Regional and national monitoring and assessments of streams and rivers: Upper Mississippi, Ohio, and Great Lakes River Basins
Project Number: CRM61
Project Chief: Dan Sullivan
Project Topics: surface water
Cooperators: NAWQA
Period of Project: xxx – Continuing
Objectives
A major focus of the NAWQA Program in its second decade (2002-2012) is on regional- and national-scale assessments of status and trends in streams and rivers. NAWQA has identified eight large geographical regions (referred to as "major river basins") as the basis for its status and trends assessments.
Selected issues to be addressed by major river basins studies include: predictions of nutrient concentrations and loads at unmonitored sites; prediction of pesticide concentrations at unmonitored sites; assessments of pesticide use and trends; and characterization and prediction of stream ecosystem health in wadeable streams.
More information on major river basins studies, including network design and assessments as well as links to publications, can be found at http://water.usgs.gov/nawqa/studies/mrb/
