National Dam Inspection Program. Cloe Dam (NDI ID Number PA-421, DER ID Number 33-2), Ohio River Basin, Jackson Run, Jefferson County, Pennsylvania. Phase I Inspection Report.
Abstract
Cloe Dam consists of an earth embankment approximately 900 feet long with a maximum height of 43 feet from the downstream toe and a crest width of 14 feet. The upstream face of the dam is protected by hand-placed riprap. The crest and the downstream slope extending from crest level to a berm at midheight of the embankment is covered with grass. The downstream slope below the berm level is protected by riprap. The flood discharge facilities for the dam consist of an 85-foot-wide rectangular concrete overflow structure located on the left abutment (looking downstream). A concrete wall parallel to the flow direction divides the overflow structure into two open channels. The 50-foot-wide channel adjacent to the left abutment consitutes the primary spillway of the reservoir. The remaining 35-foot section of the overflow structure adjacent to the embankment provides auxiliary spillway capacity. The crest of the auxiliary spillway section is 0.4 foot above the crest level of the primary spillway, as measured during this inspection. The outlet works consist of a reinforced concrete intake tower, two 10-inch cast-iron supply pipes, and two 24-inch cast-iron outlet pipes. Pipes through the embankment are encased in concrete. Flow through the outlet pipes is controlled by manually operated sluice gates located in the intake tower. The two 24-inch outlet pipes constitute the emergency drawdown facility for the reservoir.
