Grave Creek Restoration
The eroding bank was contoured and a 15 feet wide armored bank terrace was constructed to prevent the stream from regaining access to the toe of the slope. We also planted the bank with grass and installed 2 J-hook vanes and one rock vane designed to center the flow toward the channel thalweg.
Throughout the remainder of the project area, we installed an additional cross vane, 4 rootwad complexes and transplanted approximately 6,300 square feet of sod mats and numerous shrub complexes to center the stream flow, increase fisheries habitat pool habitat and complexity, and stabilize stream banks.
We accommodated an existing water right within the project area by installing a flashboard headgate at the point of diversion and a McKay self-cleaning fish screen to eliminate juvenile fish entrainment in the irrigation ditch.
