PARK UPDATE:

September 10, 2021:

Attention Visitors: Eastern Idaho Public Health and the Department of Environmental Quality (DEQ) have issued a health advisory for Henrys Lake and upper portions of Island Park due to the presence of
Harmful algal blooms (HAB) in the water. The blooms can be extremely toxic to humans and animals and we ask that all visitors adhere to the following recommendations:
– Do not ingest the water
– Do not allow children or pets to swim in the water
– Fishing is okay, but DEQ recommends removing the fat, skin, and organs before cooking. Wash hands often and cook only the filet portions of the fish prior to consumption.
Thank you for your understanding!

March 2021:

Due to problems with the drain field, the Dump Station at Henrys Lake State Park will be closed for, at least, the 2021 season.   A study will be completed in 2021 to see if the station will be replaced or it is not feasible with today’s protocols.

Alternate Dump Stations are:

  • Bing Lemke Forest Service Dump Station, Last Chance, 20 miles south of the Henrys
  • Ashton Visitor Center, 43 miles south
  • Grizzly RV is available in West Yellowstone, 15 miles east.

The only sewage dump at the park will be the FULL hook-up sites.

We are sorry for the inconvenience.
