May was an unusually wet month and June was slightly wetter than normal. The rainfall over the past couple of months has kept the lake levels up.
As of this morning Lake Minnehaha, the reference lake for the Clermont Chain, is at 96.53 ft. MSL, slightly below the middle of the regulatory range. The regulatory range is from 96.0 ft. to 97.50 ft. The lake is about 0.36 ft. higher than it was at this same time last year. The combined flow from Big and Little Creeks into Lake Louisa is 32 cfs (cubic ft. per second) or 14,314 gpm (gallons per minute).
