Ecological health rating
TVA monitored Little Bear Creek Reservoir annually from 1993 to 1997 to establish baseline data on the reservoirs ecological health under a range of weather and flow conditions. Little Bear Creek is now monitored every other year.
Ecological health conditions in Little Bear Creek Reservoir rated poor for the first time in 2005. The reservoir had rated fair all previous years. Ratings for each indicator have generally been consistent from year to year, but the lower score in 2005 was primarily due to lower rating for chlorophyll.

Dissolved oxygen
As in previous years, the lower half of the water column contained little oxygen (less than two milligrams per liter) from June through August. At times during this period, the water on the bottom contained no dissolved oxygen at all.
Chlorophyll
Chlorophyll rated fair as a result of a few elevated chlorophyll concentrations. Chlorophyll levels are typically low in Little Bear, resulting in good ratings for this indicator.
Fish
The fish community rated good. Sampling revealed a good number of species and good catch rate.
Bottom life
Bottom life rated poor because the only animals found in samples collected from the reservoir bottom were species able to tolerate poor water quality conditions.
Sediment
Sediment quality rated good because no pesticides or PCBs were detected and concentrations of metals were within the expected background levels.
