  • Dogs must be on a leash April 1 through July 31
  • Seasonal restrictions to human entry from February one to March 15 (see restricted area map)
  • Camping and camp fires are prohibited at Deer Park WMU

The Deer Parks Wildlife Mitigation Units are three separate parcels of land located along and near the South Fork, Henrys Fork and mainstem Snake rivers – Menan, Beaver Dick and Deer Parks. The name ‘deer parks’ comes from early settlers descriptions of the thick willows and cottonwoods that supported large numbers of deer.  

County roads provide access to the mitigation units and parking lots are provided on all of the Deer Parks unit. Public use of Deer Parks WMU is limited to non-motorized travel on uplands and interior water bodies.

Overview

The Deer Parks Wildlife Mitigation Units were acquired as partial mitigation for wildlife habitat lost by the construction of the Palisades dam and reservoir, especially mule deer habitat.  The name ‘deer parks’ comes from early settlers descriptions of the thick willows and cottonwoods that supported large numbers of deer.  The mitigation units are also important stop-over and open-water winter habitat for migrating waterfowl, waterbirds and shorebirds.

Deer Parks has documented more than 3,000 trumpeter swans wintering on the property. This is up to ten percent of the entire Rocky Mountain population.

Some mule deer use the wildlife mitigation units for spring fawning and rearing.  Most mule deer in the area move to one of the two nearby Menan Buttes for the winter and use the units for forage. White-tailed deer occupy all segments of the WMA year-round.

The Deer Parks Complex includes three separate properties – Menan, Beaver Dick and Deer Parks - that run along and near the South Fork, Henrys Fork and mainstem Snake rivers

  • The Deer Parks Unit, also known as the Menan and Boyle segment, is located on the mainstem Snake River in Jefferson County. The property includes two miles of riverfront, wetlands, uplands, pasture and cropland.  A paved county road is adjacent to the property.  The North Menan Butte is partially within the Deer Parks unit and rises 800 feet above the surrounding landscape.
  • The Twin Bridges Unit is located along the  South Fork Snake River in Madison County near Ririe, Idaho.  This property includes riverfront, wetlands, former pasture and cropland. A paved county road is adjacent to the property.
  • The Beaver Dick Unit is located along the Henrys Fork Snake River in Madison County.  The property includes one mile of riverfront, wetland and former pasture. State Highway 33 is adjacent to the property.

The properties are owned by the Bureau of Land Management (BLM) and managed cooperatively with Idaho Fish and Game, the BLM and Shoshone-Bannock Tribes. 

Tribal treaty rights are maintained and cultural resources are protected through the NEPA process on all segments of the Deer Creek Wildlife Mitigation Units.

Hunting

Most of the Deer Park WMUs fall within Game Management Unit (GMU) 63A. A small portion is north of Highway 33 and is in GMU 60A. Hunters often hunt for mule deer, white-tailed deer, pheasant, moose and waterfowl.

Mule deer hunting season is controlled hunt permit only. White-tailed deer permits are general season opportunity.

Moose hunting is a controlled hunt permit only and can be found on all Deer Park parcels.

Elk have used the WMUs in the past but have rarely been seen in recent years.

Turkeys can be found along the Snake River corridor and on all Deer Parks Units.

In the fall, secret coves and backwaters of the Snake River provide nice places for waterfowl hunting.

Note on Blinds: Anyone can construct or erect a blind on the WMU. Blinds must be constructed of natural materials. No artificial fasteners such as nails, wires or ropes are allowed. Soils cannot be disturbed and trees cannot be cut or altered. These blinds shall be available to the public on a "first come, first served" basis. Portable blinds are welcome, but must be removed each day.

Tree stands must be removed after hunting season.

Trapping

Furbearer trapping is allowed on the WMUs. Trappers must register with the Upper Snake Regional Office or WMA staff. 

Wildlife Watching

Almost any species of waterfowl found in southern and eastern Idaho can be found here, including red-breasted mergansers and trumpeter swans. Deer Parks has documented more than 3,000 trumpeter swans wintering on the property. This is up to ten percent of the entire Rocky Mountain population.

In the spring, migrating songbirds and raptors fill the cottonwood forests, making Deer Parks WMUs hot spots for birding.
