In 1990, vegetation distribution and abundance were studied along five belt transects in Pool 13 of the Upper Mississippi River as part of the Long Term Resource Monitoring Program, with 162 individual site plots sampled on five transects. Using quantitative sampling techniques, 72 plant species were identified. Floodplain forest communities exhibited the highest species diversity, with 61 species represented. Shallow open water communities exhibited the lowest species diversity, with three species represented. Species richness in aquatic habitats was significantly less than in terrestrial habitats. Of the 72 taxa cataloged in 1990 sampling, Acer saccharinum, Vitis riparia, Toxicodendron radicans, and Laportea canadensis...

Resource Trend Analysis water quality and sediment sampling in Upper Mississippi River Pool 13, was initiated in August 1988 as a part of the Long Term Resource Monitoring Program. Mississippi Monitoring Station personnel began water quality sampling on Pool 13 the first week of August using equipment and techniques based on the Procedures Manual for the Long Term Resource Monitoring Program. Over 2600 water quality measurements were made under the Resource Trend Analysis component of the Long Term Resource Monitoring Program on Pool 13 during the sampling period, August 1, 1988 through October 31, 1988. Dissolved oxygen increased throughout the sampling period. Means at channel habitats were slightly higher than...

Resource Trend Analysis water quality sampling in Upper Mississippi River Pool 13 was initiated in August 1988 as a part of the Long Term Resource Monitoring Program. Mississippi Monitoring Station personnel continued water quality sampling in Pool 13 throughout 1989 using equipment and techniques consistent with the Procedures Manual for the Long Term Resource Monitoring Program (LTRMP). A total of 8,382 observations were recorded by the LTRMP water quality component in Pool 13 during the sampling period January 1 through December 31, 1989. Data collected in 1989 reflect water quality characteristics during a second consecutive year of low water conditions. Mean dissolved oxygen (DO) concentrations were higher...
