Abstract:

Hartford Reservoir No. 3 Dam is a 105-year old earth embankment approximately 500 feet long with a maximum height of about 41 feet. The dam impounds water for use at the power generation facilities located 100 feet downstream of Hartford Reservoir No. 1 and for diversion to Hartford Reservoir No. 5 for eventual treatment and distribution in the City of Hartford water supply stream. Normally, surplus water from Reservoir No. 3 discharges through the spillway and flows downstream to Reservoir No. 1. During periods of high demand, water may be diverted to Reservoir No. 5 by means of a 20-inch diameter pipe and an open channel at the northern end of the reservoir. The spillway is capable of discharging one-half of the PMF with approximately 1.7 feet of freeboard. On the date of inspection, Hartford Reservoir No. 3 Dam generally appeared to be in fair condition. However, several deficiencies were observed during the inspection. A wet spot, apparently resulting from seepage through the embankment, extends along the downstream toe of the dam for a 50-foot distance. In addition, a section of the slope has failed above the wet area, leaving a one-foot high scrap approximately six feet above the downstream toe. Due to this condition, the dam is considered to be in poor condition. Animal burrow holes were also observed in the downstream face of the dam. Riprap has been displaced from the upstream slope and several trees are growing from the upstream face of the embankment.
