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 GLEN 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.

Comments: inlet 1: near D. inlet 2: stream goes underground (subterranian ecosystem! See J. Deeds) and can’t tell where enters lake. Lots of shale, gravel deposited as delta…Irene 2011? Inlet 3: near E. Inlet 4: Near G - not able to get in close enough for other observations. Inlet 5: Near J - not discernable? Photo of area where supposed to be, near road. Lots of different species, one not in the list: P. ampifolius
