  • Clear-Water Tributaries of the Colorado River in the Grand Canyon, Arizona: Stream Ecology and the Potential Impacts of Managed Flow by René E
    Clear-water tributaries of the Colorado River in the Grand Canyon, Arizona: stream ecology and the potential impacts of managed flow by René E. Henery ABSTRACT Heightened attention to the sediment budget for the Colorado River systerm in Grand Canyon Arizona, and the importance of the turbid tributaries for delivering sediment has resulted in the clear-water tributaries being overlooked by scientists and managers alike. Existing research suggests that clear-water tributaries are remnant ecosystems, offering unique biotic communities and natural flow patterns. These highly productive environments provide important spawning, rearing and foraging habitat for native fishes. Additionally, clear water tributaries provide both fish and birds with refuge from high flows and turbid conditions in the Colorado River. Current flow management in the Grand Canyon including beach building managed floods and daily flow oscillations targeting the trout population and invasive vegetation has created intense disturbance in the Colorado mainstem. This unprecedented level of disturbance in the mainstem has the potential to disrupt tributary ecology and increase pressures on native fishes. Among the most likely and potentially devastating of these pressures is the colonization of tributaries by predatory non-native species. Through focused conservation and management tributaries could play an important role in the protection of the Grand Canyon’s native fishes. INTRODUCTION More than 490 ephemeral and 40 perennial tributaries join the Colorado River in the 425 km stretch between Glen Canyon Dam and Lake Mead. Of the perennial tributaries in the Grand Canyon, only a small number including the Paria River, the Little Colorado River and Kanab Creek drain large watersheds and deliver large quantities of sediment to the Colorado River mainstem (Oberlin et al.

Agricultural Communications Based on two years of testing, UA School of Renewable Natural Resources researchers have made recommendations for safer use of river water by boaters. Boaters should treat water from the river and its trib- utaries before drinking it. Drinking straight from the river has been common in past seasons. Boaters also should avoid stirring up bottom sediments. The sediments contain much more bacterial contamination than does the surface water. Stirring up sediments, especially in side- stream pools, can raise the fecal bacteria count in water above the stan- dard maximum for body- contact water use.

  • Mules and the Grand Canyon”, a Four Part Series, by Terry Wagner
    IF THEY CAN DO IT AT THE GRAND CANYON THEY CAN DO IT ANYWHERE! By Ben Tennison, Editor In Chief, Western Mule Magazine Our American heritage is in jeopardy today. Who would have believed one of the great icons of our western her - itage, The Grand Canyon Mules would be in jeopardy in our lifetime. Western Mule Magazine broke this news of plans underway to do away with The Grand Canyon Mule trips within the Grand Canyon National Park back in September 2008. Western Mule readers’ response to the article was tremendous, with phone calls, letters and emails to the park service and to government officials. This outcry of in - justice by readers prompted a letter from Park Superintendent Steve Martin himself calling the article erroneous, with only a temporary diversion of mule traffic on the Grand Canyon National Park trails. Steve Martin’s response was published before Superintendent Martin knew who Western Mule Magazine’s source was. We have had no re - sponse from the Park Service since our source was publicly revealed. I have sent along a pdf file of the entire set of articles published in Western Mule Magazine since September 2008 on the Grand Canyon and the famous Grand Canyon Mules. With a tremendous amount of research from Western Mule Magazine contributor, Terry Wagner, these articles will take you where this battle began, through an in depth history of the Grand Canyon and the mules, up to current operations of today. Even though we here at Western Mule Magazine have known of the move to do away with the mules of the Grand Canyon for over a year now, we were of the belief everyone knew about it.

  • Chapter 3 – Affected Environment
    Glen Canyon Dam Long-Term Experimental and Management Plan October 2016 Final Environmental Impact Statement 3 AFFECTED ENVIRONMENT Chapter 3 describes the environmental resources (physical, biological, cultural, recreational, and socioeconomic) that could be affected by the range of alternatives for implementing the Glen Canyon Dam Long-Term Experimental and Management Plan (LTEMP), as described in Chapters 1 and 2. The extent to which each specific resource may be affected by each alternative is discussed in Chapter 4, Environmental Consequences.1 3.1 PROJECT AREA The project area includes the area potentially affected by implementation of the LTEMP (including normal management and experimental operations of Glen Canyon Dam and non-flow actions). This area includes Lake Powell, Glen Canyon Dam, and the river downstream to Lake Mead (Figure 3.1-1). More specifically, the scope primarily encompasses the Colorado River Ecosystem, which includes the Colorado River mainstream corridor and interacting resources in associated riparian and terrace zones, located primarily from the forebay of Glen Canyon Dam to the western boundary of Grand Canyon National Park (GCNP). It includes the area where dam operations impact physical, biological, recreational, cultural, and other resources. This section of the river runs through Glen, Marble, and Grand Canyons in Coconino and Mohave Counties in northwestern Arizona. Although this EIS focuses primarily on the Colorado River Ecosystem, the affected area varies by resources and extends outside of the immediate river corridor for some resources and cumulative impacts. Portions of Glen Canyon National Recreation Area (GCNRA), GCNP, and Lake Mead National Recreation Area (LMNRA) outside the Colorado River Ecosystem are also included in the affected region for certain resources due to the potential effects of LTEMP operations.
