Sign up for Construction Updates here!

Construction Update April 12, 2024:

  • Due to short-term construction needs, some heavy equipment will use Hatchery Road on Monday and Tuesday, April 15th and 16th. The contractor has been directed to operate no earlier than 7 a.m. on those days.
  • Highway 44/State Street entrance will remain closed through June 2024. Please continue to use Hatchery/Linder Road until directed otherwise. Please stay out of the fields and be respectful of construction areas and workers.
    • The extended closure is a change from the original plan and is intended to make up for construction delays and to avoid a second planned closure in the fall.
Attention Park Visitors: Please adhere to trail closure signs during the construction process. The shop road/horse trailer access road is currently closed but will reopen when it is safe to do so. We ask that horse trailers please use our overflow gravel parking lot for the time being!
Note: The completed campground will not impact trail areas, this is only temporary while work is being done. Thank you!

Historic Building Renovations:

The park will also be working on historic building renovations. Please be mindful of workers in the area.

Eagle Island State Park in mid-2022 enacted a new policy regarding dogs off-leash and has designated an area and trails that are open to off-leash dogs that are under the demonstrated control of their owners. Click here for details.

Pet restrictions are now in place at Eagle Island State Park. But there are still places to take your dog.

For Your Health

For your health, and to keep this popular recreation area open and accessible for your enjoyment, the Idaho Department of Parks and Recreation (IDPR) has adopted a “no pets in the lake” policy at Eagle Island State Park.

Pet feces (direct, on fur, and paws) is a major cause of harmful bacteria in recreational waterways.

  • Keep pets on a leash when in the park
  • Always pick up pet waste
  • No pets allowed on beach or in lake

Off-Leash Areas: A Pilot Program

The Department has implemented a pilot program to create off-leash areas within the park. Per state law (IDAPA 26.01.20.175.09), dogs must be on a leash at State Parks, but the department has the ability to designate off-leash areas.

Dogs are now allowed to be off-leash on designated, off-leash trails and in the newly designated Dogs Off-Leash Area (please see map) – but only if the owner demonstrates control over their animal(s). Having control of an off-leash dog means the owner prevents the pet from disturbing other park visitors and wildlife, and the owner has the ability to recall the animal at any time.

The 212-acre, Dogs Off-Leash Area is south of the main access road, and south of the old Slaughterhouse and Warden’s House (dark green shaded area on map). Please note that the area remains a working farm, so dog owners can expect flood irrigation. Two areas where dogs have formerly been allowed off-leash, north and south of the Prison Dormitory Road, will no longer be available because of the new campground and associated pond, which will break ground in the spring of 2023.

  • Off-Leash Area Requirements: Dogs cannot harass people, wildlife or other pets. Owners must carry a leash, waste bag, and clean up after their animal(s).
  • Off-Leash Trail Requirements: An unleashed dog must be within 30 feet of its owner and under voice control. Dogs cannot harass people, wildlife or other pets. Owners must carry a leash, waste bag, and clean up after their animal(s).
