SUMMARY OF VOLUNTEER SURVEY There was no survey response for 1996. FIELD OBSERVATIONS OF ECOLOGY STAFF Lots of surface scum observed during the summer field visit.
TROPHIC STATUS Estimated Trophic State: Oligo-mesotrophic Mean Trophic State Index (Secchi): 36N* (Oligotrophic) Mean Trophic State Index (Total Phosphorus): 35 (Oligotrophic) Mean Trophic State Index (Chlorophyll a): 42 (Mesotrophic) *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 Jumoff Joe Lake is classified as oligo-mesotrophic. TSI and profile data support this classification. There were high concentrations of oxygen throughout the water column.
COMMENTS FROM 97/07/29 AQUATIC PLANT SURVEY Partly cloudy, calm, plants growing at 5 meters. Great plant habitat, diverse community - Chara meadows throughout much of littoral. Many huge goldfish, many turtles, ducks. Maximum depth of plant growth: 5.0M.
