My studies ~'1.ve been qualitative (q'LUUltitntive only in a ver-J general way), rr.ry main purpose beil'1..g to discover and record what insects are present at the different stations during the months of September to June of 1953-54. in ~lich this study has been in progress. Detailed life history studies of the insects \<Jill surely folIo'" by later \'!orkers. Review of literature Dr. J. G. Needham, Professor of Entomology at Cornell University, assisted by R. O. Christenson, collected and classified insects of Logan River in the summer of 1926. Their results (in part) ''Iere published in utah Experiment Station Bulletin 201. Economic Insects in Some Streams of northern Utah. This bulletin has been very useful in my stUdies. More recent collections have been made by Dr. Edmunds at the University of utah, and by Zoology and Wildlife staff menbers and students of the utah state Agricultural College. Dr. G. F. Knowlton, Professor of Entomology at the Utah S~~te Agricultural College, and Fred Harmston, graduate student, collected adult caddice flies and stoneflies in Logan Canyon, which were part of their extensive collections of all 1r..inds of insects in utah. Dr. H. H. Ross of Illinois lTatura1 2 Survey, determined the caddice and stoneflies they collected. But these collections are incomplete and I have found it necessary to seek assistance from specialists at other institutions. Dr. G. F. Edmunds and Dr. A. R. Gaufin, Professors of Biology at the Universi ty of utah. have been most hel:pful, as already acknowledged. Classification of insects in the tmmature. active stages (larvae and nymphs) is even today in a very rudimentary stage; consequently. quite a number of these inseot larvae and nymphs are determined to genus only. The well-known aquatic insects that "'ere found are: ]1phemerlda (mayflies), Plecoptera (stoneflies), Trichontera (caddice flias), Diptera (true flies), Coleoptera (beetles). Hemintera (water boatman), and Odona ta (dragon and damsel f 11 as) • A surv~J of the literature reveals 91 species of aquatic insects collected in or near the river. In this study approxiIJately 44 genera. and 22 s:pecies were collected and classified. Seven are new records. 3 TECIDIH2UE OF COLLECTION In collecting aquatic insects three methods were used: 1. Rand screen. The screen of \nndo,"l wire screen has two hancUes. one on each side. The screen is wider than long (2 x 3 ft.) It "ms used for getting bottom samples of immature insects ~ing on the river bed, hiding beneath the rocks, or attached to boulders. The screen is dipped into the ,~ter by one collector, held against the current ,rl. th handles pushed against the bottom, \<!hile his assistant moves the rocks ,.;1 th his feet or a pick. The current s\'1eeps the insects from their hiding places and lodges them against the screen. They are then lifted and sruucen into a large. white pan, then transferred to preserving bottles. 2. Hand picking. The stones are lifted from the river bottom. set on the banks, and the insects are captured one by one from the roCks, and are transferred to preserving bottles. 3. Nets. The aerial net is used to catch the flying (adult) insects that have recently emerged from the nymph and pupal stages to the air. Some of them perch on the trees or on the "mIls of bridges; those \ole hand pick. The insects are then stored in vials or small bottles containing preservative. A strong. triangular dip net "ms also frequently used. The bottles ,,,ere taken to the laboratory for classi­ fication and storage of the numerous specimens.

  • Cache Valley
    C a c h e V a l l e y V i s i t o r s B u r e a u Cache Valley HERITAGE DRIVING TOUR CACHE VALLEY driving tour Cache Valley extends more than 50 miles into the states of Utah and Idaho. Beautifully nestled among the steep slopes of the Bear River and Wellsville mountain ranges, the valley averages 4500 feet in elevation and is four to twelve miles in width. The surrounding high mountains, clear streams and productive soil all combine to make it a valley rich in the blessings of nature. Cache Valley was the scene of many events important in the settling of the American West. It was here that mountain Indian tribes found ample hunting ground for game, that rugged mountain men splashed through streams in search of beaver, and where Mormon pioneers built new homes in the wilderness of the American frontier. For centuries before the mountain men and the Mormons came to Cache Valley, Native Americans hunted, fished and gathered seeds from the grass that was plentiful upon the valley floor. These Native Americans, the Northwestern Shoshone, named the valley Seuhubeogoi, “Willow River,” and established both winter and summer camps along the major rivers. As nomadic hunters and gatherers they followed centuries-old migratory patterns in search of food. Famous Northwestern Shoshone leaders were Sagwitch, Bear Hunter, Pocatello, Pahvants, and Sanpitch. Mountain men in search of beaver were the first white visitors to Cache Valley. During the years of the Rocky Mountain fur General Merchandise Store, built 1879 Cover photo: American West Heritage Center All photos: USU Special Collections 2 trade, the valley was a crossroad and campground for almost every mountain man who ever fought, trapped or traded in the region.

Dover, U.S. Geological Survey and Philip R. Bigsby, U.S. Bureau of Mines STUDIES RELATED TO WILDERNESS Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and related acts, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe" when the act was passed were incorporated into the National Wilderness Preservation System, and some of them are presently being studied. The act provided that areas under consideration for wilderness designation should be studied for suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. The act directs that the results of such surveys are to be made available to the public and be submitted to the President and the Congress. This report discusses the results of a mineral survey of the Mount Naomi Roadless Area (04758), Wasatch and Caribou National Forests, Cache County, Utah, and Franklin County, Idaho. Mount Naomi Roadless Area was classified as a further planning area during the Second Roadless Area Review and Evaluation (RARE n)i by the U.S. Forest Service, January 1979. MINERAL RESOURCE POTENTIAL SUMMARY STATEMENT Geological, geophysical, and geochemical investigations have been conducted to assess the mineral resource potential of the Mount Naomi Roadless Area (hereafter referred to as "study area"), northeastern Utah and southeastern Idaho.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

  • LOGAN RIVER RESTORATION Conservation Action Plan May 2016
    LOGAN RIVER RESTORATION Conservation Action Plan May 2016 The Logan River, an integral part of the greater Bear River ecosystem, originates within the Bear River Mountains in the headwaters of Logan Canyon and terminates at its confluence with the Little Bear River in Cutler Reservoir. The river is an asset to residents of Logan City and Cache County and has historically supported many beneficial uses. The Logan River was an important resource for Native Americans and pioneers, and it remains valuable today. Cache Valley citizens are attracted to the river and enjoy the aesthetics, recreational values, and wildlife resources associated with this high- quality river, which supports fish, wildlife, and many plant species unique to riparian and wetland habitats. The Logan River also provides water for irrigation, municipal water supply, and hydroelectricity. To protect the Logan River from degradation and the growing threats of floodplain development, a Conservation Action Plan (CAP) has been developed for the portions of the Logan River from First Dam (at the mouth of Logan Canyon) through Cache Valley to the confluence with the Little Bear River at Cutler Reservoir (Figure 1). The development of a short- and long-range vision for the river is needed to coordinate and prioritize conservation efforts and ensure a sustainable river system for future generations. Stakeholder groups representing residential, commercial, recreational, and agricultural interests have participated in the development of this CAP. The CAP is a dynamic set of objectives that can be revised as needed when new threats or conservation solutions are identified. The Logan River CAP uses The Nature Conservancy’s science- based planning framework (further described at https://www.conservatio ngateway.org/Files/Page s/action-planning-cap- handb.aspx) to create a system-wide assessment and plan for the river.
