Nutrients and Productivity in the Lower Niobrara-Middle Missouri Confluence Area and the 59-mile reach of Missouri River between Gavins Point Dam and Ponca State Park
The Niobrara-Missouri Rivers delta at the head of Lewis and Clark Reservoir and the 59-mile reach of Missouri River below Gavins Point Dam are important river ecosystems for a variety of fish species including paddlefish, sauger, catfish and the endangered pallid sturgeon. From August 2015 through August 2016, we collected nutrient and chlorophyll water samples, and nutrient and carbon bed...
Bioretention Cell Monitoring, Douglas County, Nebraska
USGS Nebraska Water Science Center hydrologists, in cooperation with Douglas County, Nebraska, are monitoring the performance of stormwater bioretention cells that use “green” infrastructure techniques in Omaha, Nebraska. Bioretention cells are used to reduce the quantity of stormwater that flows into a combined sewer overflow (CSO) system which reduces discharge of raw sewage into local streams...
Understanding Cyanobacteria Blooms in the Willow Creek Reservoir
Willow Creek Reservoir is a 700-acre lake in northeast Nebraska. The reservoir has been experiencing frequent harmful algal blooms which pose a health threat to wildlife and humans. The USGS Nebraska Water Science Center has been working with several partners to characterize the algal blooms, investigate possible causes, correlate the algal blooms and possible causes, and deliver the information...
Bioretention Cell Monitoring, Omaha Sewer Maintenance Facility
Stormwater management methodologies are shifting from the traditional storm sewer to a more green-infrastructure approach that stresses the importance of capturing, retaining and treating stormwater. The implementation of green infrastructure uses various Best Management Practices (BMPs) to mitigate the effects of stormwater on flooding and water quality. A bioretention cell is a BMP that captures...
Understanding Sandbar Dynamics in the Lower Platte River
Among the various habitat types within a river corridor, sandbars are highly dynamic and quite sensitive to changes such as channel width, streamflow, and riparian woodland expansion. As people, infrastructure, and other factors encroach upon the Lower Platte River, we are exploring variation in the height and area of sandbars to better accommodate all of these uses without jeopardizing these...
