This randomization eliminated learning losses found in a previous study. Mean percentage avoidance, the measurement of learning, did not decrease significantly during conditioning trials. Exercised fish learned avoidance better than did non-exercised fish. Mean percentage avoidance for fish exercised at 0.5 ft/sec was 66.3; at 1.0 ft/ sec, 1.5 ft/sec, and …

A Study Of The Effects Of Water Institutions On Planning And Management Of Water Resources In Utah, Donald H. Mclean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One area of research that has been somewhat neglected in water planning programs and water development is that pertaining to water law and water institutions. Over the years each state has developed a complex system of water law and organizations for the allocation and distribution of water. The usual role of these institutions is one of orderly development and the efficient use of the water resource. However, in many cases water law and institutions have imposed serious constraints upon the planning and the most efficient use of a valuable resource.

This study, through historic research, has attempted to define these …
