Christie Lake

On the LakeGrade scale Christie Lake grades a B, with clarity at 9.8 ft and 13 µg/L of phosphorus placing it above the Wisconsin median. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

Mesotrophic conditions dominate at Christie Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of just 10 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. The lake's 398 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Christie Lake ranks 59 of 66 in Oconto County — at the lower end of the locally monitored distribution.

Christie Lake has no invasive species recorded in Wisconsin state databases as of 2023, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Christie Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
