National Dam Safety Program. Blackwood Lake Dam (NJ00800). Delaware River Basin, South Branch Timber Creek, Camden County, New Jersey. Phase 1 Inspection Report.
Abstract
Blackwood Lake Dam is on the boundary of Gloucester Township in Camden county and Washington Township in Gloucester County. The visual inspection was conducted on September 3, 1980, at which time the water level in the lake was producing a moderate flow over the three-celled sluiceway (which prevented close inspection of the timber stop logs). The overall physical condition of the dam is fair, but the embankment slopes are very poorly graded, especially at the bridge downstream wingwalls. The roadway embankment, which forms the main dam structure, was assessed to be in a solid and stable condition, although pavement runoff at the gutter lines causes a continual drainage problem, especially on the downstream side. The crest of the dam is an asphalt-paved two-lane road. A considerable portion of the downstream sideslopes adjacent to the wingwalls has been heavily eroded, particularly on the left. This may be due to a combination of poorly compacted fill that was replaced after the flood of 1967 and the erosion from roadway runoff.
