SUMMARY OF VOLUNTEER SURVEY WATER QUALITY----------------------------------------------------------------------- Overall water quality was fair. The worst problems were reported as: 1. algae 2. algae 3. declining long-term trend Sources of actual or potential problems includes: INCREASED LOGGING AND DEVELOPMENT AND OUTDATED SEPTIC SYSTEMS Were there days (and how many) when poor water quality impaired Fishing - YES(60) Swimming - YES(60) Aesthetics - YES(60) MANAGEMENT-------------------------------------------------------------------------- Did the lake receive chemical treatments this year? NO Were fish stocked this year? YES Any lake groups present (such as a lake association)? YES Any lake management activities this year? NO OTHER------------------------------------------------------------------------------- How many homes/new homes are there on the lake shore? 162 Changes since last year? SEVERAL LOTS CLEARED AND DEVELOPED.
FIELD OBSERVATIONS OF ECOLOGY STAFF 5-26-97 Gaylord Kidney wants to do plant surveys. Very few zooplankton observed in the samples. 9-1-97 Lots of boaters which made it difficult to sample
TROPHIC STATUS Estimated Trophic State: Oligo-mesotrophic Mean Trophic State Index (Secchi): 38 (Oligo-mesotrophic) Mean Trophic State Index (Total Phosphorus): 33 (Oligotrophic) Mean Trophic State Index (Chlorophyll a): 41 (Oligo-mesotrophic)
SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT Although nearly all the data collected from Lake Phillips might suggest an oligotrophic lake, there was a significant blue-green algal bloom on the lake this year which is not typical of oligotrophy, therefore, the lake is assessed as oligo-mesotrophic.
COMMENTS FROM 98/07/20 AQUATIC PLANT SURVEY Sunny, light breeze. Shoreline is developed, many bulkheads but also many trees left standing, and many down and submersed. Aquatic plant community sparse and low growing. Much epiphytic algae on substrate and plants in NE end. Observed rough-skinned newts, bullfrog, many small fish. Conducted habitat survey for Kirk Smith. Maximum depth of plant growth: 6.0M.
AQUATIC PLANT LIST (This list may be from multiple years and sources.) Dulichium arundinaceum (Dulichium) Elodea canadensis (common elodea) Iris pseudacorus (yellow flag) Isoetes sp. (quillwort) Juncus sp. (rush) Juncus sp. or Eleocharis sp. (small grass-like plants) Najas flexilis (common naiad) Nitella sp. (stonewort) Potamogeton pusillus (slender pondweed) Utricularia sp. (bladderwort)
