Why?
-
Flat Creek is an important Yellowstone Cutthroat Trout spawning tributary that has been adversely affected by urbanization, rural land development, and water management.
-
The section of Flat Creek south of the town of Jackson is poor Yellowstone Cutthroat Trout habitat: it is overly straight, wide, and open, and contains movement barriers that limit access to good spawning habitat.
-
There is ample hydrology and watershed function from upstream sources to improve instream habitat and water quality throughout a degraded, channelized section of creek.
-
Improved stream function will reduce stream bank erosion, restore reference channel dimension and riparian vegetation, reduce localized winter icing problems, diversify instream habitat, and address stream warming.
- These changes will result in improvements to Yellowstone cutthroat Trout habitat.

How?
-
A total of 1.2 miles of Flat Creek will be restored to reference conditions, with Phase II (current phase) focusing on 0.6 miles of the waterway.
-
The riparian area will be restored using a combination of grazing exclosure fencing and extensive planting of willow and cottonwoods.
-
The new channel will be narrower and deeper, and have connection to its floodplain through the installation of meander bends, toewood, and vegetated soil lifts.
-
Seasonal barriers to upstream fish movement will be retrofitted to allow for year-round passage.
