The proposed project is in Section 22, Township 12 North, Range 1 East, Oklahoma County, Oklahoma.  The project site can be found on the Horseshoe Lake, Oklahoma 7.5 Minute USGS Quadrangle map at North Latitude 35.50279 and West Longitude -97.18030.

The applicant proposes to construct bank stabilization activities along approximately 1,500 linear feet of the left descending bank of the North Canadian River.  The proposed bank stabilization measures includes the construction of bendway weirs (BW), longitudinal peak stone toe protection (LPSTP), and living dikes (LD).

The proposed bank stabilization project would prevent channel migration and preserve the existing water intake for Horseshoe Lake Generating Station.  Currently, there is no protection at this river segment and where it would flow out of this area between Horseshoe Lake and the North Canadian River.  In a large flood event, this could result in extensive erosion at this unprotected bank adjacent to Horseshoe Lake and jeopardize the entire lake system.

The applicant plans to install silt fencing around the work areas, prior to any earth-disturbing activities.  They would install BW and LPSTP, composed of riprap.   Also, the applicant is proposing several LD, consisting of deep planted rows of live un-rooted willow and sycamore trees on the left descending bank.  Rip-rap would be composed of durable well-graded rock sized between 12 to 18-inches, and would be free from dirt, clay, sand, rock fines, and other materials.
