The Oregon Department of State Lands, which has peer review under state law, approved the South County Local Wetlands Inventory (LWI) for the La Pine subbasin on July 19, 2011. The LWI is now officially incorporated into the State of Oregon's wetland inventory database.
The Board of County Commissioners held a hearing on September 26, 2011, deliberated and adopted an ordinance that officially recognizes the LWI in the Comprehensive Plan. The ordinance is effective immediately. This project was funded by grants from the Oregon Watershed Enhancement Board and the Deschutes River Mitigation and Enhancement Program.
