Upper Midwest Water Science Center
Welcome to the Upper Midwest Water Science Center’s (UMid) Website. We offer information on streamflow, water quality, water-use, and groundwater data for Minnesota, Wisconsin and Michigan. We conduct unbiased, scientific hydrologic investigations and research projects to effectively manage the Upper Midwest's and our Nation's water resources through joint efforts with our partners.

Surface variable‐based machine learning for scalable arsenic prediction in undersampled areas Surface variable‐based machine learning for scalable arsenic prediction in undersampled areas
In the United States, private wells are not federally regulated, and many households do not test for Arsenic (As). Chronic exposure is linked with multiple health outcomes, and risk can change sharply over short distances and with well depth. Coarse maps or sparse sampling often miss exceedances. Most existing models operate at ∼1 km resolution and use groundwater chemistry or detailed...
FluOil—A tool for estimating the transport and deposition of oil-particle aggregates in rivers FluOil—A tool for estimating the transport and deposition of oil-particle aggregates in rivers
The FluOil tool was developed to help with planning and early response for oil spills in rivers where subsurface oil-sediment interactions result in the formation of oil-particle aggregates (OPA). The turbulence and variable velocity associated with water flowing within a natural stream channel creates the conditions needed for an oil slick to break up into small droplets and mix in the...
Quantifying leachable phosphorus from the leaves of common midwest urban street trees and implications for stormwater management Quantifying leachable phosphorus from the leaves of common midwest urban street trees and implications for stormwater management
Urban runoff containing high amounts of nutrients like phosphorus (P) is a well-established driver of surface water eutrophication. In residential areas, a primary source of nutrients is derived from leaf litter. P contained in leaves is leached and transported by stormwater from source to stream. The majority of P leached from leaf litter is in the dissolved phase, which can be...
