The USGS Nebraska Water Science Center is conducting a pilot study to determine whether sand from the Lewis and Clark Reservoir delta has the desired properties to be used as a proppant in unconventional oil and gas wells that receive hydraulic fracturing (fracking) treatment. Proppants are small particles that are part of the fracking fluid mixture injected into a well to hold open the fractures...

This construction is currently done using a hydraulic dredge to excavate floodplain material. The dredge slurry is discharged into the main channel of the Missouri River. The potential impacts on nutrient and sediment levels in the river from this practice...
