National Wetlands Inventory Maps
The Oklahoma Conservation Commission (OCC) and OWRB cooperated with the Office of the Secretary of the Environment in development of the National Wetlands Inventory (NWI) mapping project. Much of the funding for the project was provided by the Environmental Protection Agency (EPA) under the FY03 104(b)(3) Wetlands Program.
All available NWI digital maps have been obtained from the U.S. Fish & Wildlife Service and can been accessed through the NWI Wetland Map Viewer. Maps are being digitized and will be added to the map viewer upon completion and approval by USFWS. Map availability can be determined by viewing the "NWI Wetlands Status" layer in the viewer. Funding for digitization of the remaining maps was approved by EPA under the FY05 104(b)(3) wetlands program.
Educational components created as a result of this project include:
