Assessments

Assessments based on habitat indexes developed by EPA’s National Lake Assessment program.

Habitat Comparisons

Comparison of the average habitat characteristics of sites around GILLETT with the average habitat characteritics at undeveloped and developed sites at other lakes in the state.

Disturbances

Disturbance components that make up the Lakeshore Disturbance score. ‘1.0’ indicates disturbance occurs in the immediate shoreline plot. ‘0.5’ indicates the disturbance occurs in an area proximal to, but not within, the immediate shoreline plot.

Water Quality

Comments: Water level signs of being 8-10” lower than normal. Also signs that level was 2’ higher than normal before dam blew out (sediment on riparian vegetation. Then Also took turbidity at inlets and outlet. Could not see through turbid water to tell area of sed depth and percent cover of algae at inlet 2.

Protection Classification

GILLETT Lake Protection Classification

Comments: Cliffs are in the trees near the outlet.

Could not estimate woody structure and aquatic plant coverage due to the turbidity in the water and the poor water clarity. See notes from site F for aquatic life seen, Elliptio complanata mussels.

Road is the only drawback that gives Gillett a Wilderness Like 8 rating

Site F: Road washed out and into lake with heavy rains. Lake is very turbid/beige brown, lots of newts, damselfly larvae, beetles (whirlygigs), dragonfly larvae, leeches
