Johnson Canyon (Negro Canyon) Restoration Project
NOE - Notice of Exemption
The Project addresses erosion sites within the Gregory Creek watershed, a tributary to Donner Lake, where past land uses have caused significant drainage alterations and erosion during storm events. Several headcuts have developed in the creek and tributaries, leading to greater erosion. Four locations along Gregory Creek will be targeted to restore the natural hydrologic patterns by decommissioning an abandoned road, re-route a trail, decommissoning old logging landings, and creating new drainage features. The Applicant will install timber and rock check dams, rock drainage crossings, erosion control blanket with willow wattles at top and bottom of slope, and rock-line drainage paths at four sites.
