East Canyon Reservoir Algal Bloom Monitoring 2020

Warning Advisory

  • Do not swim or water ski in this area.
  • Avoid areas of algae scum when boating.
  • Keep animals away.
  • Do not ingest the water.
  • Clean fish well and discard guts.

Due to state budget cuts, the harmful algal bloom program is being funded by EPA through a one-time grant. This limits DWQ’s monitoring to 18 priority waterbodies in Utah.
