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. Ten remote sub-basins of the Colorado Plateau in southern Utah and 27 northern Arizona were examined in detail. -

The 13!-minute 16 mm. color-and-sound film will be shown on a large screen in the Las Vegas Convention Center rotunda immediately preceding the President's address. On his way to Las Vegas during his conservation tour, the President will fly over nearby Hoover Dam, pioneer Reclamation multipurpose structure, and its reservoir, Lake Mead, for an aerial inspection. The dam and reservoir, along with Glen Canyon Dam and Lake Powell, 370 miles upstream, are featured in the film. "Clear Water on the Colorado 11 presents spectacular scenes of the once-muddy and almost inaccessible Colorado River in the canyons of Arizona and southern Utah, now desilted and cleared by Glen Canyon Dam which began storing water March 13, 1963. The film portrays the miracle of a silt-free Colorado River between the headwaters of Lake Mead and the headwaters of Lake Powell. The film points out that Glen Canyon Dam--topped out September 13, 1963, has desilted and cleared the Colorado River just as did Hoover Dam downstream 28 years ago. A tremendous load of sediment, varying from 24 to 270 million tons in different years, has been deposited at the head of Lake Mead since Hoover Dam was closed in 1935. -
A Sand Budget for Marble Canyon, Arizona—Implications for Long-Term Monitoring of Sand Storage Change
A Sand Budget for Marble Canyon, Arizona—Implications for Long-Term Monitoring of Sand Storage Change ecent U.S. Geological Survey Rresearch is providing important insights into how best to monitor changes in the amount of tributary- derived sand stored on the bed of the Colorado River and in eddies in Marble Canyon, Arizona. Before the construction of Glen Canyon Dam and other dams upstream, sandbars in Glen, Marble, and Grand Canyons were replenished each year by sediment- rich floods. Sand input into the Colorado River is crucial to protecting endangered native fish, animals, and plants and cultural and recreational resources along the river in Glen Canyon National Recreation Area and Grand Canyon National Park. View of the Colorado River in Grand Canyon, Arizona, showing sandbars that form downstream from There is longstanding interest in tributary debris fans, which constrict the flow of the river and cause eddies.

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.
