SUMMARY OF VOLUNTEER SURVEY

WATER QUALITY-----------------------------------------------------------------------
Overall water quality was excellent. No specific problems were listed.
Were there days (and how many) when poor water quality impaired
Fishing - NO(0) Swimming - NO(0) Aesthetics - NO(0)
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)? NO
Any lake management activities this year? NO
OTHER-------------------------------------------------------------------------------
How many homes/new homes are there on the lake shore? 68
Changes since last year? TWO LOTS WERE STRIPPED CLEAR.

FIELD OBSERVATIONS OF ECOLOGY STAFF
5-26-97 There was a fish with a white parasite in the mouth. It was a fluke-shaped
flatworm. Fish was a trout about 10 to 12 inches long. The fish could have been a
stocked fish from this year. About 300 brood stock planted this spring. This was the
first time the volunteer can remember a thermocline. There were some daphnia in the
water samples.

TROPHIC STATUS
Estimated Trophic State: Oligotrophic
Mean Trophic State Index (Secchi): 31 (Oligotrophic)
Mean Trophic State Index (Total Phosphorus): 24 (Oligotrophic)
Mean Trophic State Index (Chlorophyll a): 43 (Mesotrophic)

SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT
Although chlorophyll concentrations suggest a moderately productive lake, all other
indicators suggest a very unproductive lake, therefore, Lake Wooten is assessed as
oligotrophic.

COMMENTS FROM 98/06/16 AQUATIC PLANT SURVEY
Sunny, light breeze. Shoreline mostly developed, large new homes under construction.
Few submersed plants, only in more protected areas with sediment. Algae growing in a
couple of spots that look suspicious - possibly spetic problems? More submersed
plants observed this visit than in 1994.

AQUATIC PLANT LIST (This list may be from multiple years and sources.)
Callitriche stagnalis (pond water-starwort) Carex obnupta (slough
sedge) Carex sp. (sedge) Chara sp. (muskwort) Dulichium

balticus (Baltic rush) Juncus sp. (rush) Ludwigia palustris
(water-purslane) Ludwigia sp. Nitella sp. (stonewort) Nymphaea
