Waterflow Reports

River Flows  

Streamflow data provided by the U.S. Geological Survey for:

  • Box Canyon
  • Ora
  • St Anthony
  • Reservoir Levels

One improvement to protect population-level benefits to the wild trout population is providing adequate water to juvenile trout at critical times. HFF actively works with Trout Unlimited and local government agencies to ensure “fish-friendly” flows. Learn More.
