Data sets of actual evapotranspiration rates from 2000 to 2017 for basins in the Suwannee River Water Management District (SRWMD), calculated using the water-balance method, the bias-corrected Operational Simplified Surface Energy Balance (SSEBop) model, and the land-use crop coefficients model.

Actual evapotranspiration (ETa) rates from the Operational Simplified Surface Energy Balance (SSEBop) method, before and after bias corrections (Sepúlveda, 2021), are presented for basins located wholly or partially within the Suwannee River Water Management District (SRWMD) and parts of Georgia. The SSEBop annual rates are provided at about a one square-kilometer scale from 2000 to 2017. Annual ETa rates calculated from the application of the water-balance method (wbETa) to 6 basins in the SRWMD and annual land-use ETa (luETa) rates calculated from monthly average crop coefficient ratios are also provided in this data set. A GIS shapefile provides land-use type and annual ETa rate for each year of record. Data are tabulated in spreadsheets for each basin and are referred to by the name between parenthesis: Alapaha River basin (Alapaha), Withlacoochee River – SRWMD basin (Withla_SRWMD), Upper Suwannee River basin (Upper_Suwannee), Santa Fe River basin (Santa_Fe), Suwannee River basin (Suwannee_River), and Aucilla River basin (Aucilla). Inflows and outflows from various sources in the water-balance equation used to calculate annual average wbETa rates for each basin in the SRWMD area are presented in this dataset.
