Over the last decade, this has had a warming effect on lakes. Water clarity is also known to effect water temperature in lakes. What is unclear is how a warming climate might interact with changes in water clarity in lakes. As part of a project at the USGS Office of Water Information, several water clarity scenarios were simulated for lakes in Wisconsin to examine how changing water clarity interacts with climate change to affect lake temperatures at a broad scale. This data set contains the following parameters: year, WBIC, durStrat, max_schmidt_stability, mean_schmidt_stability_JAS, mean_schmidt_stability_July, SthermoD_mean_JAS, SthermoD_mean, lake_average_temp, peak_lake_average_temp, lake_average_temp_JAS, mean_epi_temp, mean_hypo_temp, mean_surf_temp, mean_bottom_temp, peak_surf_temp, peak_bottom_temp, mean_surf_temp_JAS, mean_bottom_temp_JAS, mean_bottom_temp_365, mean_surf_temp_365, mean_1m_temp, mean_surf_JA, GDD_wtr_5c, GDD_wtr_10c, volume_mean_m_3, simulation_length_days, mean_volumetric_temp, kd, out_val calculated for 2210 lakes.

Water temperatures were modeled for 2210 lakes across Wisconsin using the General Lake Model (GLM) between 1979 and 2012 under different scenarios of water clarity change. From these depth-discrete water temperatures, a number of different common metrics of water temperature were calculated at the annual scale. 20121231 Wisconsin Point Point 2210 0.1 0.1 Decimal degrees North American Datum of 1983 Geodetic Reference System 80 6378137.0 298.257 Lake water temperature metrics Calculated lake water temperature metrics derived from a series of model scenarios Producer Defined year The simulated year.
