"The present run-of-the-river dam is approximately 390 feet long. It consists of a straight section (ca. 1911) about 190 feet long and 10 feet high, which blocks the main flow of the stream. This portion of the structure shows signs of four different construction phases as evidenced by obvious seams and joints on its downstream face. This dam replaced a log crib dam (apparently a crib and deck overflow type - ca. 1867) which itself replaced what is reputed to have been an old rubble or coffer dam (ca. 1840). The so-called "steps" at the east end of this portion were a retaining wall for the current dam and its precedent log dam, but after a portion of the wall washed out in a flood (1919), the resultant widening of the river damaged the bridge and forced construction of the present east curved portion of the dam (ca. 200 feet in length). There was more damage the next year requiring the dam to be extended into the east river bank (and the bridge to be rebuilt) . The curved portion was subsequently raised two feet with concrete, and the straight portion was temporarily raised twelve inches with wooden flashboards affixed to the top of the dam. Presently, some of the concrete on the downstream side of the curved dam is eroded, the "steps" have deteriorated and there is a leak through the old forebay; but the basic structure appears to be sound. The biggest threat comes from fluctuating water levels caused by intermittent and unpredictable releases from Stockton Lake." – National Register Nomination
The best view of the dam is from the bridge.
