Summary Consumptive use of water in a dispersed rural community has important implications for maximum housing density and its effects on sustainability of groundwater withdrawals. Recent rapid growth in Colorado, USA has stressed groundwater supplies in some areas, thereby increasing scrutiny of approximate methods developed there more than 30 years ago to estimate consumptive use that are still used today. A foothills residence was studied during a 2-year period to estimate direct and indirect water losses. Direct losses are those from evaporation inside the home, plus any outdoor use. Indirect loss is evapotranspiration (ET) from the residential leach-field in excess of ET from the immediately surrounding terrain....

In 2015, the total amount of water withdrawn for recreational-landscape irrigation uses in Florida was estimated at 398 million gallons per day (Mgal/d). Withdrawals include water used for golf course and public and commercial landscape irrigation (parks, ball fields, highway medians, cemeteries, and other large-scale grass or landscaping areas) that have a consumptive water use permit from the local water management district specifically for golf course or landscape uses. This category does not include individual household lawn irrigation withdrawals. Fresh surface water accounted for 216 Mgal/d of the fresh water withdrawn while 182 Mgal/d was withdrawn from fresh groundwater sources. Palm Beach County accounted...

In 2015, the total amount of water withdrawn for public supply in Florida was estimated at 2,385 million gallons per day (Mgal/d). Water withdrawals include 2,215 Mgal/d of fresh water and 170 Mgal/d of saline water. Fresh groundwater accounted for 1,909 Mgal/d of the water withdrawn and 169 Mgal/d of the saline groundwater withdrawn for public supply. Miami-Dade County accounted for the largest amount of fresh groundwater withdrawn (339 Mgal/d), Hillsborough County accounted for the largest amount of fresh surface water withdrawn (135 Mgal/d) and all of the saline surface water withdrawn (1 Mgal/d), and Lee County accounted for the largest amount of saline groundwater withdrawn (28 Mgal/d). All of the saline water...

Understanding the changes in the distribution and quantity of, and demand for, water resources in response to a changing climate is essential to planning for, and adapting to, future climatic conditions. In order to plan for future conditions and challenges, it is crucial that managers understand the limitations and uncertainties associated with the characterization of these changes when making management decisions. Changes in consumptive water use (water removed without return to a water resources system) will change streamflow, impacting downstream water users, their livelihoods, as well as aquatic ecosystems. Historical changes in available water may be attributed to changes in precipitation; but these changes...
This project applies ET remote sensing at two scales, 1) across the full landscape at 1000 m MODIS resolution (as a component of the water budget to support water availability studies, and 2) on agricultural lands at 100 m Landsat resolution (for estimating crop water use).
The information contained in the following web pages is of a technical nature. It is intended for use by those in the scientific and water resources communities interested in natural flow and salt computations in the Colorado River Basin. These data are furnished by the Bureau of Reclamation for use as hydrologic inputs to the Colorado River Simulation (CRSS) long-term planning and operations model.

In 2015, the total amount of water withdrawn in Florida was estimated at 15,319 million gallons per day (Mgal/d). This includes 9,598 Mgal/d of saline water and 5,721 Mgal/d of fresh water. Water for public supply accounted for the majority of fresh water withdrawn (2,215 Mgal/d) followed closely by agricultural self-supplied (2,089 Mgal/d) for 2015. The remaining fresh water was withdrawn for power generation (434 Mgal/d), commercial-industrial-mining self-supplied (409 Mgal/d), recreational-landscape irrigation (397 Mgal/d), and domestic self-supplied (177 Mgal/d). Water withdrawn for power generation accounted for the majority of saline water withdrawn (9,425 Mgal/d) for 2015, followed by public supply (170...

Water Use by Source and Category in Idaho Counties are compiled as part of the "Estimated Use of Water in the United States" series of U.S. Geological Survey Circular reports that have been published every 5 years since 1950 (Maupin and others, 2014). Idaho withdrawals in 2015 are being published as a separate dataset in support of the U.S. Geological Survey fact sheet 2018-3036. Maupin, M.A., Kenny, J.F., Hutson, S.S., Lovelace, J.K., Barber, N.L., and Linsey, K.S., 2014, Estimated use of water in the United States in 2010: U.S. Geological Survey Circular 1405, 56 p., https://doi.org/10.3133/cir1405.

In 2015, the total amount of water withdrawn for power generation uses in Florida was estimated at 9,859 million gallons per day (Mgal/d). Withdrawals include water used for once-through cooling, cooling pond augmentation, boiler make-up, and domestic uses at power facilities. Saline water accounted for 9,425 Mgal/d of the water withdrawn for power generation, while fresh water accounted for 434 Mgal/d of the water withdrawn for this category. Of the saline water, 9,396 Mgal/d was withdrawn from surface water sources and 29 Mgal/d was withdrawn from groundwater sources. Of the fresh water, 406 Mgal/d was withdrawn from surface water sources and 28 Mgal/d was withdrawn from groundwater sources. Pasco County accounted...
