Stephen Hundt is a hydrologist and modeler with the USGS Idaho Water Science Center in Boise, Idaho.
Stephen is involved in a variety of groundwater and surface water studies throughout Idaho and other Western states. His primary expertise is in developing groundwater flow models as tools to support water resource management. Stephen is also interested in a wide range of hydrology-related topics including uncertainty and data worth assessment, data visualization, and common-pool resource management. Stephen enjoys using Python and R to build reproducible routines for his modeling and analysis tasks.

Groundwater-Flow Model for the Treasure Valley and Surrounding Area
in partnership with the Idaho Department of Water Resources (IDWR) and the Idaho Water Resource Board (IWRB), we are developing a numerical groundwater-flow model of the Treasure Valley and surrounding area. Resource managers will use the model to simulate potential human and climatic effects on groundwater for water-supply planning and management. - Data
Data and archive for a groundwater flow model of the Treasure Valley aquifer system, southwestern Idaho, 1986-2015
This model archive contains the MODFLOW 6 model used to simulate groundwater flow in the Treasure Valley for 1986 through 2015. The simulated results are described in the associated U.S. Geological Survey Professional Paper xxxx. The model archive includes the MODFLOW 6 model, PEST parameter estimation files, and a collection of python scripts that were used to develop the model. The README file dMeasurements of Discharge in Small, Low-Flowing Streams Using Multiple Techniques
The accompanying datasets include all field measurements collected as part of a study to evaluate multiple streamflow measurement techniques in small streams throughout the United States. Each individual dataset is paired with a metadata record describing the contents and purpose of that dataset.Water budget components for hydrologic regions and tribal lands: annual averages 1971-2000
Water budget components for 17 hydrologic regions of the United States which contain tribal lands and for the tribal lands within each of these regions. All values represent an average year based upon the years 1971-2000, and are the result of a combined analysis of national datasets.Compiled Database and Results of the Analysis of Multiple Groundwater-Quality Datasets for Idaho
Groundwater is an important source of drinking and irrigation water throughout Idaho, and groundwater quality is monitored by various Federal, State, and local agencies. The historical, multi-agency records of groundwater quality include a valuable dataset that has yet to be compiled or analyzed on a statewide level. The purpose of this study is to combine groundwater-quality data from multiple so - Publications
Groundwater-flow model of the Treasure Valley, southwestern Idaho, 1986–2015
Most of the population of the Treasure Valley and the surrounding area of southwestern Idaho and easternmost Oregon depends on groundwater for domestic supply, either from domestic or municipal-supply wells. Current and projected rapid population growth in the area has caused concern about the long-term sustainability of the groundwater resource. In 2016, the U.S. Geological Survey, in cooperationAuthorsStephen A. Hundt, James R. BartolinoMapping the probability of freshwater algal blooms with various spectral indices and sources of training data
Algal blooms are pervasive in many freshwater environments and can pose risks to the health and safety of humans and other organisms. However, monitoring and tracking of potentially harmful blooms often relies on in-person observations by the public. Remote sensing has proven useful in augmenting in situ observations of algal concentration, but many hurdles hinder efficient application by end userAuthorsTyler Victor King, Stephen Hundt, Konrad Hafen, Victoria G. Stengel, Scott D DucarEvaluation of select velocity measurement techniques for estimating discharge in small streams across the United States
Multiple instruments and methods exist for collecting discrete streamflow measurements in small streams with low flows, defined here as less than 5.7 m3/s (200 ft3/s). Included in the available methods are low-cost approaches that are infrequently used, in part, because their uncertainty is not well known. In this work, we evaluated the accuracy and suitability of three low-cost velocity measuremeAuthorsTyler Victor King, Stephen Hundt, Amy E. Simonson, Kyle BlaschLaboratory assessment of alternative stream velocity measurement methods
Understanding streamflow in montane watersheds on regional scales is often incomplete due to a lack of data for small-order streams that link precipitation and snowmelt processes to main stem discharge. This data deficiency is attributed to the prohibitive cost of conventional streamflow measurement methods and the remote location of many small streams. Expedient and low-cost streamflow measuremenAuthorsStephen Hundt, Kyle BlaschStreamflow contributions from tribal lands to major river basins of the United States
While many studies on tribal water resources of individual tribal lands in the United States (US) have been conducted, the importance of tribal water resources at a national scale has largely gone unrecognized because their combined totals have not been quantified. Thus, we sought to provide a numerical estimate of major water budget components on tribal lands within the conterminous US and on USGAuthorsKyle Blasch, Stephen Hundt, Patrick Wurster, Roy Sando, Antony BertheloteCompilation and analysis of multiple groundwater-quality datasets for Idaho
