Abstract:

Based on the visual inspection and the results of the hydrologichydraulic investigations, the present general condition of the dam is considered to be somewhat less than satisfactory. Deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam. Evidence of seepage, soft and wet ground near the toe of the center of the dam soft ground and flowing water at the intersection of the toe of the dam and the right abutment and running and standing water and cattails downstream of the toe of the dam was observed. The right bank of the outlet channel for the emergency spillway at a point adjacent to the dam was eroded to an extent that spillway releases within the capacity of the outlet would not be confined to the channel. Damage by unconfined spillway releases to the dam and to other areas downstream of the dam can occur during periods when lake outflow passes the emergency spillway. Erosion of the grass covered upstream face of the dam apparently by wave action andor by fluctuations of the lake surface level has created a near vertical bank approximately 6-to-12 inches high at the normal waterline.
