Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell is a reservoir on the
Colorado

Colorado River, straddling the
border between
Utah

Utah and Arizona, United States. Most of Lake Powell,
along with Rainbow Bridge National Monument, is located in Utah. It is
a major vacation spot that around two million people visit every year.
It is the second largest man-made reservoir by maximum water capacity
in the
United States

United States behind Lake Mead, storing 24,322,069 acre feet
(3.0000830×1010 m3) of water when full. However, due to high
water withdrawals for human and agricultural consumption, and because
of subsequent droughts in the area,

Lake Powell is currently larger
than
Lake Mead

Lake Mead in terms of volume of water currently held, depth and
surface area.
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell was created by the flooding of
Glen Canyon

Glen Canyon by the Glen
Canyon Dam, which also led to the creation of
Glen Canyon

Glen Canyon National
Recreation Area, a popular summer destination. The reservoir is named
for explorer John Wesley Powell, a one-armed American Civil War
veteran who explored the river via three wooden boats in 1869. In
1972,
Glen Canyon

Glen Canyon National Recreation Area was established. It is
public land managed by the National Park Service, and available to the
public for recreational purposes. It lies in parts of Garfield, Kane,
and San Juan counties in southern Utah, and Coconino County in
northern Arizona. The northern limits of the lake extend at least as
far as the Hite Crossing Bridge. A map centered at the confluence of

Lake Powell is a water storage facility for the Upper Basin states of
the
Colorado River

Colorado River Compact (Colorado, Utah,
Wyoming

Wyoming and New Mexico).
The Compact specifies that the Upper Basin states are to provide a
minimum annual flow of 7,500,000 acre feet (9.3 km3) to the Lower
Basin states (Arizona, Nevada, and California).

History[edit]
In the 1940s and early 1950s, the
United States

United States Bureau of Reclamation
planned to construct a series of
Colorado River

Colorado River dams in the rugged
Colorado

Colorado Plateau province of Colorado, Utah, and Arizona. Glen Canyon
Dam

Dam was born of a controversial damsite the Bureau selected in Echo
Park, in what is now
Dinosaur National Monument
.jpg/568px-Confluence_of_the_Green_and_Yampa_Rivers_(17396238518).jpg)
Dinosaur National Monument in Colorado. A small
but politically effective group of objectors led by
David Brower

David Brower of
the
Sierra Club

Sierra Club succeeded in defeating the Bureau's bid, citing Echo
Park's natural and scenic qualities as too valuable to submerge. By
agreeing to a relocated damsite near
Lee's Ferry

Lee's Ferry between Glen and
Grand Canyons, however, Brower did not realize what he had gambled
away. At the time, Brower had not actually been to Glen Canyon. When
he later saw
Glen Canyon

Glen Canyon on a river trip, Brower discovered that it
had the kind of scenic, cultural, and wilderness qualities often
associated with America's national parks.[2] Over 80 side canyons in
the colorful
Navajo Sandstone

Navajo Sandstone contained clear streams, abundant
wildlife, arches, natural bridges, and numerous Native American
archeological sites. By then, however, it was too late to stop the
Bureau and its commissioner
Floyd Dominy

Floyd Dominy from building Glen Canyon
Dam. Brower believed the river should remain free, and would forever
after consider the loss of
Glen Canyon

Glen Canyon his life's ultimate
disappointment.[3]

Construction on

Dam began with a demolition blast keyed by
the push of a button by President
Dwight D. Eisenhower

the
Oval Office

Oval Office on October 1, 1956. The first blast started clearing
tunnels for water diversion. On February 11, 1959, water was diverted
through the tunnels so dam construction could begin. Later that year,
the bridge was completed, allowing trucks to deliver equipment and
materials for the dam, and also for the new town of Page, Arizona.
Concrete placement started around the clock on June 17, 1960. The last
bucket of concrete was poured on September 13, 1963. Over 5 million
cubic yards (4,000,000 m³) of concrete make up
Glen Canyon

Glen Canyon Dam. The
Dam

Dam is 710 feet (216 m) high, with the surface elevation of the water
at full pool being approximately 3700 feet (1100 m). Construction of
the
Dam

Dam cost $155 million, and 18 lives were lost in the process. From
1970 to 1980, turbines and generators were installed for
hydroelectricity. On September 22, 1966,
Glen Canyon

Glen Canyon
Dam

Dam was dedicated
by Lady Bird Johnson.

Upon completion of
Glen Canyon

Glen Canyon
Dam

Dam on September 13, 1963, the Colorado
River

River began to back up, no longer being diverted through the tunnels.
The newly flooded
Glen Canyon

Glen Canyon formed Lake Powell. It took 11 years for
the lake to fill to the 3,700 feet (1,100 m) level, on June 22,
1980. The lake level fluctuates considerably depending on the seasonal
snow runoff from the Rocky Mountains.[4][5][6] The all-time highest
water level was reached on July 14, 1983, during one of the heaviest
Colorado River

Colorado River floods in recorded history, in part influenced by a
strong El Niño event. The lake rose to 3,708.34 feet
(1,130.30 m) above sea level, with a water content of 25,757,086
acre feet (31.770898 km3).[7]

Lake Powell and Grand Staircase-Escalante from space, 2016
Colorado River

Colorado River flows have been below average since the year 2000,
leading to lower lake levels. In the winter of 2005 (before the spring
run-off) the lake reached its lowest level since filling, an elevation
of 3,555.10 feet (1,083.59 m)[8] above sea level, which was
approximately 150 feet (46 m) below full pool. Since 2005 the
lake level has slowly rebounded, although it has not filled completely
since then. Summer 2011 saw the third largest June and the second
largest July runoff since the closure of
Glen Canyon

Glen Canyon Dam, and the
water level peaked at nearly 3,661 feet (1,116 m),
77 percent of capacity, on July 30.[9] However, the years 2012
and 2013 were, respectively, the third and fourth-lowest runoff years
recorded on the
Colorado

Colorado River. By April 9, 2014 the lake level had
fallen to 3,574.31 feet (1,089.45 m), largely erasing the gains
made in 2011.[10]
Colorado River

Colorado River levels returned to normal during water years 2014 and
2015 (pushing the lake to 3,606 feet (1,099 m) by the end of
water year 2015[11]), a trend projected to continue in 2016. However,
the Bureau of Reclamation in 2014 reduced the
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell release from
8.23 to 7.48 million acre-feet, for the first time since the lake
filled in 1980. This was done due to the "equalization" guideline
which stipulates that an approximately equal amount of water must be
retained in both
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell and Lake Mead, in order to preserve
hydro-power generation capacity at both lakes. This resulted in Lake
Mead declining to the lowest level on record since the 1930s.

Aerial view on Tower Butte (Arizona)
Glen Canyon

Glen Canyon was carved by differential erosion from the
Colorado

Colorado River
over an estimated 5 million years. The
Colorado

Colorado Plateau, through which
the canyon cuts, arose some 11 million years ago. Within that plateau
lie layers of rock from over 300 million years ago to the relatively
recent volcanic activity. Pennsylvanian and
Permian

Permian formations can be
seen in
Cataract Canyon

Cataract Canyon and San Juan Canyon. The Moenkopi Formation,
which dates from 230 million years ago (Triassic Period), and the
Chinle Formation

Chinle Formation are found at Lees Ferry and the Rincon. Both
formations are the result of the ancient inland sea that covered the
area. Once the sea drained, windblown sand invaded the area, creating
what is known as Wingate Sandstone.
The more recent (Jurassic Period) formations include Kayenta
Sandstone, which produces the trademark blue-black "desert varnish"
that streaks down many walls of the canyons. Above this is Navajo
Sandstone. Many of the arches, including Rainbow Bridge, lie at this
transition point. This period also includes light yellow Entrada
Sandstone, and the dark brown, almost purple Carmel Formation. These
latter two can be seen on the tops of mesas around Wahweap, and the
crown of Castle Rock and Tower Butte. Above these layers lie the
sandstone, conglomerate and shale of the Straight Cliffs Formation
that underlies the
Kaiparowits Plateau

Kaiparowits Plateau and
San Rafael Swell

San Rafael Swell to the
north of the lake.
The confluences of the Escalante, Dirty Devil and San Juan rivers with
the
Colorado

Colorado lie within Lake Powell. The slower flow of the San Juan
river has produced goosenecks where 5 miles (8.0 km) of river are
contained within 1-mile (1.6 km) on a straight line.

The following marinas are accessible only by boat:

Glen Canyon

Glen Canyon National Recreation Area draws more than two million
visitors annually. Recreational activities include boating, fishing,
waterskiing, jet-skiing, and hiking. Prepared campgrounds can be found
at each marina, but many visitors choose to rent a houseboat or bring
their own camping equipment, find a secluded spot somewhere in the
canyons, and make their own camp (there are no restrictions on where
visitors can stay).
The Castle Rock Cut is one of the most important navigational channels
in the lake; it was blasted as early as the 1970s to allow boaters to
bypass the winding canyons between the
Glen Canyon

Glen Canyon
Dam

Dam and reaches of
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell further upstream – saving, on average, one hour of
travel time. The cut has been deepened several times since then, to
allow the use of the channel during droughts.[13] During the
protracted 21st century drought, however, the lake has dropped so
quickly on several occasions that the cut dried up during the summer
tourist season, most recently in 2013. Continued deepening of the
Castle Rock cut has been criticized for its high cost, but boaters and
the
National Park Service

National Park Service argue that it improves safety, saves
millions of dollars in fuel, and improves emergency response time.[14]
Currently most Marinas on the lake don't have Automatic Identification
System monitoring stations that transmit boat positions to the AIS
websites for the boating community. A substantial number of vessels on
the lake do not have AIS transponders as there currently are no
mandatory requirements for AIS usage for this body of water. Extra
precautions must be taken with respect to boating safety, as the
fractal nature of the lake's hydrologic surface area can allow vessels
with limited charting equipment to become easily lost.
The burying of human (and pet) waste in
Glen Canyon

Glen Canyon National
Recreation Area is prohibited. Anyone who camps farther than a quarter
of a mile from a marina, however, must bring a portable toilet. Pet
waste must also be packed out.

Invasive species[edit]
Zebra and quagga mussels first appeared in the
United States

United States in the
1980s.[15]
The mussels were initially brought to the
United States

United States through the
ballast water of ships entering the Great Lakes. These aquatic
invaders soon spread to many bodies of water in the Eastern United
States and have even made their way to the western United States. In
January 2008,[16][17] Zebra mussels have been detected in several
reservoirs along the
Colorado River

Colorado River system such as Lakes Mead, Mojave,
and Havasu.
By the early 2000s Arizona, California, Nebraska, Kansas, Colorado,
Nevada

Nevada and
Utah

Utah have all confirmed the presence of larval zebra
mussels in lakes and reservoirs.
Zebra and quagga mussels can be destructive to an ecosystem due to
competition for resources with native species. The filtration of
zooplankton by the mussels can negatively impact the feeding for some
species of fish. Zebra and quagga mussels can attach to hard surfaces
and build layers on underwater structures. The mussels are known to
clog pipes including those in hydroelectric power systems, thus
becoming a costly and time-consuming problem for water managers in the
West.
Control policies have recently been introduced to alleviate the
hydroelectric problems as well as ecological problems faced by Western
infestation. Beginning in 1999
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell began to visually monitor
for the mussels.
In 2001 hot water boat decontamination sites were established at
Wahweap, Bullfrog, and Halls Crossing marinas. In January 2007, zebra
mussels were detected in
Lake Mead

Lake Mead and new action plans were announced
to prevent the spread of mussels to Lake Powell. In August 2007,
preliminary testing was positive for zebra or quagga larvae in Lake
Powell. These tests were deemed false positives, but adult quagga
mussels were found in 2013.
In August 2010,
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell was declared mussel free. Lake Powell
introduced a mandatory boat inspection for each watercraft entering
the reservoir beginning in June 2009. Effective June 29, 2009, every
vessel entering
Lake Powell
.jpg/500px-Lake_Powell_(2217173388).jpg)
Lake Powell must have a mussel certificate, although
boat owners were allowed to self-certify. These measures were intended
to help prevent vessels from transporting Zebra mussels into Lake
Powell.
Despite these measures, quagga mussel DNA was detected in 2012 and
live mussels were found at a number of sites including the Wahweap
Marina in Spring and Summer 2013. As of June 2013 the NPS was
attempting a diver based eradication program to find and remove
mussels before the lake becomes infested.
