This 22 failure may result from the contrasting results of base flow studies conducted on the amount of streamflow into the 23 Colorado River sourced from groundwater. Some studies rule out the significance of groundwater contribution, while 24 other studies show groundwater contributing the majority flow to the river. This study uses new and extant 1 25 instrumented data (not indirect methods) to quantify the base flow contribution to surface flow and highlight the 26 overlooked, substantial portion of groundwater.

INTRODUCTION The Paria Canyon - Vermilion Cliffs Wilderness Area contains 112,500 acres (92,500 acres in Coconino County, Arizona and 20,000 acres in Kane County, Utah) of public lands managed by the Bureau of Land Management. The area is approximately 10 to 30 miles west of Page, Arizona. Included are 35 miles of the Paria river Canyon, 15 miles of the Buckskin Gulch, Coyote Buttes, and the Vermilion Cliffs from Lee's Ferry to House Rock Valley (Map 1). The Paria Canyon, Buckskin Gulch, Wire Pass, and the Coyote Buttes Special Management Area are part of the larger Paria Canyon-Vermilion Cliffs Wilderness, designated in August 1984 (Map 2). Existing management plan guidance is to protect primitive, natural conditions and the many outstanding opportunities for hiking, backpacking, photographing, or viewing in the seven different highly scenic geologic formations from which the canyons and buttes are carved. Visitor use in Paria Canyon, Buckskin Gulch, and Coyote Buttes has increased from 2,400 visits in Fiscal Year (FY) 1986 to nearly 10,000 visits in FY96-a 375% increase in use over 10 years. This increased use, combined with the narrow nature of the canyons, small camping terraces, and changing visitor use patterns, is impacting the wilderness character of these areas. Human waste, overcrowding, and public safety have become important issues. -

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.
