analysis
The Colorado Department of Public Health and Environment’s (CDPHE) Low Flow Analysis tool queries, analyzes, and organizes stream flow data with various options for low flow design flows (e.g., extreme-value, biologically based, human-health or Regulation 31).
The Low Flow Analysis tool was developed in conjunction with Colorado State University’s One Water Solutions Institute and the Colorado Department of Public Health and Environment’s Water Quality Control Division.
The tool uses publicly available and/or user supplied data to analyze various aspects of streamflow data including multiple assessment methodologies for low flow conditions. The low flow analyses are based on DFLOW developed by the U.S. Environmental Protection Agency and aid in designing state discharge permits.
