Lake Profiles and Tailwater Data

 

Lake temperature and dissolved oxygen profiles are recorded and updated every two weeks during lake stratification (where the heat from the sun causes the water to split into three layers: a warm layer on top, a mixture layer in middle, and a cold layer on bottom), which typically lasts from late spring/early summer to late fall/early winter. The readings are recorded near the dam site on the lake by the lake project staff.  

For tailwater temperatures outside of lake stratification (approx. early winter to late spring), go to Observations of All Lakes

Note to anglers: be advised that fish typically avoid dissolved oxygen levels that are less than 5 mg/L.

Water Quality Gages

In partnership with USGS, the Louisville District Water Quality Team supports several water quality gages.  The data collected by these gages is used by the Team in intensive surveys, special studies, and to evaluate the efficacy of data collection protocols.
