Jeffrey R. Ziegeweid
Jeffrey Ziegeweid is a Bureau Approving Official in the Office of Science Quality and Integrity.
Jeffrey started working for the U.S. Geological Survey in 2008. Prior to becoming a Bureau Approving Official, Jeffrey held USGS positions as a Hydrologic Technician, Hydrologist, Supervisory Hydrologist, Ecologist, and Hydrologic Reports Specialist. Jeffrey has worked for the Minnesota (2008-18), Upper Midwest (2018-21), and California (2021-2024) Water Science Centers and completed a 120-detail with the Midwest Climate Adaptation Science Center in 2020. Most of Jeffrey’s USGS research focused on the intersection of surface-water hydrology, water quality, and aquatic biology. Prior to joining the USGS, Jeffrey worked in a variety of scientific disciplines and geographic locations, including work experience in the Arctic Circle and a study abroad program in Antarctica.

Chemicals of Emerging Concern and Fish Biological Endpoints Data Collected From Select Tributaries of the St. Croix River, Minnesota and Wisconsin, 2011-12 Chemicals of Emerging Concern and Fish Biological Endpoints Data Collected From Select Tributaries of the St. Croix River, Minnesota and Wisconsin, 2011-12
The U.S. Geological Survey, National Park Service, St. Cloud State University, and the University of St. Thomas conducted a cooperative study to investigate the occurrence of chemicals of emerging concern (CECs) and potential effects to aquatic biota in select tributaries of the St. Croix River in Minnesota and Wisconsin. In 2011, treated wastewater effluent samples were collected from...

Using acoustic Doppler velocity meters to estimate suspended sediment along the lower Minnesota and Mississippi Rivers Using acoustic Doppler velocity meters to estimate suspended sediment along the lower Minnesota and Mississippi Rivers
Lake Pepin is the largest naturally formed lake on the Mississippi River and has complex management needs to satisfy economic, environmental, and cultural demands. Lake Pepin is filling in with sediment at a rapid rate compared to conditions before settlement by European immigrants and intense agricultural cultivation. Accordingly, the Minnesota Pollution Control Agency has developed...

Method comparisons for determining concentrations of metals in water samples used in studies of fish migratory histories Method comparisons for determining concentrations of metals in water samples used in studies of fish migratory histories
Signatures developed from metal concentrations in water and fish bony structures can be used to demonstrate migration of individual fish between connected water bodies. The U.S. Geological Survey (USGS), in cooperation with the National Park Service and the Missouri Department of Conservation, compared two protocols for collecting and analyzing water samples for concentrations of several...

Simulation of hydrodynamics, water quality, and lake sturgeon habitat volumes in Lake St. Croix, Wisconsin and Minnesota, 2013 Simulation of hydrodynamics, water quality, and lake sturgeon habitat volumes in Lake St. Croix, Wisconsin and Minnesota, 2013
Lake St. Croix is a naturally impounded, riverine lake that makes up the last 40 kilometers of the St. Croix River. Substantial land-use changes during the past 150 years, including increased agriculture and urban development, have reduced Lake St. Croix water-quality and increased nutrient loads delivered to Lake St. Croix. A recent (2012–13) total maximum daily load phosphorus...

Water-quality models to assess algal community dynamics, water quality, and fish habitat suitability for two agricultural land-use dominated lakes in Minnesota, 2014 Water-quality models to assess algal community dynamics, water quality, and fish habitat suitability for two agricultural land-use dominated lakes in Minnesota, 2014
Fish habitat can degrade in many lakes due to summer blue-green algal blooms. Predictive models are needed to better manage and mitigate loss of fish habitat due to these changes. The U.S. Geological Survey (USGS), in cooperation with the Minnesota Department of Natural Resources, developed predictive water-quality models for two agricultural land-use dominated lakes in Minnesota—Madison...

Network global navigation satellite system survey to harmonize water-surface elevation data for the Rainy River Basin Network global navigation satellite system survey to harmonize water-surface elevation data for the Rainy River Basin
Continuously recording water-level streamgages in Rainy Lake and Namakan Reservoir are used to regulate water levels according to rule curves established in 2000 by the International Joint Commission; however, water levels at streamgages were referenced to a variety of vertical datums, confounding efforts to model the flow of water through the system, regulate water levels during periods...

Methods to estimate historical daily streamflow for ungaged stream locations in Minnesota Methods to estimate historical daily streamflow for ungaged stream locations in Minnesota
Effective and responsible management of water resources relies on a thorough understanding of the quantity and quality of available water; however, streamgages cannot be installed at every location where streamflow information is needed. Therefore, methods for estimating streamflow at ungaged stream locations need to be developed. This report presents a statewide study to develop methods...
