Bickford Pond Dam which was built in 1970 is a 933-foot long earth dam with concrete core wall. The dam has a maximum height of 51.2 feet and includes a drop inlet spillway and box conduit outlet structure. Bickford Reservoir Dam, also known as the Bickford Dike, was built in 1970 and is a 507-foot long earth dam with a concrete core wall. The dam has a maximum height of 18.3 feet. There are no spillways or outlet structures at this dam. The following deficiencies were observed at Bickford Pond Dam seepage through cracks and joints in the box conduit outlet structure unmonitored seepage through core wall toe drains and downstream slope toe drains siltation and partial blockage of discharge ditches from toe drains riprap dislodged from the upstream face of the dam cracked, spalled and eroded concrete in the box conduit and spillway growth of brush and saplings through riprap on upstream face of dam and tire ruts along the top of the dam. The following deficiencies were observed at the Bickford Reservoir Dam unmonitored seepage through downstream slope toe drains growth of brush and saplings through riprap on upstream face of dam and growth of brush and saplings on downstream face of dam and growth of brush and saplings on downstream face of dam. The test flood would overtop the Bickford Pond Dam by 0.2 foot and Bickford Reservoir Dam by 0.1 foot. Hydraulic analyses indicate that the spillway can discharge 5,100 cfs, or 93 percent of the test flood outflow before the dam is overtopped.
