Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is comprised of a 1,300 foot long, 49.5 foot high earth fill embankment having a concrete core wall. The reservoir is a pump storage facility, having no inlet stream or spillway. Between the design high water level, elevation 144, and the top of dam, elevation 147.5, there is 221 acre-feet of available storage. This capacity is sufficient to store all the runoff, 203 acre-feet, from the drainage area. There will be no test flood outflow. The dam will not be overtopped. The following remedial measures should be instituted by the Owner: grass and brush on the dam should be cut and maintained; animal burrows should be filled-in and prevented from reoccuring; trespassing on the dam should be prevented; a formal warning system for the downstream impact area should be developed and the dam should be inspected once every year by a qualified registered professional engineer.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lancaster Millpond Dam is a stone-masonry structure with stone abutments. It is 490 feet long and has an estimated hydraulic height of 24.5 feet. The spillway is 190 feet long and discharges to the Nashua River. As a result of the visual inspection and a review of available data, Lancaster Millpond Dam is considered to be in fair condition. Major concerns are: erosion of the soil near the right abutment on the downstream side; trees growing on the soil of the right abutment and on the field nearby; a tree growing out of the stone masonry at the intersection of the dam and the left training wall; seepage through the spillway; and the lack of controls on diversion and discharge structures. The test flood inflow was estimated to be 14,800 cubic feet per second (cfs) and resulted in an outflow discharge estimated to be 14,800 cfs, which would overtop the dam crest by about 13 feet. This would result in the water rising to within about 1 foot of the bridge at State Routes 62 and 70 immediately upstream of the dam.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mill Pond Dam is an earth embankment dam believed to have been constructed around 1900. The facility is used as a bridge across the Agawam River and to impound water for recreational purposes. The dam is about 285 ft. long and 16.5 ft. high. The dam has two spillways. The primary spillway is a concrete sluiceway located near the left abutment. A two bay stoplog structure located at the downstream end of the sluiceway controls flows through the facility. The secondary spillway is a 5 ft. dia. metal pipe culvert located on the right side of the dam. A stoplog structure having a weir length of 5.4 ft. is located on the upstream end of this spillway. An 18 in. dia. outlet passes through the dam near mid-point. Outflow is controlled at a 6 ft. by 8 ft. by 6 ft. upstream concrete intake structure. The dam and appurtenant works are judged to be in fair condition. There is no low level outlet for draining the pond. Seepage was noted at four locations. There was erosion of both the upstream and downstream embankments in the vicinity of the 18 in. dia. outlet pipe. Tree and brush growth is abundant. The test flood inflow is 3,420 cfs; the routed test flood outflow of 3,150 cfs would overtop the low point in the left abutment by about 2.0 ft. The spillways can pass about 7 percent of the routed test flood outflow without overtopping the low point in the left abutment.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1980 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is of irregular composition consisting of stone and earth embankments, two sluiceways, a spillway and several stone masonry wall sections. The dam has a hydraulic height of 11 feet and an overall length of approximately 120 feet. The spillway and sluiceways have a combined capacity of 230 cfs or 22 percent of the test flood outflow with flashboards and 345 cfs of 33 percent of the test flood outflow without flashboards. The dam is in generally good condition. However, it is rated as fair due to the inadequate spillway capacity, seepage through the stone masonry below the right sluiceway outlet pipe, and the voids beneath the cracked concrete floor of the spillway. It is recommended that the owner engage a qualified registered professional engineer to perform a detailed hydraulic/hydrologic investigation to determine overtopping potential and need for the total discharge capacity of the dam; design a means to precent water from seeping through the masonry below the right sluiceway outlet pipe and investigate the voids beneath the spillway cap.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1981 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simonds Pond is approximately 365 feet long and has a hydraulic height of 26 feet. The storage capacity is 86.5 acre-feet. The dam has a concrete cap and stone abutments. The emergency spillway is 48 feet long and occupies the center portion of the dam. As a result of the visual inspection and a review of available data, Simonds Pond Dam is considered to be in poor condition. Major concerns are: significant seepage at the toe of the dam; missing mortar and poor condition of the joints of the spillway; extensive spalling and cracking of the concrete cap on the top of the dam and spillway; deterioration of the spillway apron; extensive spalling of the concrete gatehouse foundation; and inadequate spillway capacity. The test flood inflow was estimated to be 2,500 cfs and resulted in an outflow discharge estimated to be 2,460 cfs, which would overtop the dam by approximately 1.3 feet. The maximum spillway capacity with the water level at the dam crest was estimated to be 700 cfs, which is approximately 28 percent of the test flood discharge.

Phase I Inspection Report written by CORPS OF ENGINEERS WALTHAM MA NEW ENGLAND DIV. and published by . This book was released on 1979 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chaffin Pond Dam is actually a section of roadway embankment approximately 135 ft. long, 11 ft. high and with a minimum width of 100 ft. Three submerged culvert outlets pass through the dam between upstream and downstream headwalls, allowing the water level to be the same on both sides of the dam. The control entrance to the assumed 30-in. diameter outlet on the left side has slots for stoplogs; however, none are in place. The control for a 4-ft. box culvert in the center is an open wood gate. The third outlet culvert is also gated but apparently blocked. Water from Chaffin Pond flows to outlet works at a second pond downstream from the dam where water is drawn for hydraulic research purposes. The dam is in poor condition, based on a visual examination of the structure. The headwalls have experienced major structural failures and the potential for a collapse of the upstream headwall with possible obstruction of flow to the outlet does exist. Hydraulic analyses indicate that the test flood would surcharge the pond by 680 acre-ft. and raise the pond level to about 4.2 ft. below the top of the dam. Therefore, no overtopping would be expected.
