Colorado Cutthroat Trout Habitat Enhancement
WYGFD 4-WS-94-326 $11,300
Currant Creek, a tributary to Flaming Gorge Reservoir, is a high priority for trout
habitat enhancement work in the upper Colorado River drainage. Wyoming
Game and Fish Department installed instream fish habitat structures to improve
trout habitat conditions, provide channel stability, reduce erosion, trap sediment
and widen the functional riparian zone.
Freshly cut trees were fixed in the stream and banks in an "X" configuration at 40
separate locations along Currant Creek. Such structures introduce woody debris
to the stream, provide low velocity shelter, and trap sediment to build riparian
vegetation and improve bank stability. In addition, revetments were constructed
at three locations to retard actively eroding banks. About 555 aspen saplings (3-
6 feet tall) were planted along the stream banks adjacent to and downstream of
the instream structures to reestablish aspen in the riparian zones.
Colorado Cutthroat Trout Habitat Enhancement
CDOW 4-WS-94-328 $7400
The Colorado Division of Wildlife initiated and maintains ongoing efforts to
sustain existing pure strain Colorado River cutthroat trout (CRCT) populations
and improve habitat conditions for this native trout species. Under this project,
the DOW reinstalled a fish barrier in Roan Creek that had previously been
dislodged by high flows. An effective barrier prevents non-native trout from
moving upstream into the upper elevations of streams still inhabited by CRCT
where they can introgress (interbreed) and destroy the pure strains of genetic
stock. DOW personnel then intensively electrofished the upstream reaches of
the creek, finding only two non-CRCT trout, which were relocate below the
barrier. Remaining fish were considered CRCT, following genetic analysis of
sample fish removed from the stream. DOW will monitor Roan Creek, by means
of additional genetic analysis of fish, for several years to determine if
introgression is occurring.
Fontenelle Wetlands
WGFD/BOR 4-FC-CU-WG010 $18,150
Wyoming Game and Fish Department and the Bureau of Reclamation worked
together to plan a wetland consisting of four large ponds equipped with water
