Landuse Maps and Reports

Detailed land use maps provide valuable data and information on crop types (i.e. cotton, soybeans, rice, etc.), forests, pastures, urban, wetlands and water in the watershed. Louisiana Department of Environmental Quality’s (LDEQ’s) GIS Center worked with LDEQ’s Nonpoint Source (NPS) staff to develop a set of land use maps for watershed planning and implementation. Land use data provides additional information on sources and causes of NPS pollutants in the watershed. If sediment, nutrients and/or bacteria are causing water quality problems, detailed land use maps can indicate which types of crops, pastures or urbanized areas may contribute those pollutants to the water body. Once the types of potential land uses are identified, then management measures (BMPs) can be prioritized for implementation to reduce those pollutants from entering the water body. Water quality monitoring projects can also be designed, based on land use information and suspected sources and causes of NPS pollution. Land use maps and reports on how these maps were developed are available here and copies of land use maps are available for download.
