Grand Teton National Park
Two Oceans Lake Culvert Removal
PROJECT NUMBER 2002-0311-010.5
NFWF & JHOF Partnership: $5,000
Local Match: $7,000
Grand Teton National Park was established to protect the area’s native
plant and animal life and its spectacular scenic values, as
characterized by the geologic features of the Teton Range and Jackson
Hole. The parks Strategic Plan highlights the significance of the Snake
River as habitat for cutthroat trout and as a recreational resource,
along with the abundant mammal, plant and bird species that reside in
the park. The parks 1997 Snake River Management Plan emphasizes the
desire to maintain the river’s natural character in order to protect
wildlife and scenic values.
The Jackson Hole One Fly Foundation - National Fish and Wildlife
Foundation Conservation Partnership Program is providing funding for
this program to help ensure the survival of cutthroat trout in Two
Oceans Lake.
 Annually,
since 1965, the Wyoming Game and Fish Department (WYG&F) stock the lake
with 30,000 cutthroat trout. Fisheries biologists have identified a
culvert that is a barrier to native fish migration. If this culvert were
replaced or modified to allow upstream migration of fish, the need for
stocking of Two Ocean Lake would be eliminated, and natural processes
could be restored. This project proposes to replace the existing
culvert. Once this is complete the WYG&F will discontinue stocking of
Two Ocean Lake, allowing natural migration to maintain cutthroat trout
populations.
Project Status:
Work was completed on the Two Ocean Lake culvert replacement on April
22, 2004. Two rock weirs were installed below the existing culvert to
improve fish passage. Also streambanks were revegetated with native
willows.
