Equations provided in the Supporting Information for predicting lacustrine sediment organic carbon concentrations, volumetric reservoir sedimentation rates, and for organic carbon burial in lakes/ponds listed incorrect units for land cover variables. Instead of percent (%), they should have been %/100 (as shown below). The correct units were used in all calculations, and the original figures, results, discussions, and conclusions in the paper were not affected by the error. The GLM equation for lacustrine sediment OC concentrations was: sediment OC concentration (%) = 17.170 intercept 0.0013 × soil organic carbon (0−5 cm, g m−2) 19.197 × log wetlands [(%/100) + 1] −26.494 × barren (%/100) −14.098 × k-factor (dimensionless) −1.275 × log water body area (m2) 2.055 (if lake/pond) or −2.055 (if reservoir) The MLR equation for volumetric reservoir sedimentation rates was: log sedimentation rate (m3 yr−1) = −1.520 intercept 0.925 × log surface area (m2) 0.043 × mean slope (degrees) −0.379 × forest (%/100) 0.263 × cultivated crops (%/100) The MLR equation for OC burial rates in lakes/ponds was

log OC burial rate (g C m−2 yr−1) = 0.340 intercept 0.046 × mean annual air temp. (°C) 2.020 × mean k-factor (dimensionless) 0.184 × log soil organic carbon (0−5 cm, g m−2) 0.766 × wetland (%/100) −0.353 × forest (%/100)
