GBER_lakesheds
These "lakesheds" are catchment areas for each lake in the GBEBR included in the National Hydrography Dataset lakes. Catchment area was determined with the watershedtool using a pourpoint placed on the cell with the highest flow accumulation value in each lake (from a 10m resolution DEM). Catchment area and lake volume were related (after Brown, 1943) to find a trapping efficency for each lake. Lake depth was assumed to be 2m for all lakes. The fields in this feature's data table are:lake area: (m^2) Lake surface area CW ratio (m^3/km^2) the ratio of the lake capacity and watershed area see Brown, 1943 and Verstraeten and Poesen, 2000)shed_A (m^2) Lake catchment area TE low (%) the trapping efficency using Brown's (1943) lower curveTE high (%) the trapping efficency using Brown's (1943) upper curveautoTE mid (%) the trapping efficency using Brown's (1943) middle curveSubwatershed a subwatershed delineationWatershed Blue Earth, Watonwan or Le SueurBudget_rate a broader subwatershed delineationarcMapA (m^2) the area of the feature
