The dataset includes a table in comma delimited format of daily evapotranspiration (ET) from 6/14/2018 to 12/31/2020 from an ET station within the Blue Cypress Marsh Conservation Area, within Indian River County, Florida. Evapotranspiration was estimated using eddy-covariance methods and missing records were gap-filled with a version of the Turc equation (Trajkovic and Kolakovic, 2009) that was regressed against observed values of eddy-covariance ET. The Turc equation performed exceptionally well (r-squared value of 0.94) for reproducing observed daily ET rates. Daily ET values estimated with the Turc equation are identified by a column with a "T" value indicator. Data processing methods were similar to methods...

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...

Note: This data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P935WRTG. This data release consists of Microsoft Excel workbooks, shapefiles, and a figure (png format) related to a cooperative project between the U.S. Geological Survey (USGS) and the South Florida Water Management District (SFWMD) to derive future change factors for precipitation depth-duration-frequency (DDF) curves at 174 National Oceanic and Atmospheric Administration (NOAA) Atlas 14 stations in central and south Florida. The change factors were computed as the ratio of future (2050-2089) to historical (1966-2005) extreme precipitation depths fitted to extreme precipitation data using a constrained maximum...

The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.5066/P9HK9SSQ), were used to delineate watersheds and develop the peak-flow and low-flow regression equations used by StreamStats.
The primary goal of the Comprehensive Everglades Restoration Plan is to restore natural water flow through the Everglades. An approach known as decompartmentalization, which involves the removal of levees, canals, and other barriers to flow, has been suggested to aid in the restoration. In the region known as Water Conservation Area 3 (WCA-3), the L-67A and L-67C canals and levees, which bisect WCA-3 into WCA-3A to the north and WCA-3B to the south, are major barriers to natural flow. A test project for the decompartmentalization of WCA-3 has been initiated through the WCA-3 Decompartmentalization and Sheetflow Enhancement Physical Model (DPM). This flow-release test involves reconnecting WCA-3A and WCA-3B through...

The dataset includes a table in comma delimited format of daily evapotranspiration (ET) from 6/15/2017 to 1/21/2020 from an ET station in wetlands along the western perimeter of Lake Okeechobee, near Clewiston, Florida. The dominant plant cover at the study site is sawgrass (Cladium jamaicense) with secondary amounts of cattails and open water surfaces such as canals for boat navigation. Sawgrass and cattail height generally varies from less than 1 to 2.4 meters. The depth of water in the wetland averages less than 1 meter above land surface but exceeds 1.5 meters when water levels are high in Lake Okeechobee. In contrast, water levels were less than 1 meter below land surface in the wetland from May to June of...
Estimates of the magnitude of peak-flows were updated for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent chance exceedance levels for 91 rural, unregulated streamgaging stations on the main island of Puerto Rico. These stations required 10 or more years of annual peak-flow record, using data to 2017, for inclusion in the study. The magnitude and frequency of floods at selected streamgages in Puerto Rico were estimated using the U.S. Geological Survey PeakFQ program and updated methods outlined in Bulletin 17C (England and others, 2018). Regional regression equations were calculated to estimate flood frequency statistics at ungaged locations using selected basin characteristics as explanatory variables. These...
The U.S. Geological Survey has compiled information on water withdrawal and use for Puerto Rico at 5-year intervals since 1980 to provide data for the management of the Commonwealth’s water resources. For 2015, water withdrawals and use were estimated for 78 municipalities from fresh groundwater and surface water in the categories of public use, domestic use, irrigation use, livestock, commercial use, industrial use, and mining use and both fresh groundwater and surface water and saline surface-water for thermoelectric power. Fourteen tables and one shapefile were compiled to provide water withdrawals by municipalities and other water use information.

This data set provides the SEAWAT - version 4 model input files used to simulate the transport of the injected fresh wastewater with high levels of ammonia in a saline aquifer in south Florida, from January 1983 to December 2013. Initial conditions for January 1983 are calculated in subdirectory \model\unigrid_link where steady-state conditions are assumed. Files needed to simulate transient conditions from January 1983 to December 2013 are included in the \model\transient sub-directory. Executables needed to read simulated heads, normalized TDS concentrations, and ammonia concentrations from binary output files are provided to assist the user to generate times series of simulated values at each grid cell.

Metadata for this geodatabase describe datasets included in the bathymetric study completed for Lago Patillas in August 2019. The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, carried out a bathymetric survey to update stage-volume table for Lago Patillas and to generate a bathymetric map. Water-depth data were collected using a bathymetric data collection system coupling a digital depth sounder (single-beam fathometer) and a high-quality antenna. Raw water-depth data collected in August 2019 were referenced to the water-surface elevation at the time of the reservoir survey and were merged with light detection and ranging (lidar) cloud data collected in 2016–17. The dataset...
Potential evapotranspiration (PET), and reference evapotranspiration (ETo) are estimated at an approximately 2-kilometer (approximately 0.019 degrees longitude and 0.018 degrees latitude) spatial grid and daily time-scale from January 1, 2019 to December 31, 2019 for the entire State of Florida. PET and ETo were computed on the basis of solar radiation, meteorological data (minimum/maximum temperature, minimum/maximum relative humidity, and mean wind speed at 2-meter height), and shortwave blue-sky albedo data for 2019. Solar radiation was computed from Geostationary Operational Environmental Satellite (GOES) sensor data; blue-sky albedo was computed from the Moderate Resolution Imaging Spectrometer (MODIS) MCD43A1...
