Tim has been a hydrologist with the USGS in Cheyenne, Wyoming, beginning as a student in 1990. He was the National Water Quality Assessment (NAWQA) Yellowstone River Basin Groundwater Specialist from 1997 to 2007. In 2002, Tim was named the Groundwater Specialist for Wyoming, and in 2012 was assigned to be the Groundwater Specialist for Montana as well.
Tim has investigated a wide variety of local (site-specific) and regional (basin or larger) scale groundwater studies. These studies have included both the physical and chemical aspects of hydrogeology, with many integrating both aspects. Detailed characterization of groundwater systems at various scales through the utilization and integration of physical (for example, detailed geologic/lithologic/stratigraphic examination and borehole geophysics) and chemical methods (groundwater chemistry) is of particular interest to Tim.
Tim is recognized for his knowledge of Wyoming’s hydrogeology, and is a licensed Professional Geologist in the state (PG-3349).

Wyoming Landscape Conservation Initiative: Water Resources
The Wyoming Landscape Conservation Initiative is a long-term science-based effort to assess and enhance aquatic and terrestrial habitats at a landscape scale in southwest Wyoming, while facilitating responsible development through local collaboration and partnerships. The WLCI is an interagency working group of partners that is beginning the process of establishing a much larger coalition of...Hydrologic Assessment of the Blackfeet Reservation, Montana
The Blackfeet Nation seeks an increased scientific understanding of the water resources within the Blackfeet Reservation of northwestern Montana. Hydrologic information is needed in order to make informed water management decisions as the Blackfeet Nation moves forward with implementation of the Blackfeet Water Rights Compact as new water-use projects are initiated and as the Blackfeet Irrigation...Williston and Powder River Basins Groundwater Availability Study
The development of two nationally important energy-producing areas, the Williston structural basin (containing the Bakken Formation) and Powder River structural basin, provide a critical opportunity to study the water-energy nexus within a groundwater context. Large volumes of water are needed for energy development in these basins. The hydraulically connected aquifers in the regional glacial...Hydrologic Assessment with an Emphasis on Water Quality within the Lame Deer Creek Watershed, Northern Cheyenne Indian Reservation, Montana
The Lame Deer Creek watershed of the Northern Cheyenne Reservation in southeastern Montana encompasses about 82 square miles and is home to the community of Lame Deer. Local water resources within the Lame Deer Creek watershed include Lame Deer Creek and groundwater within unconsolidated sediments and bedrock aquifers. In 2017 the U.S. Geological Survey, in cooperation with the Northern Cheyenne... - Data
