This report summarizes a recently completed mapping project along the Provo River that covers nearly 33,800 acres of Wasatch and Summit Counties and includes parts of Heber City, Midway, Francis, and Woodland (figure 1). Rapid exurban and suburban development in these areas has replaced historically irrigated agricultural lands causing possible wetland resource conflicts and sparking local concerns about water quality impacts and changes to the rural nature of these communities. The Utah Geological Survey (UGS) developed the project in collaboration with the Utah Division of Wildlife Resources, Wasatch County, and Heber City to provide stakeholders with reliable, accessible wetland mapping data. The project aimed to meet several specific needs: provide an accurate inventory of aquatic habitats along the Middle and Upper Provo River critical for several state sensitive wildlife species and provide local and county officials with accurate wetland locations in rapidly developing areas along Jordanelle Reservoir and in agricultural areas between Heber City and the Provo River. These areas are locally called the North and South Fields, with State Route 113 between Midway and Heber Cities dividing the two areas.

The Utah Geological Survey (UGS) recently updated wetland mapping in Cache County to provide accurate spatial data for responsible urban growth and resource management. The updated mapping identifies wetlands, waterbodies, and riparian areas as part of the National Wetland Inventory (NWI) dataset and includes new, more detailed information. The updated mapping can be viewed on the NWI Wetlands Mapper or the Utah Wetlands Mapper (see Additional Resources).
