Wheeler Pond Dam is a masonry structure constructed in the early 1800s. The dam has a maximum height o 20.0 feet and is approximately 54.0 feet long. It is comprised of a 21.0 foot concrete ogee spillway at the left abutment and a 33.0 foot vertical masonry wall at the right abutment. The outlet works at the left abutment is a system of intake chambers and valve pits which withdraw a supply of process water for the adjacent mill complex. Based upon the visual inspection at the site, the lack of engineering back-up data available, and no operational or maintenance evidence, there are areas of concern which must be corrected to assure the long term performance of this dam. The dam is considered to be in fair condition with the following visible signs of concern the inoperable, low-level spillway gate, the poor condition of the mill intake and by-pass chamber and valve pit system now used for the control of water levels in the pond, the obstructed downstream channel and the apparent lack of maintenance of the dam and its appurtenances. A spillway design test flood of 6995 cfs one half of the probable maximum flood will overtop the dam by approximately 6.92 feet.
