Nitrate in the Illinois River
November 3, 2013 | USGS

Cutting edge optical sensor technology is being used in the Mississippi River basin to more accurately track the nitrate pulse from small streams, large tributaries and ultimately to the Gulf of Mexico.

Old Nitrate and Stream Water Quality
June 16, 2013 | USGS
"USGS hydrologic researchers have found that the movement of nitrate through groundwater to streams can take decades to occur. This long lag time means that changes in the use of nitrogen-based fertilizer — whether the change is initiation, adjustment, or cessation — may take decades to be fully observed in streams." Quoted from the USGS press release.

Connected Consequences of River Dams
January 12, 2014 | USGS
"In a case study of dams on the upper Missouri River, USGS researchers have demonstrated that an upstream dam is still a major control of river dynamics where the backwater effects of a downstream reservoir begin. In light of this finding, the conventional understanding of how a dam can influence a river may have to be adjusted to account for the fact that effects of river dams can interact with one another." Quoted from the USGS press release.
