 | Aquatic vegetation data were collected in the Upper Mississippi River System (UMRS) under the Long Term Resource Monitoring Program (LTRMP). From 1991 to 2002, five reaches were surveyed every year (key pools), and another five reaches were surveyed once (outpools). The study design changed from a protocol involving sampling along transects (1991-2000) to a protocol incorporating stratified random sampling (1998-2002) with concurrent sampling under both protocols in 1998-2000. The frequency ... |

 | Aquatic vegetation was investigated in five navigation pools in the Upper Mississippi River System using a new protocol named 'stratified random sampling' or SRS protocol for the first time in 1998. The five pools were Pools 4, 8, 13, and 26 of the Upper Mississippi River and Us Grange Pool of the Illinois River. The results on submersed aquatic vegetation and rooted floating- leaf aquatic vegetation were summarized in this ... |

|
 | Thirty-two backwaters of the Upper Mississippi and Illinois Rivers were monitored for the eighth consecutive year in 1998 to determine the status and trend of changes of submersed and floating-leaved aquatic vegetation. Aquatic vegetation was sampled at regularly spaced sites along previously established permanent transects. Species compositions, frequencies of individual species, and the frequencies of sites that supported aquatic vegetation in 1998 were calculated and ... |

 | Aquatic vegetation of the Upper Mississippi River System is monitored as part of the long Term Resource Monitoring Program. This report summarizes the 1994 effort of monitoring submersed aquatic vegetation (SAV) along transects permanently established in vegetated locations within four navigation pools of the Upper Mississippi River and one navigation pool of the Illinois River. A total of 17 species of SAV were found along transects during ... |
