RIPARIAN RECOVERY
Lake Creek, Central Idaho 1993 - 2009
~ Jon Marvel
Friends,
In early September 1993 three friends visited Lake Creek in the watershed of the East Fork of the Salmon River in central Idaho.
We observed severely damaged riparian conditions caused by cattle permitted to graze by the Challis National Forest and the Challis Field Office of the BLM. Looking at the map we noticed that one-mile of this damaged area on Lake Creek was located on a 640-acre section of Idaho State school endowment land.
Idaho Watersheds Project was created shortly after that experience to apply for and competitively bid for that very same grazing lease. After six years of legal fights and a number of court decisions, all won by IWP, the grazing lease was awarded to IWP in 1999. Thanks to long-time WWP members Bob and Barbara Dargatz, WWP has held the lease ever since.
These photographs taken in 1993 and 2007 show the dramatic and remarkable improvements since 1993 to the damaged riparian area on Lake Creek that resulted simply by removing livestock.
This passive restoration of Lake Creek has recovered stream health, water quality and wildlife and fisheries habitat at little cost.

dries more quickly, erodes more easily, weeds replace beneficial
vegetation, and the water level lowers, dropping below the roots of
willows and other riparian vegetation.

filter sediment for fish, store water recharging the aquifer, and
promote general stream-bank (riparian) health

bank. The sediment settles in between gravels depriving salmon fish
eggs of the oxygen they need to thrive.

replaced by weeds, the whole area loses moisture.

shrews, bugs and insects that nourish fish, birds, and other wildlife -
forming the basis for the entire food-chain
photo: Idaho Department of Lands - July 18, 2007 - Lush grasses feed riparian soils too - the rich organic matter
resulting from dead and decaying plant-life become a part of the soil
acting like a sponge, filtering and holding more water longer,
promoting even more plant-life

These photographs illustrate Western Watersheds Project's vision for riparian areas across the West.
