Cow Creek Bank Stabilization and Riparian Enhancement Project (Lake or Streambed Alteration Agreement No. 1600-2017-0186-R1)

Cow Creek Bank Stabilization and Riparian Enhancement Project (Lake or Streambed Alteration Agreement No. 1600-2017-0186-R1)

CDFW has executed Lake or Streambed Alteration Agreement No. 1600-2017-0186-R1, pursuant to section 1602 of the fish and game code to Steve Toney. The project is limited to the stabilization and restoration of approx 283 lf of the west bank of Cow Creek. A longitudinal stone toe will be constructed and will measure approx 283 ft long, 10 ft wide at base and five ft tall. Four bendway weirs will be constructed; a 20' long angled upstream 10-15 degrees from the LST, and three 6 ft long weirs. All weirs will be spaced at intervals of approx 60 ft. Each weir will include construction of a tieback behind the LST to prevent stream flows from scouring behind the LST and weirs. These mini-bendway weirs are intended to encourage deposition both upstream and downstream of the barbs and provide substrate complexity over the long term. The area immediately behind the LST will be backfilled using clean, well-graded angular rock as well as cobble, gravel, and sand to allow for riparian plantings. Approx 200-400 willow cuttings ranging from 4-6 ft will be planted to establish erosion protection and enhance riparian vegetation along Cow Creek.
