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.
