National Dam Inspection Program. Pistapaug Pond Dam (CT 00034). Connecticut Coastal, Wallingford, Connecticut. Phase I Inspection Report
Pistapaug Pond Dam is an earthen embankment dam with a concrete core wall. The dam is 9.2 feet high, 17 feet wide at the crest and approximately 370 feet long. There is a spillway with flashboards located near the middle of the dam. A gatehouse located on an embankment 100 feet downstream of the dam controls discharges into the Wallingford Water Supply System. A 16-inch force main and open channel system coming from Ulbrich Reservoir supplies water to Pistapaug Pond. The reservoir is used for water supply purposes and has a maximum storage capacity of 4540 acre-feet with water at the top of dam. The visual inspection of Pistapaug Pond Dam indicated that the dam is in fair condition. The inspection revealed that the dam had some minor erosion at the downstream toe adjacent to the left spillway training wall as illustrated in Photo No. 15. The spillway weir and training walls were spalling and efflorescing in a number of places as shown in Photo No. 13. In addition, the downstream spillway apron was clogged with weeds and brush and lacks riprap protection. Also there is lack of an adequate spillway channel. The upstream slope of the dam exhibited irregular riprap protection.
