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.
