Florida, Puerto Rico and the U.S. Virgin Islands

Surface Water

Data and science of streams, rivers, lakes, wetlands and reservoirs

Groundwater

Water in aquifers beneath the earth's surface, a vital source of water supply

Water Quality

Water quality is the suitability of water for a particular use based on selected physical, chemical, and biological characteristics

Caribbean-Florida Water Science Center (CFWSC)

The CFWSC has an active presence in support of hydrologic research and monitoring across the Florida, Puerto Rico, and the U.S. Virgin Islands region.  We look forward to expanding our work with partner organizations throughout this region and identifying new projects of mutual interest relevant to our water-resources.

Sensitivity of the Penman-Monteith reference evapotranspiration equation to meteorological variables for Puerto Rico

Spatiotemporal variations in reference evapotranspiration (ETo) are sensitive to the meteorological data used in its estimation. The sensitivity of the ASCE standardized ETo equation to meteorological variables from GOES-PRWEB dataset was evaluated for the island of Puerto Rico. Island wide, ETo is most sensitive to daily mean relative humidity (RHmean), followed by solar radiation, daily maximum

Field techniques for fluorescence measurements targeting dissolved organic matter, hydrocarbons, and wastewater in environmental waters: Principles and guidelines for instrument selection, operation and maintenance, quality assurance, and data reporting

The use of field deployable fluorescence sensors by the U.S. Geological Survey has become increasingly common for a wide variety of surface water and groundwater investigations. This report addresses field deployable fluorometers that measure the fluorescence response of various substances in water exposed to incident light generated by the sensor. An introduction to the basic principles of field

The water cycle

An illustrated diagram of the water cycle. This is a modern, updated version of the widely used diagram featured on the USGS Water Science School. Notably, this new water cycle diagram depicts humans and major categories of human water use as key components of the water cycle, in addition to the key pools and fluxes of the hydrologic cycle. This product targets an 8th grade audience and is designe

Cyanobacterial bloom in Lake Okeechobee, FL (July 2016)

Lake Okeechobee Sediment Transport Project

Suspended sediment from Lake Okeechobee might be a source of nutrients that helps trigger the growth and development of harmful algal blooms in the Caloosahatchee and St. Lucie Rivers.

Everglades Depth Estimation Network (EDEN) Thumbnail Image

Everglades Depth Estimation Network (EDEN)

In the early 2000s, USGS developed the Everglades Depth Estimation Network (EDEN) to provide water-level data for scientists, decision-makers, and managers to help monitor and assess Everglades restoration. EDEN is a real-time integrated network of 275 water-level gages, water-surface models, and applications that provides 400 x 400 meter gridded daily water-level data across the freshwater part...

Potentiometric Surface of the Upper Floridan Aquifer in the St. Johns River Water Management District and Vicinity, Florida

Due to reduced funding, the May 2009 map will be the last publication of the Potentiometric Surface of the Upper Floridan Aquifer in the St. Johns River Water Management District and Vicinity, Florida unless additional funding sources are identified. Water-level elevations will still be measured semi-annually and published in the Annual Data Report as long as funding is available. The Scientific...
