The Division manages public use and issues a permit for commercial users of the lakebed and shoreline while the Commission facilitates development. The lakebed and surrounding shoreline are made up of State Sovereign Lands. Utah Lake is one of three lakes in the state that were deemed "navigable" at statehood and granted to the State of Utah. Sovereign lands are managed under the public trust doctrine. The Utah State Legislature has designated the Division of Forestry, Fire & State Lands as the executive authority for the management of sovereign lands and the state's mineral estates on lands other than school and institutional trust lands. Sovereign lands are defined by the Utah State Legislature as "those lands lying below the ordinary high water mark of navigable bodies of water at the date of statehood and owned by the state by virtue of its sovereignty." The Commission was created by State statute in Utah's 2007 General Legislative Session

under the authority of th
Interlocal Cooperation Act
The Commission is funded and empowered by 17 area governments, including; Utah County and its municipalities, th
Central Utah Water Conservancy District
and three state agencies. Founded in 2007, the Commission seeks to promote multiple public uses of the lake, facilitate orderly planning and development in and around the lake, and enable individual Commission members to govern their own areas.

counties and then into the southeast portion of the Great Salt Lake. Given the lake's semi-arid climate, large surface area, and shallow average depth, evaporation accounts for 42% of Utah Lake's outflow. After several years of drought, irrigation companies argued over their share of Utah Lake's water from the Jordan River. Judge Morse of the Third District Court issued his judgment known as the Morse Decree of 1901. The decree stated that the irrigation companies "are entitled to a decree awarding to them, subject to the limitations hereinafter set forth, the right to the use of all the balance of the waters of the Jordan River, for municipal, irrigation, culinary, and domestic purposes, to the extent of the capacity of their several canals, and the right to impound and store all of the waters of said river in Utah Lake." In response to the drought, a pumping plant was installed at the outlet of the Jordan River from Utah Lake. It was the largest pumping plant in the United States at the time. The plant contained seven pumps with a total capacity of per second. After the decree was released, Utah Lake essentially became an irrigation reservoir, and the Jordan River's flow was highly regulated. As a result of the 1983–1984 flooding, a lawsuit was filed for compensation due to flooding based upon breach of contract of the previous compromise level. In 1985, a new compromise level was reached, which governed the maximum level of the lake. The new level was chosen to be above sea level. When the water level in Utah Lake exceeds this level, the Jordan River pumps and gates are left open. The new compromise level also meant that the lake's elevation was below Jordan River's stream bed.


Pollution

In 1948, a study showed Utah Lake was being seriously polluted. As a result, Utah County cities decided to plan how and where to build

The Act requires states to identify impaired water bodies every two years and develop a total maximum daily load (TMDL) for pollutants that a body of water can assimilate without causing the water body to exceed the water quality standards. Utah Lake was originally put on Utah's 2000 and 2004 303d list for phosphorus and total dissolved solids (TDS) exceeding recommend values. High levels of phosphorus can cause high levels of nuisance algae growth, low dissolved oxygen, and eleTDS tells about the concentration of mineral salts in the water, which can cause problems to agriculture and culinary water supplies. Excess levels of phosphorus come from multiple sources, but namely the wastewater treatment plants, are extremely concerning when it comes to Utah Lake management because high levels can trigger

Informatics, vol. 34, pp. 129-138, 2016 There is some discussion as to how much of the phosphorus is the result of anthropogenic causes and how much is the result of historic phosphorus stored in the lake sediment. Krissy Wilson of Utah's Division of Wildlife Resources stated in 2010 that water quality is now improving, with greater flows of water, among other things, contributing to the improvement. However, the presence and activity of carp, which stir up solids in the water, makes it difficult to appreciate the improvement without conducting scientific measurements.

History


Pre-European

The first inhabitants of the area were nomadic hunter-gatherers of the Desert Archaic Culture. An archeology site, called the Soo'nkahni Village, has been explored next to the Jordan River in Draper. The site dates back 3,000 years, and over 30,000 artifacts have been found. The next recorded inhabitants were the

who lived in the Utah Lake area from about 400 AD to about 1350 AD. They consisted of small villages of hunters and farmers. They farmed corn, squash, and beans. When climatic conditions changed, they caused trouble for farming. Also, the ancestors to the Ute, Paiute, and Northwestern Shoshone moved into the area. As a result, the Fremont people left the area. The third group inhabited the area was the Utes of central Utah and eastern Colorado. The Timpanogot (also called Timpanogos, Timpanogotzi, Timpannah, and Tempenny) band of the Utes inhabited Utah Valley. They were the most dominant band of Utes due to the relative ease of gathering the plentiful local food supply. It was a sacred meeting place for the Timpanogos, Ute and

Early settlement by members of the Church of Jesus Christ of Latter-Day Saints

The settlement of Utah by members of the Church of Jesus Christ of Latter-Day Saints began in July 1847, when pioneers entered the Salt Lake Valley. Under the direction of Parley P. Pratt, an exploration of Utah Valley was conducted. The party brought a small boat in which they explored Utah Lake and caught fish with their nets. The first battle between settlers and Indians occurred in early March 1849. A company of forty men was sent into Utah Valley to stop the stealing of cattle from the Salt Lake Valley. The company met in the village of Little Chief, who told them where the people responsible for the stealing were located. A skirmish took place in which four Timpanogots were killed. The settlers named the site of the skirmish Battle Creek, which was later renamed Pleasant Grove. In April 1849, a group of about thirty families came into Utah Valley and settled on the Provo River, very close to the main Timpanogot village on the Provo River. The settlers built a

to intimidate the Timpanogots. In August, a Timpanogot named Old Bishop was murdered by three settlers over a shirt they wanted from him. Some Timpanogots shot at cattle or stole corn in response. Winter was especially hard, and Timpanogots stole cattle for food. By January 1850, settlers of Fort Utah reported to officials in Salt Lake City that the situation was getting dangerous. They wanted a military party to attack the Timpanogots. A militia was sent from Salt Lake City, and on February 8 and 11, they engaged the Timpanogots in battle. On February 14, eleven Timpanogots surrendered but were later executed while their families watched. A government surgeon went to the execution site and cut off the Timpanogots' heads for later examination. One militia man and 102 Timpanogots were killed. Over the ensuing years, fewer and fewer Timpanogots lived in Utah Valley, and by 1872, all Timpanogots had moved to the Uintah and Ouray Indian Reservation. However, some Timpanogots occasionally returned to fish on Utah Lake into the 1920s. Captain Howard Stansbury of the United States Army's Corps of Topographical Engineers was ordered to map, survey, and explore Utah and Salt Lake Valleys. In 1850, Captain Stansbury explored Utah Lake and Utah Valley, surveyed and made observation of the local wildlife.

Birds

During the 1800s and the 1930s, killing fish-eating birds were seen as a fish conservation measure. Local government entities gave bounties, and upon presenting evidence of offending dead birds, game officers paid the bounties. A report by a hunter states, "There was a bounty paid on cranes and heron in 1895. Two men could make as high as $66 a day. Wading into the rookeries with their pants off they would crack the heron over the head. When the bounty was paid on pelican we would use a fish float tide to a wad of rushes. Gulls were also caught. There has been 10,000 slaughtered. At the Big Channel gidls have been shot and there are four or five hundred pelicans which have been shot. In 1928 I killed 1,240 mudhens

Parley P. Pratt visited Fort Utah in June 1849 and saw thousands of fish caught by settlers and Timpanogots. He estimated that 5000 barrels of fish could be secured annually from the fishery. The winter of 1885–1886 caused much of the livestock to die. Leaders of

elders sent members in the Salt Lake Valley to Utah Lake to obtain fish; an estimated of fish were brought back. The first commercial fishery also started the same year. At the 1870 General Conference of the LDS Church, a committee was appointed to develop fish culture because of the declining fish harvest in Utah Lake. By 1904, it became illegal to commercially catch any fish except for non-native species. At least 25 species have been introduced into Utah Lake's waters. Thirteen introductions were unsuccessful.

(the Utah Lake sculpin), one is no longer present in the lake and is under review to see if it qualifies for protection under the Endangered Species Act ( least chub), one is already listed as endangered (the June sucker), and one is found in relative abundance throughout Utah (the Utah sucker). All other native fish are no longer extant in the lake. The Bonneville cutthroat trout was historically the top predator fish in the ecosystem but is now restricted to tributary streams. A review in 2008 indicates that viable populations are distributed throughout its historic range and do not merit listing as a threatened or endangered species. The Utah Lake sculpin was last found in 1928 and likely became extinct in the 1930s after severe drought lowered the lake levels, allowing much of the lake to freeze, overcrowding fish in unfrozen portions of the lake. This overcrowding and pollution from agricultural runoff are probable causes of the fish's extinction. The Bonneville redside shiner, mottled sculpin, leatherside chub,

, with an adult population numbering around 7.5 million. The average carp in the lake is about , for a total of nearly of carp in the lake. As early as 1901, fish and wildlife representatives noted that carp were causing the trout population in the lake to collapse. Due to their habit of grubbing through bottom sediments for food, carp stir up sediments and increase the turbidity of the water. In addition, they destroy submerged vegetation that holds sediments in place and provides shelter for native fish populations. Without vegetation, winds can more easily stir up sediment from the bottom of the lake, which is already a problem due to the lake's shallowness, resulting in greater turbidity and less sunlight reaching the remaining vegetation. Without cover for their young, native fish, such as the June sucker, become easy prey for white bass, walleye, and other predators. Efforts are underway to reduce the population of carp in Utah Lake by employing local commercial fishermen, led by Bill Loy, Jr., to remove 5 million pounds of carp each year as part of the June Sucker Recovery Implementation Program's efforts to restore Utah Lake to a habitat in which the June sucker can survive. The intent is to cause a crash in the carp population which will allow the ecosystem to begin to rebuild and the June sucker to reestablish dominance in the lake. The Utah Lake Commission has previously stated its goal is to remove 32 million pounds of carp from the lake, and more than 17 million pounds have been removed as of November 2019.

Legal issues

The ownership of lands along the shoreline of Utah Lake has been in dispute between the State of Utah and farmers for many years. The bed of Utah Lake, along with other natural lakes, was granted to the state upon admission to the Union in 1896. However, due to the lack of an exact definition and significantly fluctuating lake levels, intermittently dry areas, and wetlands, including all of Provo Bay, have been claimed and farmed by surrounding land owners. The U.S.

ruled in 1987 that the State of Utah owned the land beneath Utah Lake. In January 2018, the Utah Department of Natural Resources received a project proposal as a potential solution to the lake's nutrient pollution, invasive species, and murky water. The project proposal involved dredging the lake bottom of all nutrient-loaded sediment, replacing invasive plant and animal species with native species, and restoring the water quality before building and developing housing on arch-shaped islands. The proposal became known as the Utah Lake Restoration project, and had an estimated cost of $6.4 billion which would be obtained through private investors. The proposal led to the creation of the House Bill 272 - Utah Lake Amendments (HB 272), which asserted that Utah Lake faced serious challenges, that conservation and restoration were possible, and in the interest of the state, and authorized "the Division of Forestry, Fire, and State Lands to dispose of state land in exchange for the execution of a project for the comprehensive restoration of Utah Lake," an act which would otherwise be prohibited. On March 21, 2018, Governor Gary Herbert signed HB 272 into law. Critics of the project include ecologists and other scientists raising hydrologic and ecological concerns with the project. Specific issues include the fact that the project would likely lead to the creation of anoxic waters due to lake stratification, the destruction of the lake's unique hydrology and biogeochemistry, the release of toxins and nutrients, altering the lake from its natural state, and geology unsuitable for supporting inhabited islands. Other critics disputed the passing of HB272 as an attempt to trade sovereign lands in exchange for a service. The ability of the developer to maintain the alterations to the lake after the completion of the project has also been brought into question. In October 2022, permitting for the Utah Lake Restoration project was put on hold, according to the

Recovery efforts


June Sucker Recovery Implementation Program (JSRIP)

The June Sucker is a species of fish endemic to Utah Lake and its tributaries. The June Sucker is a key indicator species for the overall health of the ecosystem. Though listed as endangered in 1986 after ecosystem degradation and invasive species concentration, thanks to the efforts of the JSRIP, the June Sucker was downlisted to “threatened” on February 3, 2021. Actions taken to recover the June Sucker include non-native species removal, specifically carp and Northern pike; increasing the population through stocking and monitoring; and restoring and maintaining habitat, including the tributaries Hobble Creek and the Provo River

Since 2014, a large-scale collaborative effort has been underway to mitigate the negative effects of the species through the use of herbicides and crushing techniques. Reports in 2020 indicated a 70% decrease in phragmites.


Utah Lake Water Quality Study (ULWQS)

The purpose of the ULWQS is to gather data on the nutrient concentrations (particularly nitrogen and phosphorus) in Utah Lake and develop nutrient criteria to protect the ecosystem. Phase 1 of the project, Data Gathering, was completed in 2018. Phase 2, Developing Criteria, is currently underway and will be followed by Phase 3, Implementation.
