Lake Mead National Park Nevada
Several small to medium-sized islands occur in the lake area depending on the water level. The bathtub ring is white because of the leaching of minerals on previously submerged surfaces. On October 28, Lake Mead hosted the 1st ever B. At lower water levels, a high-water mark or “bathtub ring” is visible in photos that show the shoreline of Lake Mead.

Lloyd Joseph Hudlow, an engineer with the Bureau of Reclamation, came to Boulder City in March to assist in the survey, and ended up as the Project manager.

Lake Mead from space in November North is facing downward to the right. The Colorado River can be seen leading southward away from the lake on the top left. The Hoover Dam is located where the Lake Mead National Park Nevada meets the lake. Nine main access points to the lake are available.
On the west are three roads from the Las Vegas metropolitan area. The lake is divided into several bodies. The large body closest to the Hoover Dam is Boulder Basin. When the lake levels are high enough, a section of the lake farther upstream from the Gregg Basin is flooded, which includes Grand Wash Bay, the Pearce Ferry Bay and launch ramp, and about 55 miles 89 km of the Colorado River within the lower Grand Canyon, extending to the foot of Mile Rapids north of Peach Springs, Arizona.
In addition, two small basins, the Muddy River Inlet and the Virgin River Basin, are flooded when the lake is high enough where these two rivers flow into the lake. As of Februarythese basins remain dry. Jagged mountain ranges surround the lake, offering a scenic backdrop, especially at sunset. Two mountain ranges are within view of the Boulder Basin, the River Mountainsoriented northwest to southeast and the Muddy Mountainsoriented west to northeast.
Bonelli Peak lies to the east of the Virgin Basin. Drought and water usage issues[ edit ] Lake Mead receives the majority of its water from snow melt in the Colorado, Wyoming, and Utah Rocky Mountains. Inflows to the lake are largely moderated by the upstream Glen Canyon Damwhich is required to release 8. Hoover Dam is required to release 9 million acre feet 11, ML of water each year, with the difference made up by tributaries that join the Colorado below Glen Canyon or flow into Lake Mead.
Outflow, which includes evaporation and delivery to Arizona, California, Nevada, and Mexico  from Lake Mead is generally in the range of 9.
From tothe water level fell from 1, to 1, feet to m. During the filling of Lake Powell from tothe water level fell from 1, to 1, feet to m. However, sincethe Colorado River has experienced persistent drought, with average or above-average conditions occurring in only five years—, and in the first 16 years of the 21st century. Although Glen Canyon was able to meet its required minimum release untilthe water level in Lake Mead has steadily declined.
The decreasing water level is due to the loss of the surplus water that once made up for the annual overdraft. Lake Mead as seen from the Hoover Dam with the white band clearly showing the high water level on December 22, Inits record low was 1, Lake Mead’s water level rebounded a few feet by October and avoided triggering the drought restrictions.
