In the United States, a nationwide compilation of these metered quantities by the United States Geological Survey (USGS) shows average domestic water deliveries (for both indoor and outdoor purposes) by public water suppliers to single-family and multifamily dwellings were about 89 gallons (337 liters) per person per day in 2010 [4] and 83 ...
The National Map is part of the USGS National Geospatial Program. [3] The geographic information available includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures and land cover. The National Map is accessible via the Web, as products and services, and as downloadable data ...
Although the overall average cost of SWP water is $147 per acre-foot ($119 per 1,000 m 3), agricultural users pay far less than their urban counterparts for SWP water. The Kern County Water Agency (the second largest SWP entitlement holder) pays around $45–50 per acre-foot ($36–41 per 1,000 m 3 ) of SWP water, which is mostly used for ...
California water officials have estimated that the total costs of drinking water solutions for communities statewide amount to $11.5 billion over the next five years.
The NHD is part of the United States Geological Survey The National Map for the United States. The NHD is also linked with similar datasets representing the surface water for Canada and Mexico. The dataset primarily maps features a 1:24,000-scale, but in certain areas provides detail at 1:5,000-scale.
[30] [31] In recent years, budget constraints have forced the USGS to rely on donations of time by civilian volunteers in an attempt to update its 7.5-minute topographic map series, and USGS stated outright in 2000 that the program was to be phased out in favor of The National Map [32] (not to be confused with the National Atlas of the United ...
Aquifers of the United States are organized by national principal aquifer codes and names assigned by the National Water Information System (NWIS). Aquifers are identified by a geohydrologic unit code (a three-digit number related to the age of the formation) followed by a 4 or 5 character abbreviation for the geologic unit or aquifer name. [10]
