Flooding on the White River near Kadoka, SD, streamgage 06447000. Streamflow at this site was measured by USGS as about 26,000 cubic feet per second on May 18, 2015. Major flooding on the White River in South Dakota occurred in May 2015 following snow and rain events in western South Dakota.

Icy Sampling
RML scientist, Adam Mumford, working under ice to obtain grab samples of a stream in North Dakota to assess impacts of a brine spill from unconventional oil and gas activities (UOG). UOG spills often have very high concentrations of salts, metals, naturally occurring radioactive materials (NORMs), and organic compounds. 

A U.S. Geological Survey hydrologist holds a centrifuge bowl containing river suspended sediment for analysis of metals and organic chemicals. The sample was collected using a new in-field continuous-flow centrifugation technique to separate and collect suspended sediment from large volumes of water.

A U.S. Geological Survey streamflow gaging station collects water data on the Trask River. The Trask River gage is located near Tillamook, Ore. and has been in operation for 17 years.  

Trask River stage, discharge, and water-quality data are collected and used together to help monitor the current health of the river. Data from the river are sent to equipment in the gage house, where it is stored then transmitted to USGS servers.

Both irrigation wells and municipal wells affect water levels in the Little Plover River, Wisconsin. 

Anoxic groundwater pumped from the embayment-uplands aquifers for municipal supply is oxygenated as it cascades over aerator trays. The iron and manganese that are dissolved in the water precipitate and are filtered from the water.
