Sullivan Lake is located 4.3 miles southeast of Metaline Falls. It is a natural lake that was enlarged by a dam built in Harvey Creek in 1931. The lake is 3.6 miles long and averages 0.6 miles in width. Sullivan Lake drains to Sullivan Creek and the Pend Oreille River. There are campgrounds at both the north and south ends of the lake.

SUMMARY OF VOLUNTEER SURVEY There was no survey response for 1997. FIELD OBSERVATIONS OF ECOLOGY STAFF Lake level in spring was normal, but PUD had been discharging more than usual to keep it that way. Lots of debris on surface and water more turbid than usual this spring. Cool wet summer. Moderate number of small zooplankton in 1-10M summer samples.
TROPHIC STATUS Estimated Trophic State: Oligotrophic Mean Trophic State Index (Secchi): 32N* (Oligotrophic) Mean Trophic State Index (Total Phosphorus): 22 (Oligotrophic) Mean Trophic State Index (Chlorophyll a): 26 (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 Sullivan Lake exhibits all the properties of an oligotrophic lake.
COMMENTS FROM 96/08/01 AQUATIC PLANT SURVEY clear, calm. paddled boat along south shore, walked shore and swam at north end. Only 1 tiny patch of plants at north end, most growing at south end. Most of bottom rocky, plants mostly in water 2-4 m deep. Large bottom fish.
