National Program for Inspection of Non-Federal Dams. Samp Mortar Reservoir Dam (CT 00017), Mill River Basin, Fairfield, Connecticut. Phase I Inspection Report
Samp Mortar Reservoir Dam is a 320 foot long concrete and earth embankment dam and has a maximum height of 29 feet. The major portion of the dam is an ogee-shaped overflow spillway section which is abutted by concrete and earth embankment sections which are connected to original ground. The top width of the ogee spillway section is 8 feet. The top width of the outer sections is 7.5 feet. The spillway is located on the center portion of the embankment and is 185 feet long. The visual inspection of Samp Mortar Reservoir Dam indicated that the dam is in fair condition. The inspection revealed some soil erosion on both abutments. Trees are growing from both abutments. Several seepage zones were observed on both abutments. Water from 24 and 30 inch pipes along the toe of the left abutment has eroded the left abutment. Also, there are numerous trees in the downstream spillway channel. Based on its small size and high hazard classification and in accordance with the Corps guidelines the test flood is equal to the Probable Maximum Flood. The spillway will discharge 5270 cfs or 32% of the test flood with the pool level at the top of the dam. The test flood flow of 16,500 cfs will overtop the dam by 3.9 feet.
