Available in PDF, EPUB and Kindle. Book excerpt: Six wing dams and an adjacent side channel in Pool 13 of the Upper Mississippi River were studied in the initial phase (pre-notching) of a project to determine the effects of wing dam notching on fish and aquatic community characteristics. Fifty two species of fish were caught in the study area with hoop nets, electrofishing gear, and a small-mesh seine. Thirty eight fish species were caught on or near wing dams. Electrofishing provided the widest variety of fish species and hoop netting provided the least. Electrofishing and hoop net catches were influenced by river stage or discharge. Species composition of the catches changed more dramatically from sampling month to month than between kinds of habitat. Fish were caught in greatest numbers and diversity throughout the study area in August. Discharge varied from month to month and year to year. Water temperature and dissolved oxygen concentration were nearly uniform with depth and among sampling sites each month. Height of wing dams and their position with respect to an upstream bend in the river and to other wing dams influenced current velocity in the study area. Current sweeping over submerged wing dams and over emergent wing dams during high river stages helps prevent sediment accretion between them.

This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 1999, the St. Paul District completed a channel management study for pool 5. An item of investigation in that study was whether channel control structures could be modified to improve aquatic habitat quality without adversely affecting their function in maintaining the navigation channel.

Download or read book Influence of Wing Dam Notching on Aquatic Macroinvertebrates in Pool 13, Upper Mississippi River written by Thomas J. Hall and published by . This book was released on 1980 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Benthic and colonizing macroinvertebrates and physicochemical characteristics were studied at six wing dams and an adjacent side channel in the prenotching phase of a project to determine the effects of wing dam notching on aquatic macroinvertebrates. Water temperature and dissolved oxygen concentration were uniform with depth in each sampling period but varied among periods. Current velocity varied with sampling period because staff gauge, i.e. discharge, varied with time. Current velocity decreased with depth. The substrate was mainly medium sand because bottom current velocities ranged from 22 to 43 cm/s during 1978. Fifty-six taxa of macroinvertebrates were collected with a Ponar grab sampler in 1978. Oligochaeta, the most abundant class, comprised 51% of benthic invertebrate density. Hexagenia bilineata (Say), Hexagenia limbata (Serville), and early instars of Hexagenia spp. made up 64% of the benthic biomass. Total benthic invertebrate, oligochaete, Hexagenia spp., and chironomid density, and biomass and number of benthic taxa each were positively, significantly related to percent silt-clay in the substrate. All of these macroinvertebrate categories were negatively, significantly related to percent sand in the substrate. The wing dams were islands of rock in a sea of sand. Basket samplers collected 26.5 times more macroinvertebrate numbers and 14.3 times more biomass than the Ponar grab sampler made earlier. These differences were related to habitat, i.e. basket samplers collected invertebrates from a lotic-erosional habitat, and the Ponar grab sampler sampled a lotic-depositional habitat.

This book was released on 1982 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large river systems are valuable national resources that provide numerous benefits to travel, shipping, recreation, and fish and wildlife. However, efforts to expand one of the uses frequently come in direct conflict with one or more of the othersThis guide attempts to bring together all scientific data that are available on techniques that have been or can be used to offset or reduce the impacts of development and maintenance of Upper Mississippi River System or other large river systems. Decision makers are thus provided an objective descriptin of options now at their disposal when they attempt to weigh the merits of defects associated with a particular action.

Pool 5, Upper Mississippi River, Buffalo County, Wisconsin and Wabasha and Winona Counties, Minnesota written by and published by . This book was released on 1999-07-01 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to evaluate channel management in pool 5 on the Mississippi River, from Lock and Dam 5 at river mile 738.2 upstream to Lock and Dam no. 4 at river mile 752.8. Study efforts focused on measures to reduce the frequency of dredging problem areas, preventive maintenance, and using dredged material to construct islands habitat purposes. No significant navigation problems were identified aside from channel shoaling in the mid-pool reach. There has been significant decline in fish and wildlife habitat in the lower portion of pool 5 due primarily to loss of islands, sand sediments in backwater habitats, decline in aquatic vegetation and a reduction in bathymetric diversity. The primary restoration measure is the construction of five small islands in lower Belvidere Slough area using channel maintenance dredged material. Wing dam notching will also improve fish habitat.
