Regional regression equations were calculated in Puerto Rico with generalized least squares techniques to estimate flood frequency statistics at ungaged locations using drainage area as the only explanatory variable. The island was divided into 2 regions to minimize residuals. The region division that resulted in lower and more balanced residuals runs primarily north-south near the center of the island, mostly along an 8-digit hydrologic unit code (HUC8) boundary. The division line runs through a HUC8 polygon on the southern end of the island, but care was taken to include entire watersheds and consideration was given where hydrologic and physiographic properties differed. This data release includes geographic information...

Diel studies were conducted at the lake to estimate the community net primary productivity, the respiration rate, and the gross productivity rate. Two diel studies were conducted on November 18, 2010, and May 18, 2011, near the respective annual periods of highest and lowest tides...
Daily evaporation rates were calculated at the open-water LZ40-platform in the interior of Lake Okeechobee, Florida, from December 1, 2012 through December 31, 2016 using five methods (Shoemaker et al., 2024); specifically, the Penman, Priestly-Taylor, Mass-Transfer, Simple, and Turc equations. Bowen-ratio energy-budget derived daily evaporation rates calculated from micro-meteorological data at the LZ40 site (Wacker, 2020) are considered a standard by which to evaluate the five alternative evaporation methods. Parameterization of each of method and comparison of evaporation using each of the five methods to the Bowen ratio estimates are published by Shoemaker and others (2024).

Data pertaining to mapping the approximate inland extent of saltwater at the base of the Biscayne Aquifer in the Model Land Area of Miami-Dade County, Florida in 2016. The inland extent of saltwater at the base of the Biscayne aquifer in the Model Land area of Miami-Dade County, Florida, was last mapped in 2011. Since that time, the saltwater interface has continued to move inland. The interface is near several active well fields; therefore, an updated approximation of the inland extent of saltwater and an improved understanding of the rate of movement of the saltwater interface are necessary. A geographic information system was used to create a map using the data collected by the organizations that monitor water...

This U.S. Geological Survey (USGS) data release consists of evapotranspiration measurements made at the USGS Immokalee row crop climate station beginning September 22, 2008 and ending January 8, 2009. Daily evapotranspiration rates corrected to a near-surface energy-budget varied from 0.1 millimeter (9/28/2008) to 3.3 millimeters (9/24/2008). The eddy-covariance method was used, with high-frequency sensors installed above an experimental field planted in green peppers to measure sensible and latent heat fluxes. Ancillary meteorological data are also included in the data set: net radiation, soil temperature and moisture, air temperature, relative humidity, wind speed and direction, and ground-water level. Data were...
Time series electromagnetic induction-log (TSEMIL) datasets are collected from polyvinyl chloride (PVC) cased or uncased monitoring wells to evaluate changes in water conductivity over time. TSEMIL datasets consist of a series of individual electromagnetic induction logs collected at a frequency of months or years that have been compiled into a dataset by eliminating small uniform offsets in bulk conductivity between logs likely caused by minor variations in calibration. At depths where water conductivity is not changing through time, each log is typically within about ±15 mS/m of the median of the dataset at any given depth, which is within the stated repeatability specifications of the probe (Mount Sopris Instrument...
A groundwater level survey and reconnaissance of the hydrologic conditions in the South Coast aquifer in the Santa Isabel area of southern Puerto Rico was conducted during March 31 to April 17, 2014. The field survey included groundwater level measurements at 55 wells and instantaneous streamflow measurements at 15 locations in streams and irrigation canals. A potentiometric surface map of the alluvial aquifer provides an indication of the directions of groundwater flow. The objective of the field survey was to delineate the potentiometric surface of the study area defined as the South Coast aquifer between the Río Descalabrado to the west and the Río Jueyes to the east of the town of Santa Isabel. Instantaneous...
Periphyton is a complex community of detritus, bacteria, fungi, and algae that grows attached to submerged substrates. Assemblage structure data for algae and cyanobacteria from periphyton samples were collected on a monthly basis from 2017 to 2021. Compiled data were reported as absolute abundance (cells) and biovolume per volume as well as absolute abundance (cells) and biovolume per area at four locations increasing in distance east of the L-67 canal in Water Conservation Area 3 (WCA 3) of the Florida Everglades immediately north of Everglades National Park. The periphyton assemblages were analyzed for five sample types including periphyton plates (Plates), invertebrate inclusion and exclusion plates (Inverts),...

The National Hydrologic Model (NHM) is a modeling framework which has been applied to the continental United States through the Precipitation Runoff Modeling System (PRMS). The PRMS model of Puerto Rico extends the NHM and allows the simulation of rainfall-driven hydrologic conditions in the Commonwealth. Calibration of the NHM Puerto Rico model involved an initial manual calibration to understand the important processes and develop a basic representation of the hydrology. This is followed by an automated calibration procedure using the Let Us CAlibrate (LUCA) multi-objective function model calibration tool. A four-step procedure is used in Luca to separately calibrate parameters for solar radiation, evapotranspiration,...

Annual actual evapotranspiration (ETa) rates in 55 basins in Florida and parts of Alabama and Georgia were evaluated for 2000–17 using the Operational Simplified Surface Energy Balance (SSEBop) model at about a one-square kilometer resolution (Sepúlveda, 2021). SSEBop ETa rates were bias corrected on the basis of ETa rates computed from weather observations at 24 micrometeorological evapotranspiration flux (MEF) stations, stratified by land-use type and referred to as mETa rates. Uncorrected and bias-corrected SSEBop ETa rates were evaluated by comparison with independent estimates based on a crop-coefficient method for generalized land-use types (luETa) and a water-balance method for each basin (wbETa). Average...

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...
