Water Budgets

Suspended sediment from Lake Okeechobee might be a source of nutrients that helps trigger the growth and development of harmful algal blooms in the Caloosahatchee and St. Lucie Rivers.

Reservoirs provide most of the water supply for Puerto Rico. Most of them were constructed in the early and middle 20th century and sediment accumulation has significantly reduced their original storage capacity. The U.S. Geological Survey (USGS) has been conducting a series of bathymetric surveys using a global positioning system (GPS) and a geographic information system (GIS) technology on the...

The Floridan Aquifer System (FAS) Groundwater Availability Study (https://fl.water.usgs.gov/floridan/) provides numerous benefits, including an updated hydrogeologic framework, regional and subregional water budgets, and a modern, system-wide, groundwater flow model that may be used to quantitatively assess the effects of human and environmental stresses.

The National Water-Use Information Program of the U.S. Geological Survey (USGS) is a cooperative program designed to compile, store, and disseminate water-use information locally and nationwide. Since 1950, the USGS has compiled data at 5-year intervals on amounts of water used in homes, businesses, and on farms in the United States, and has described how that use changed with time.
