Breaking Down America’s Water Usage

According to the latest USGS data, here’s how Americans use their freshwater:

• Thermoelectric power: 45% (cooling for power plants)
• Irrigation: 32% (agricultural needs)
• Public Supply: 12% (residential and commercial use)
• Industrial: 5% (manufacturing and processing)
• Aquaculture: 3% (fish farming)
• Mining: 2%
• Self-Supplied Domestic: 1% (private wells)

Regional Water Champions

Just twelve states account for more than half of all water withdrawals in the United States. Here’s what makes each state unique:

California (9% of national water use)

• Leading agricultural water consumer
• Faces recurring drought challenges
• According to the Public Policy Institute of California, agriculture accounts for about 80% of all water delivered for human use

Texas (7% of national water use)

• Primarily uses water for power generation
• The major player in groundwater extraction
• The Texas Water Development Board reports that the state’s water demand could increase by 27% by 2070

Idaho (6% of freshwater withdrawals)

• Second-largest irrigation water user nationally
• Leader in aquaculture water use
• The Idaho Department of Water Resources manages over 2 million acres of irrigated farmland

Coastal States and Saline Water

Florida, New York, and Maryland lead in saline water use, primarily for power generation. Florida alone accounts for 23% of all saline water withdrawals nationwide. This highlights an interesting adaptation: using seawater for cooling power plants to preserve freshwater resources.

The Future of Water Use

Current Consumption

• The average American family uses more than 300 gallons of water per day at home (EPA)
• Outdoor water use accounts for 30% of household consumption, mainly for landscape irrigation
• Indoor usage is dominated by toilets (24%), washing machines (22%), and showers (20%)

Looking Ahead

According to the U.S. Government Accountability Office, water managers in 40 states expect water shortages in some portions of their states under average conditions in the next decade. This highlights the growing importance of water conservation and efficient use across all sectors.

Changing Patterns

• Power plants are transitioning to more water-efficient cooling systems, with closed-loop systems reducing water consumption by up to 95% compared to traditional methods
• Farmers are adopting precision irrigation technologies, cutting water usage by 20-50% according to the USDA
• Cities are implementing smart metering and leak detection, with some municipalities reducing water losses by up to 30%

The average annual water bill for households using 60,000 gallons of water a year is $329.06. Privately controlled water systems charge customers an average of $500.96, a 59% increase over the average bill for publicly run water systems, $315.56.

The largest lake in every State located entirely in a single US State

The U.S. has approximately 250 fresh-water lakes known to have surface areas of 13,700 square miles or more. Nearly one hundred are in Alaska, and 100 in Minnesota, Wisconsin, Michigan, New York, and Maine. Thirty-four fresh-water lakes, exclusive of the Great Lakes, have maximum depths of 250 feet or more. Twenty of these are in Alaska, and Alaska unquestionably has more lakes of that depth which have not been sounded. The volume of water stored in natural lakes, even exclusive of the Great Lakes, is much greater than the amount held in artificial reservoirs. Except for the Great Lakes, however, natural lakes’ economic value is surpassed by artificial reservoirs. Natural lakes are best known for the recreational advantages they afford.

Twenty-three U.S. states have all the lakes of 10 square miles or more and numerous smaller lakes. Minnesota has 40 lakes of 10 square miles or more. Michigan has 17 lakes of 10 square miles or more. New York has ten lakes of 10 square miles or more. Washington has three lakes of 10 square miles or more.

The top 20 lakes in size are as listed by the National Atlas of the United States

1. Lake Superior (Michigan, Minnesota, Wisconsin)
   ) – 31,700 sq mi (82,103 km2)
2. Lake Huron (Michigan) – 23,000 sq mi (59,570 km2)
3. Lake Michigan (Illinois, Indiana, Michigan, Wisconsin
   ) – 22,300 sq mi (57,757 km2)
4. Lake Erie (Michigan, New York, Ohio, Pennsylvania
   ) – 9,910 sq mi (25,667 km2)
5. Lake Ontario (New York) – 7,340 sq mi (19,011 km2)
6. Great Salt Lake (Utah) – 2,117 sq mi (5,483 km2)
7. Lake of the Woods (Minnesota) – 1,679 sq mi (4,349 km2)
8. Iliamna Lake (Alaska) – 1,014 sq mi (2,626 km2)

The depth of water each States’s biggest by volume lake creates if evenly distributed over its land

Quick facts:

–  Great Lakes not included because they are too big and skew the geo chart colors too much. Lake Superior would turn Wisconsin into a 71.3 m deep pool.
–  Vermont and Delaware don’t have colors because they were far and away from the deepest and shallowest and skewed the colors too much. This was my first geo chart, I’m learning…
– Did you know Florida is actually the flattest state?
–  Alaska has by far the most lakes of any state. It has over 3 million lakes that don’t have names.

The deepest lake in every U.S. State

The amount of water stored in lakes is enormous compared with the amount held in stream channels at any given time. However, a more significant part of the water stored in lakes is in a few great-sized lakes.

The Great Lakes, which are shared by the U.S. and Canada, hold about 5.5 thousand cubic miles of water. By way of contrast with streamflow, approximately four hundred cubic miles of water, on the average, flows into the ocean from the contiguous U.S every year, only a small part of which would be in temporary storage in the stream channels at any given time. Eight of the deepest known lakes in the conterminous U.S., whose depths vary from 316 feet to 1,932 feet and whose areas exceed 10 square miles Tahoe in California and Nevada, Pend Oreille in Idaho, Chelan in Washington, Crater in Oregon, Champlain in New York and Vermont, Seneca and Cayuga in New York, and Sebago in Maine hold approximately 55 cubic miles of water.

Lake Okeechobee in Florida, although large in surface area, is shallow and probably has less than two cubic miles of water.

The top 20 deepest lakes, according to the National Atlas of the U.S.

1. Crated (Oregon) – 1,932 ft (589 m)
2. Tahoe (California, Nevada) – 1,645 ft (501 m)
3. Chelan (Washington) – 1,605 ft (489 m)
4. Pend Oreille (Idaho) – 1,200 ft (366 m)
