The data consists of daily evaporation measurements/estimates for the time period November 28, 2001 to December 16, 2019. These data are derived from Bowen ratio energy budget computations of actual evaporation based on meteorological and water temperature data at the USGS Reedy Lake evaporation station (USGS station number 282458081364800). This station is located near the center of a lake within the Lake Wales Ridge physiographic province at location 28 degrees 24 minutes 58 seconds North / 081 degrees 36 minutes 48 seconds West within Orange County, Florida. The black water (tannic) lake is crudely circular in shape (minimum and maximum diameters of 750 and 920 meters) and is largely surrounded by forests. The lake is landlocked aside from a possible overflow to the east at high stage. The lake is within sandy terrain composing the surficial aquifer and likely receives discharges of ground water from the aquifer.
