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...

This dataset is a point shapefile containing water-depth points collected during a sedimention survey of Lago Guayabal conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. More than 270,000 water-depth points were surveyed along 60 navigation lines used in previous sedimentation surveys (Soler-Lopez, 2003, 2007, 2008). All water-depth data were collected using a Teledyne-Odom Echotrac CVM depth sounder coupled to a Global Positioning System...

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...

Groundwater withdrawals are published by county and use type every 5 years by the U.S. Geological Survey (http://water.usgs.gov/watuse/) and published values often do not specify the aquifer(s) from which the withdrawals are derived. The items included in this dataset represent estimates of water use by aquifer in the southeastern United States in order to provide better insight into the 3-dimensional distribution of groundwater withdrawals in time and space.

The data set consists of marine seismic-reflection data that includes 34 SEGY data files, navigation data and a CSV format file with a list of files. The archived SEGY files, navigation files, and detailed metadata for these seismic reflections can also be downloaded from the National Archive of Marine Seismic Surveys (NAMSS). https://walrus.wr.usgs.gov/namss//survey/B-1-13-FL/ Marine seismic-reflection data were acquired in canals in eastern Broward County at two different times: February 2010 and April-June 2013, resulting in 34 SEGY data files.

This dataset is a polyline shapefile containing bathymetric contours, at 1-meter intervals, of Lago Guayabal, Villalba, Puerto Rico. The contours were generated from bathymetric data collected during a sedimentation survey conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. Field techniques used during the survey were similar to those outlined by Soler-López (2008) and Wilson and Richards (2006). More than 270,000 water-depth points were surveyed...

A detailed table summarizing the irrigated acreage by crop type and irrigation system was developed for the 2018 growing season (November 2017 and September 2018) for Hillsborough County, Florida. The acreage totals presented are derived from the results of a cooperative project that mapped and field-verified irrigated fields in Hillsborough County, Florida. In addition, the table provides acreage totals by crop type published by the U.S. Department of Commerce for 1978 and 1982 and the U.S. Department of Agriculture for years between 1987 and 2012.

An interdisciplinary and multiagency study was conducted in southern Florida to examine harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains from Lake Okeechobee to the west into the Gulf of Mexico. Using in-situ mesocosm experiments, ammonium, nitrate, phosphate, and urea were altered from ambient conditions to determine the effects on cyanotoxin biosynthesis gene presence and quantity as measured via quantitative polymerase chain reaction (qPCR). Eight experiments were conducted seasonally from May 2019 through July 2021 at the W.P. Franklin Lock and Dam. The experimental installations consisted of three floating metal cradles each containing four opaque fiberglass chambers filled with...

U.S. Geological Survey, in cooperation with Miami-Dade County, performed a sequential, aquifer stress test from August 15 to October 12, 2011, on the Floridan aquifer system at the North District Wastewater Treatment Plant, in Miami-Dade County, Florida. Miami-Dade County stressed the Floridan aquifer system with four municipal injection wells at the North District Wastewater Treatment Plant. Injection wells IW–1, IW–3, and IW–4 stressed the aquifer system with injection of as much as 1.8 cubic meters of effluent per second. Injection well IW–2 stressed the aquifer system with pressure release from the injection zone, caused by reverse flow of as much as 0.04 cubic meters of formation fluid mixed with effluent...
