DESCRIPTION
CMZ 2 Lower Sleepy Hollow Island Riparian Restoration Project is a riparian restoration and water quality improvement project located on the Lower Wenatchee River a quarter mile south of the Sleepy Hollow Bridge, Chelan County, Washington, Sec. 19 & 20, T23N, R20E.

The project consisted of Bio-engineered Stream Bank stabilization along 790 feet on one side of an actively eroding intermittent channel which did not exist before 1995, (covers about 28.5 acres of earth removed since 1995 - 2300' long x 90' wide x 6' high). Also included is the removal of noxious weeds (Russian olive, Knapweed), and re-establishment of 2.0 acres of native riparian trees, shrubs, and grasses.

This project will improve water quality (temperature and DDT) on the Wenatchee River by reducing erosion which would help prevent continued loss or damage of land, reduce offsite or downstream effects of sediment resulting from bank erosion, and enhance the stream corridor for fish, wildlife habitat and aesthetics with riparian restoration.

In the fall 2010, Cascadia staff oversaw the harvesting and installation of materials for 494 linear feet brush revetment and the restoration of 2.0 acres, with 2,600 willow species and 860 native trees and shrubs of plants. In April 2011, prior to the high water event Cascadia staff oversaw the installation of plant material (1000 willow stakes), irrigation system, and brush revetment maintenance. In the last week of October 2011, Cascadia staff oversaw theinstallation of native trees (100), shrubs (316), work was conducted by WCC. The week of November 14

th the WCC returned to install an additional 296 linear feet of brush revetment and repair a total of 265 linear feet of brush revetment. Approximately, 1800 willow spp. and Red osier dogwood live-stake cuttings (1800) were incorporated into existing and newly constructed brush revetment.
