The effects of highway construction on the fish populations in the Weber River near Henefer, Summit County, UtahPeters, Edward James 19 November 1974 (has links)
Alterations of streams to facilitate highway construction and consumptive water use has become a fisheries management problem. To evaluate the effects of channeling concomitant to construction of Interstate 80 N. near Henefer, Utah, altered and unaltered sections of the Weber River were compared on the basis of fishes censused, population estimates and ordinations. Species compositions in particular areas were influenced by local rheologic conditions. Changes in species composition between samplings at a particular area were caused by fish movements. Data from altered sections, rehabilitated with deflectors and checkdams, were not noticeably different than data from unaltered areas. However, fish movements indicated an unstable environment throughout the study area. This shows that it may be possible to restore channeled streams to productive fisheries.

The effects of channelization and water impoundment on the macroinvertebrates in the Weber River, Summit County, UtahWinger, Parley V. 01 August 1972 (has links)
Macroinvertebrate populations in the Weber River, Summit County, Utah, were analyzed to determine what effects channelization resulting from Interstate-80 construction and water impoundment had on the standing crop, species diversity and species composition. Bottom samples were collected monthly from riffle areas in channeled and unchanneled sections and above Echo and Wanship Reservoirs. Macroinvertebrate populations in the channeled areas were similar in standing crop, species diversity and species composition to those in unchanged areas within six months following channelization. Species diversities were higher (d=4.1, 3.7) above the reservoirs than below (d=2.0). The reservoirs restricted the distribution of several species of macroinvertebrates. The effects of channelization on the macroinvertebrate fauna in the Weber River were negligible, but water impoundment influenced the species composition and species diversities of the populations occurring in the tailwater.

Ghost Water ExhibitionSharp, Michael G. 01 March 2017 (has links)
The Ghost Water exhibition of artworks by Michael Sharp was comprised of four main works titled: 30 x 60 Minute Grid Series, Suspension, History/Prehistory, and Lake Bonneville Remnants. The artwork was created as a reaction to the land that once held the prehistoric Lake Bonneville and to its current remnant Great Salt Lake. The work explores the dialogue between absence and presence.
