USGS Scientific Investigations Report 2013–5014  - Evapotranspiration from Wetland and Open-Water Sites at Upper Klamath Lake, Oregon, 2008

Table 13. Comparison of mean 2008–2010 growing season, non-growing season, and annual evapotranspiration (ET) of alfalfa, pasture, and Upper Klamath Lake NWR wetland, in meters. 

[Alfalfa and pasture growing-season duration and ET determined from Bureau of Reclamation AgriMet Web site. Wetland ET measured using eddy covariance method (this study). Non-growing season alfalfa and pasture ET assumed equal to wetland ET during the same period. Annual ET is the sum of growing season and non-growing season ET. Abbreviation: NWR, National Wildlife Refuge]
