3.6 Riverflow Issues
AFFECTED ENVIRONMENT & ENVIRONMENTAL CONSEQUENCES CHAPTER 3 3.6 RIVERFLOW ISSUES 3.6.1 INTRODUCTION This section considers the potential effects of interim surplus criteria on three types of releases from Glen Canyon Dam and Hoover Dam. The Glen Canyon Dam releases analyzed are those needed for restoration of beaches and habitat along the Colorado River between the Glen Canyon Dam and Lake Mead, and for a yet to be defined program of low steady summer flows to be provided for the study and recovery of endangered Colorado River fish, in years when releases from the dam are near the minimum. The Hoover Dam releases analyzed are the frequency of flood releases from the dam and the effect of flood flows along the river downstream of Hoover Dam. 3.6.2 BEACH/HABITAT-BUILDING FLOWS The construction and operation of Glen Canyon Dam has caused two major changes related to sediment resources downstream in Glen Canyon and Grand Canyon. The first is reduced sediment supply. Because the dam traps virtually all of the incoming sediment from the Upper Basin in Lake Powell, the Colorado River is now released from the dam as clear water. The second major change is the reduction in the high water zone from the level of pre-dam annual floods to the level of powerplant releases. Thus, the height of annual sediment deposition and erosion has been reduced. During the investigations leading to the preparation of the Operation of Glen Canyon Dam Final EIS (Reclamation, 1995b), the relationships between releases from the dam and downstream sedimentation processes were brought sharply into focus, and flow patterns designed to conserve sediment for building beaches and habitat (i.e., beach/habitat-building flow, or BHBF releases) were identified. -

Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics
Effects of the Glen Canyon Dam on Colorado River Temperature Dynamics GEL 230 – Ecogeomorphology University of California, Davis Derek Roberts March 2nd, 2016 Abstract: At the upstream end of the Grand Canyon, the Glen Canyon Dam has changed the Colorado River from a run-of-the-river flow to a deep, summer-stratified reservoir. This change in flow regime significantly alters the temperature regime of the Colorado River. Seasonal temperature variation, once ranging from near to almost , is now limited to 7 . The lack of warm summer temperatures has prevented spawning of endangered 0℃ 30℃ humpback chub in the Colorado River. Implementation of a temperature control device, to − 14℃ allow for warmer summer releases to mitigate negative temperature effects on endangered fish, was considered by the federal government. Ultimately, this proposal was put on indefinite hold by the Bureau of Reclamation and U.S. Fish and Wildlife Service due to concerns of cost and unintended ecological consequences. The low-variability of the current dam-induced Colorado River temperature regime will continue into the foreseeable future. Agencies are reviewing humpback chub conservation efforts outside of temperature control. Keywords: Colorado River, Grand Canyon, Glen Canyon Dam, thermal dynamics 1.0 Introduction Temperature in natural water bodies is a primary driver of both ecological and physical processes. Freshwater plant and animal metabolisms are heavily affected by temperature (Coulter 2014). Furthermore, the thermal structure of a water body has significant impacts on the physical processes that drive ecosystem function (Hodges et al 2000); fluid dynamics drive transport of nutrients, oxygen, and heat. Human action, often the introduction of dams or industrial cooling systems, can alter the natural thermal regimes of rivers and lakes leading to reverberating impacts throughout associated ecosystems. -

Those Glen Canyon Transmission Lines -- Some Facts and Figures on a Bitter Dispute
[July 1961] THOSE GLEN CANYON TRANSMISSION LINES -- SOME FACTS AND FIGURES ON A BITTER DISPUTE A Special Report by Rep. Morris K. Udall Since I came to Congress in May, my office has been flooded with more mail on one single issue than the combined total dealing with Castro, Berlin, Aid to Education, and Foreign Aid. Many writers, it soon became apparent, did not have complete or adequate information about the issues or facts involved in this dispute. The matter has now been resolved by the House of Representatives, and it occurs to me that many Arizonans might want a background paper on the facts and issues as they appeared to me. I earnestly hope that those who have criticized my stand will be willing to take a look at the other side of the story -- for it has received little attention in the Arizona press. It is always sad to see a falling out among reputable and important Arizona industrial groups. In these past months we have witnessed a fierce struggle which has divided two important segments of the Arizona electrical industry. For many years Arizona Public Service Company (APSCO) and such public or consumer-owned utilities as City of Mesa, Salt River Valley Water Users Association, the electrical districts, REA co-ops, etc. have worked harmoniously solving the electrical needs of a growing state. Since early 1961, however, APSCO has been locked in deadly combat with the other groups. Charges and counter-charges have filled the air. The largest part of my mail has directly resulted from a very large, expensive (and most effective) public relations effort by APSCO, working in close cooperation with the Arizona Republic and Phoenix Gazette. -
