JUST A REMINDER
Please remember to close the gate(s) we go through as
we pass through the new fence.
This project is a safety enhancement wildlife fence project that is funded by several interested agencies both public and private. This project includes work adjacent to 8.95 miles of US 97A from Rocky Reach Dam to Spencer Canyon. By installing the fence along this high deer kill section below the Swakane Wildlife Area, it is anticipated that a 50% reduction in total vehicle-wildlife collisions for the entire 40-mile corridor can be achieved.
This corridor has one of the highest mule deer and big horn sheep mortality rates in Washington. As many as 160 deer are reported killed along the highway during a severe winter between Wenatchee and Chelan.
The fence was built with funding from the Washington State Department of Transportation, the Washington Department of Fish and Wildlife, as well as private donors.

FAQ's about Wildlife Response to the Fence
For more information on the 97A Wildlife Fence, please call WDFW at (509) 662-0452
1 ) Will the fence disrupt Mule deer migration patterns ?
§ No: Deer migrate down in elevation in response to snow depth to find forage and browse, and the fence will not impact this as there is very little habitat being blocked off by the fence
§ The Columbia River has always been a barrier to deer migration.
2 ) Will the fence block Mule deer and Bighorn sheep from food ?
§ No: Development has already eliminated most foraging in the foothills above the highway.
§ Mule deer and bighorn sheep are adapted to nutritional stress in the winter and are able to survive on existing habitat.
§ Some mule deer and bighorn sheep feed on ornamental landscaping in the highway corridor, but this is not a critical food source.
3 ) Are the Mule deer and Bighorn sheep crossing the road to access the river and will the fence block them from water ?
§ No: Mule deer and bighorn sheep are not using the Columbia River for their sole source of water. If they were water stressed, we would see collisions during the summer, not during the winter.
§ Most collisions occur during winter and early spring, when there is plenty of water available from the rain and snow.
§ These animals are adapted to arid climates and survive in areas with little water.
§ They get much of their water from vegetation (water within the plant) and dew (during morning forage).
§ Both these animals will eat snow for moisture.
§ There are numerous guzzlers (man made water collection devices), in the foothills above where the fence will be placed that provide a source of drinking water.
§ Mule deer can live up to 2 miles from permanent water sources.
§ Surveys show thousands of deer in the foothills above the fence, and we do not see thousands of deer crossing the highway to drink.
4 ) Are the Mule deer and Bighorn sheep coming to the road to lick salt/minerals ?
§ Unknown: Both species have been observed licking roadways and eating dirt near the highway.
§ Salt or minerals near the highway may be present naturally or from road maintenance activities, but it is doubtful they need these to survive.
§ There are natural salt and mineral deposits that exist in the foothills above the fence for them to use, additionally, WDFW can place salt/mineral licks if necessary.
5 ) Will wildlife get trapped on the other side of the fence ?
§ No: If an animal finds itself on the highway, there will be many escape doors within the fence that allow passage formt he highway, but not to it. Wildlife are very good at finding “weak” points in a fence.
§ In the event that a large herd of mule deer or bighorn sheep find themselves on the highway side of the fence, WDFW will coordinate with State Patrol to safely herd the critters back to the other side of the fence.
6 ) Will Mule deer and Bighorn sheep just go around the ends of the fence to get to the road ?
§ Doubtful: The fence will be engineered into cliffs that already prevent wildlife movement.
§ Mule deer and bighorn sheep are habitual animals that rarely leave their home ranges, and would not likely travel miles to get around a fence.
