The Upper Midwest Environmental Sciences Center of the U.S. Geological Survey and its state partners monitor the aquatic vegetation as well as fish, water quality, and macroinvertebrates in the Upper Mississippi River System. The objective is to accumulate data on aquatic vegetation over a long term using a standardized protocol across the system. The data provide basic information on the vegetation growth within pools for use by resource managers and planners as well as the public for the protection and enhancement of the Upper Mississippi River System. This report summarizes the annual stratified random sampling monitoring results of aquatic vegetation in the Upper Mississippi River System.

In 2003, the format of the annual reports was changed to a Web-based annual update where all years of data are presented in each table. Links to older vegetation status reports are below:

Distribution and frequency of submersed aquatic vegetation in the Upper Mississippi River System are monitored as part of the Long Term Resource Monitoring Program. This report summarizes results of sampling aquatic vegetation along fixed transects in Navigation Pools 4, 8, 13, and 26 in the Upper Mississippi River and La Grange Pool in the Illinois River in 1996. Plants were sampled at regular intervals along fixed transects using a modified rake technique. Sampling was conducted twice during the growing season (spring and summer). Twenty-four submersed and rooted floating-leaved species were found. Most species were found in Pools 4, 8, and 13. Pool 26 had the fewest (3) number of species and Pool 4 had the greatest...

The Upper Midwest Environmental Sciences Center of the U.S. Geological Survey and its state partners monitor the aquatic vegetation as well as fish, water quality, and macroinvertebrates in the Upper Mississippi River System. The objective is to accumulate incremental data on aquatic vegetation over a long term using a standardized protocol across the system. The data provide basic information on the vegetation growth within pools for use by resource managers and planners as well as the public for the protection and enhancement of the Upper Mississippi River System. This report summarizes the annual stratified random sampling monitoring results of aquatic vegetation in the Upper Mississippi River System.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
