In 2015, the total amount of water withdrawn for recreational-landscape irrigation uses in Florida was estimated at 398 million gallons per day (Mgal/d).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 Fresh surface water accounted for 216 Mgal/d of the fresh water withdrawn while 182 Mgal/d was withdrawn from fresh groundwater sources.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...

File AET2RET_Ratios.csv lists the AET to RET (actual to reference evapotranspiration) ratios, or AET/RET, used to calculate actual evapotranspiration for each land cover type. The daily measured AET data collected at the ET stations were used to calculate the monthly totals for each month of the year. These monthly AET totals were then used to calculate the average AET/RET monthly ratios for the land cover of the ET station by dividing the AET rates by the RET rates obtained from the Florida ET network (http://fl.water.usgs.gov/et/; USGS, 2016). The land cover types represented in these data are forest, grass, marsh, open water, ridge, urban, and agriculture. The AET/RET ratios for these land cover types were presented...

The actual evapotranspiration (AET) annual rates provided in shapefiles AET_SJR_Basin_Cells are for 2 km by 2 km cells in basins in east-central and northeast Florida. The AET rates are presented in the shapefiles for two methods: the Simplified Surface Energy Balance operational (SSEBop) method and for the land-cover type (LC) method. The period of record is 2000 to 2016 for the LC-based method and from 2000 to 2017 for the SSEBop-based method. The SSEBop AET rates are based on a work by Senay and others (2013). The LC-based AET rates were calculated from the AET/RET ratios listed in file AET2RET_Ratios.csv and the annual reference ET rates from 2000 to 2016. A third method used to calculate annual average AET...

In 2016, the total amount of public-supply water withdrawn in Puerto Rico was estimated at 551 million gallons per day (Mgal/d) from fresh water sources. Surface water accounted for 492 Mgal/d (89 percent) and groundwater accounted for 59 Mgal/d (11 percent). Population served by public-supply water systems accounted for 3.4 million people, almost 100 percent of the total population. Total domestic water use was estimated at 396 Mgal/d and it is represented as the summation of deliveries from public-supply water systems to domestic users and self-supplied domestic withdrawals. The average per capita domestic water use, which represents the daily water use for the population that is supplied by public-supply water...

This data release provides data for quantifying the aquatic export of total carbon in a cypress swamp within the Big Cypress National Preserve, and is part of a larger carbon budget study. The U.S. Geological Survey operated two continuous streamflow and water-quality monitoring stations within the Big Cypress National Preserve in southern Florida from September 2015 to October 2017. Site-specific regression models were developed using continuously measured specific conductance and concomitant discretely collected total carbon (dissolved organic carbon, dissolved inorganic carbon, and particulate carbon) samples to calculate continuous concentrations of total carbon. Total carbon loads were calculated by multiplying...

Measured AET monthly rates in file AET_Monthly_Totals.csv were calculated at these ET monitoring stations in central and east-central Florida: Duda Farms, Blue Cypress, Reedy Lake, Orlando Urban, Disney Preserve, Lyonia Preserve. The monthly AET rates measured at these sites are compared side by side with the monthly AET rates calculated using the SSEBop method. The SSEBop AET rates were obtained from Gabriel Senay, one of the authors of Savoca and others, 2013, where the SSEBop methodology is explained. The measured AET monthly rates at the ET sites are presented as another way to assess the reliability of the SSEBop AET rates. The Florida ET network grid pixel numbers used for this comparison are: Duda Farms -...

The U.S. Geological Survey (USGS), in cooperation with Miami-Dade County, mapped the approximate inland extent of saltwater intrusion in eastern Miami-Dade County in 2018. This approximation required acquisition and compilation of relevant data collected by the organizations: Florida Department of Environmental Protection (FDEP), Florida Keys Aqueduct Authority (FKAA), Florida Power & Light Company (FPL), MacVicar Consulting Inc., Miami-Dade County Regulatory and Economic Resources (MD-RER), the South Florida Water Management District (SFWMD), and the USGS. Data from the selected monitoring wells were entered into a geographic information system (GIS) for analysis and mapping. The approximate saltwater interface...

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...

This data release contains the shapefiles and data associated with the assessment of the principal mechanisms affecting the hydrology and water-quality characteristics at Caño Boquerón in Cabo Rojo and at Puerto Mosquito on Isla de Vieques, Puerto Rico. The U.S. Geological Survey, in cooperation with the Puerto Rico Environmental Quality Board (PREQB), conducted a limnological study of these coastal waters to provide baseline information to the regulatory agencies responsible for the management and conservation of these coastal waters and the preservation of their aquatic life. Field measurements and water samples were collected and processed during July 2015–July 2016 for analysis of physical, chemical, biological,...
