With an ever increasing fishing pressure on our natural and artificial lakes every measure possible must be taken to preserve the sport for its many thousands of participants. Hyrum Reservoir is easily accessible to the fishermen of northern Utah. In recent years the lake has offered little in the way of fishing. It is hoped that the information accumulated in this study will help pave the way to a successful stocking program and that Hyrum Reservoir will be one of the productive fishing areas available to Utah anglers. The objectives of this investigation were: 1. To determine the extent of area suitable to fish life at the critical seasons of the year. 2. To determine the chemical, physical and biological factors which may affect fish population numbers. 3. To study critical aspects in the ecology of the rainbow trout in the impoundment.

The distribution of phosphorus in the sediment of Hyrum Reservoir was studied by collecting and analyzing 84 sediment samples for total, inorganic, organic, and water-soluble phosphorus. Sample locations were mapped by triangulation and sediment phosphorus distribution maps were made. Sediment analysis showed average total phosphorus content of 755 micrograms per gram, with organic phosphorus composing approximately 97 percent of total phosphorus. Sediment samples showed variability in phosphorus content which precluded identification of point sources of phosphorus input to the reservoir. Several areas of comparatively higher phosphorus content in the sediments were shown with isopleth maps. An estimate of the extent of sedimentation at each sample site was made. Sediment phosphorus content showed no significant correlation with reservoir sedimentation as determined in this study.

Methods of collecting, concentrating, separating, and identifying organic compounds in natural water systems are presented. These methods were applied to a eutrophic reservoir (Hyrum Reservoir, Utah) and resulted in the identification of the following 27 volatile, organic compounds: Alcohols: methanol, ethanol, 1-propanol, isopropyl alcohol, 1-butanol, 2-butanol, isobutyl alcohol, tert-butyl alcohol, 1-pentanol, 2-methyl-l-butanol, methyl-1- butanol, 3-methyl-2-butanol, 2-methyl-2-butanol, 2-methyl-3-buten-2-ol, 1-penten-3-ol, 2-methyl-2-pentanol Ketones: acetone, methyl ethyl ketone, 4-methyl-3-penten-2-one Aldehydes: acetaldehyde, propanal, 2-buten-1-al Others: acetonitrile, ethyl acetate, pyridine, 3-methylpyridine, diethyl ether The concentration level of the following 13 compounds was established in the reservoir from October 1974 to January 1976: Alcohols: methanol, ethanol, propanol, isopropyl alcohol, 1-butanol, isobutyl alcohol, tert-butyl alcohol 2-methyl-2-butanol, 2-methyl-3-buten-2-ol Ketones: acetone, methyl ethyl ketone Others: acetonitrile, acetaldehyde The highest concentrations of organics were found in the late summer or early fall as the bloom of Aphanizomenon flos-aquae died and the level of bacterial fermentation increased. Other sources of organic compounds in the reservoir (besides fermentation) included compounds (acetonitrile and ethanol) at least partially produced by active algal growth and associated bacteria. Melting snowpack and mountain streams that feed the reservoir also contained organic compounds similar to those found in the reservoir, however at lower levels. Most of the compounds at low concentrations had no effect on the growth of certain algae tested, however there was some indication that certain organics may have increased the net growth of Aphanizomenon flos-aquae.

The current investigation indicates that the routine appearance of a noxious blue-green algal bloom of Aphanizomenon flos-aquae, in Hyrum Lake, a reservoir in northern Utah is a result of excess phosphorus. Data indicate that the algal growth is initiated by phosphorus liberated from the phosphorus rich bottom sediments, and at a time when nitrogen is present in excess in the lake relative to phosphorus. Results indicate that the Little Bear River is the major source of nitrogen and phosphorus contributing to the eutrophication of Hyrum Lake. Nitrogen and phosphorus fluctuations in the Little Bear River proved to be concurrent with nitrogen and phosphorus fluctuations in the reservoir.

The Koyle Relief Mine, located near Spanish Fork in Central Utah, has had a profound effect upon the life and property of thousands of members of the Church of Jesus Christ of Latter-day Saints. Company officials claim that the number of stockholders, past and present, exceeds six thousand persons.Despite the sixty-eight years of its totally unsuccessful operation, the mine continues to maintain a countless number of old believers and to attract a considerable array of new ones. Prompted by a type of religious fervor, these people continue to declare the mine divine and its founder, John H. Koyle, inspired. Basing their faith on the claimed dream, visions, and theophanies of Koyle, they await the coming forth of boundless riches from the mine which will be used to benefit not only themselves, but all of the righteous in the last days.

The Hyrum Project is located in northern Utah near the Cache County seat of Logan, and includes lands bordering the towns of Hyrum, Wellsville, and Mendon, Utah. The primary features of the project include a dam and reservoir on the Little Bear River, and three canals that total slightly more than 20 miles in length. Its principal purpose is to provide supplemental irrigation water to 6,800 acres of fertile land. This project is the result of several investigations relative to the improvement of water utilization in Cache County. A report prepared in 1922 entitled, "Report on the Utilization of the Land and Water Resources of Cache Valley, Utah," stimulated interest and concern over the insufficient water supply. Beginning with this report, and until the final approval of the project in 1933, various county, state, and federal agencies worked together to devise a feasible method of increasing the supply of irrigation water in Cache Valley.

The purpose of this study was to evaluate the effects of boat density on boaters' satisfaction at Hyrum Lake State Park, Utah. The study evaluated relationships between boaters' satisfaction with their Hyrum Lake experience and density of boats at different locations on the lake and among participants in different boating activities. The participants in this study were boaters who used Hyrum Lake between May and September of 1996. An oral, onsite interview survey was randomly given to 282 boaters as they left the lake for the day. The surveys were conducted on high-density days (weekends) and low-density days (weekdays) , which were also randomly selected. Correlation analysis and analysis of variance (ANOVA) were performed . The study found no significant relationships between density and satisfaction associated with either lake location or activity. Satisfaction did not differ between activities; however, participants in two activities (fishing and water skiing) did report higher satisfaction while using the boat ramp than for other locations on the lake. When a Welch t' test was performed comparing boating density ≤ 44 with boating density ≥ 45 boats, even though there was no statistically significant difference, a suggested trend did appear . The results indicate a slightly higher satisfaction rating among water skiers when density was 44 or fewer boats. Conversely, personal watercraft (PWC) users indicated that their satisfaction levels were higher when boating density was ≥ 45 boats. This would suggest that PWC users may be satisfied at boat densities much higher than other users could accept. Although 74% of all the boaters surveyed wanted to set a limit (carrying capacity) on the number of boats allowed on the lake at one time, the carrying capacity will not be immediately implemented, because the data found no statistically significant difference in satisfaction levels with higher boat densities.
