National Program for Inspection of Non-Federal Dams. Baldwins Pond Dam (CT 00133), Connecticut Coastal Meriden, Connecticut. Phase I Inspection Report
Baldwins Pond Dam is an earthen embankment dam with a downstream vertical stone masonry wall extending along about two thirds of the dam length. The total length of the dam is 190 feet including the spillways, while the maximum height as measured from the left spillway abutment is 15.5 feet. The width of the dam varies from a minimum of 9 feet at the left spillway abutment to 17 feet near the middle of the right embankment. The maximum impoundment with water at the top of dam is 40 acre-feet. The main spillway is a 62 foot long vertical stone masonry wall located on the left side of the dam while there is an emergency spillway consisting of 19 foot long, 8 inch wide concrete wall near the right abutment. There are three outlets associated with the dam. The visual inspection of Baldwins Pond Dam indicated that the dam is in poor condition. The inspection revealed that there was extensive seepage at the emergence spillway and significant seepage through and displacement of the downstream stone masonry wall. In addition, there were trees growing on the right dam embankment which could create further seepage problems, especially if they become uprooted during storms. There was an area of overtopping of the reservoir bank upstream of the left dam abutment. There was inadequate riprap or concrete protection of the soil on the upstream dam face and on the dam crest at the emergency spillway and along the emergency spillway discharge channel. The peak outflow is 4035 cfs which will result in overtopping the dam by 2.4 feet. The combined capacity of the spillways is 490 cfs or 12% of the peak outflow.
