SUMMARY OF VOLUNTEER SURVEY There was no survey response for 1996. FIELD OBSERVATIONS OF ECOLOGY STAFF Two-thirds of the shoreline was lined with lawns and one third with alder, willow and rush. No macrophytes observed during the spring visit. The summer field visit revealed very few macrophytes and a blue-green algal bloom.
TROPHIC STATUS Estimated Trophic State: Oligo-mesotrophic Mean Trophic State Index (Secchi): 36N* (Oligotrophic) Mean Trophic State Index (Total Phosphorus): 30 (Oligotrophic) Mean Trophic State Index (Chlorophyll a): 37 (Oligotrophic) *The calculated TSI is an estimate. The Secchi disk hit bottom (B), entered the weeds (W), or there were too few valid readings (N), or the calculation was based on qualified data (J), or TSIP was based on spring data (S).
SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT Deer Lake is classified as oligo-mesotrophic. Although chemical data suggests an oligotrophic classification, the presence of blue-green algae and hypolimnetic oxygen depletion during the summer sampling is more indicative of an oligo-mesotrophic lake.
COMMENTS FROM 96/09/04 AQUATIC PLANT SURVEY cloudy, light breeze. small swimming mammal, heron, ducks. Most of shoreline with decent riparian area, tho' several bulkheads. Bible camp on west shore. Much bare sediment (sand, gravel, silt), few aquatic plants. Horse pasture by lake at SE end Maximum depth of plant growth: 3.0M.
