By: M. Lowe and I. D. Sanderson The U.S. Environmental Protection Agency has recommended that states develop Pesticide Management Plans for four agricultural chemicals - alachlor, atrazine, metolachlor, and simazine - used in Utah as herbicides in the production of corn and sorghum, and...

by Claire Spangenberg Kellner, Rebecca Molinari, Diane Menuz, Peter Goodwin, and Hugh Hurlow Summary Great Salt Lake, the largest saline lake in the Americas, is one of 17 places designated a Western Hemisphere Shorebird Reserve Network, a place of hemispheric importance for migratory birds...

by Trevor H. Schlossnagle and Torri Duncan Summary Rockville is a small rural town in southwestern Utah that is experiencing an increase in residential development. Because potential future septic-tank systems may overlie the principal drinking water aquifer for Rockville, city officials asked the Utah...

By: Greg Gavin, Paul Inkenbrandt, Trevor Schlossnagle, and Rebecca Molinar This comprehensive hydrogeologic assessment of Pahvant Valley's aquifer systems, conducted during 2022-2023, evaluated groundwater storage changes, recharge-discharge relationships, and anthropogenic impacts. The investigation integrated multiple analytical methods including potentiometric surface mapping, InSAR subsidence analysis,...

by Peter Goodwin and Rebecca Molinari Phragmites threaten Great Salt Lake wetlands by readily displacing desirable native vegetation, degrading habitats, and diverting water from the lake and surrounding wetlands through increased evapotranspiration water loss. The Utah Geological Survey (UGS) developed this project with FFSL...

This report presents results and analyses of hydrogeologic, geophysical, groundwater-monitoring, and hydrochemical studies and aquifer tests by the Utah Geological Survey (UGS) in Snake Valley, Tule Valley, and Fish Springs Flat, Millard and Juab Counties, west-central Utah. The primary objectives of this work were...

By: C. T. Sumsion The Spanish Valley area covers about 144 square miles on the western slopes of the La Sal Mountains in southeastern Utah; within it, Spanish Valley comprises about 18 square miles. Altitudes of land surface within the area range from about...

By: David W. Clark, Cynthia L. Appel, Patrick M. Lambert, and Robert L. Puryear The ground-water resources in the East Shore area of Great Salt Lake, Utah, were studied to better define the ground-water system; to document changes in ground-water levels, quality, and storage;...

A hydrologic investigation of Cache Valley was done to better understand the ground-water system in unconsolidated basin-fill deposits and the interaction between ground water and surface water. Ground-water recharge occurs by infiltration of precipitation and unconsumed irrigation water, seepage from canals and streams, and...

Ground-water resources in the Bountiful area, Utah, were studied to document changes in ground-water conditions and to simulate the effects of increased ground-water withdrawals and changes in recharge. The aquifer system is in basin-fill deposits and is primarily a confined system with unconfined parts...

By: C.B. Burden & Others This is the forty-fourth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Department of Natural Resources, Division of Water Resources and...

By: Diane Menuz and Rebekah Downard Wetlands in Utah are regulated primarily by the federal government under the Clean Water Act (CWA), which requires mitigation to replace ecological services that are lost to permitted activities. This report explores the potential for an In-Lieu Fee...

By: Peter Goodwin and Elisabeth Stimmel 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. This project provides an accurate inventory...

By: Peter Goodwin The Scott and Norma Matheson Wetlands Preserve (the Preserve) occupies nearly 900 acres between the Colorado River and the city of Moab, Utah, and encompasses an extensive floodplain-wetland complex that provides several unique functions in the arid west such as recreation, educational...

by Trevor H. Schlossnagle, Janae Wallace, and Nathan Payne This study provides land-use planners with science-based tools for approving new development in a manner that will protect groundwater quality in the communities of Newcastle, Kanarraville, Summit, and Paragonah.
