Wetlands Enhancement Study - Jordan Valley Water Conservancy District (JVWCD)

BC&A, with SWCA as a subconsultant, is conducted a Wetland Enhancement Study along the Jordan River Corridor for JVWCD.  The study is designed to help define the impacts to wetlands that may result from developing the shallow aquifer in the Salt Lake Valley as a drinking water source.  The work scope included compiling, evaluating, and development of a geographic information system (GIS) database with pertinent information regarding wetlands and water resources in the area.  A baseline assessment of wetlands along the Jordan River was conducted.  The GIS overlay analysis utilized WAIDS and National Wetlands Inventory (NWI) data, NRCS digital hydric soils data (SSURGO), and recent aerial photography combined with field reconnaissance.  BC&A developed and implemented an exploratory drilling program to install 50 piezometers and 7 stream gauges and monitor water levels in the wetlands and river.  Data collection is still ongoing.  A feasibility assessment of various mitigation measures to eliminate wetlands impacts is being conducted.  Mitigation measures being considered are varying extraction rates, relocating proposed wells to less sensitive areas, providing supplemental water via existing or new canals or pipelines, and wetlands treatment to improve the water quality of return flows to the Jordan River.
