June 2 2023


Utah has over 100 reservoirs and dams, many of which are used for irrigation, hydroelectric power, and recreation. Major reservoirs in the state include Lake Powell, Flaming Gorge Reservoir, and Strawberry Reservoir. Water for these reservoirs comes from streams and rivers, including the Colorado River and its tributaries, the Green River, and the Provo River. Snowpack from the mountains is a significant source of water for these streams and rivers. Utah experiences a semi-arid climate, with hot summers and cold winters. Drought conditions have been prevalent in recent years, leading to low water levels in some reservoirs. However, record snowfall in 2019 helped to replenish some of these reservoirs. Seasonal trends typically see higher water levels in the spring and early summer due to snowmelt, with levels decreasing in late summer and fall. Overall, reservoirs and dams play a crucial role in managing Utah's water resources and supporting various industries and recreational activities.

Largest Reservoirs

By water storage capacity

The USA is home to many of the largest dams in the world, providing essential services such as water storage, hydropower generation, and flood control. Among them, Oroville Dam stands out as the tallest dam in the United States, located in northern California. Another famous dam is the Hoover Dam, located on the Colorado River between Arizona and Nevada. It is a major tourist attraction and an engineering marvel of the modern era, providing hydropower and water storage for millions of people.

Other notable dams in the USA include the Glen Canyon Dam in Arizona, which is the second-highest concrete arch dam in the country, and the Grand Coulee Dam in Washington, which is the largest electric power-producing facility in the USA. These dams are a critical component of the country's infrastructure, providing essential services for the economy, society, and the environment.

Drought Levels

By water storage capacity

The number and distribution of dams and reservoirs in the USA have been significantly impacted by climate change. The changing climate has led to changes in precipitation patterns, increased evaporation rates, and more frequent and severe droughts and floods in certain regions. These factors have influenced the management and operations of dams and reservoirs across the country.
