The dam is located about 7 miles downstream of the Opekiska Lock and Dam and about 108 miles upstream of the Allegheny and Monongahela Rivers in Pittsburgh, PA. The purpose of the dam is to create a navigation pool from the dam to Opekiska Lock and Dam. The dam consists of a two concrete spillway sections and six steel gates through which the river flows. The lock provides a lift of about 21 feet, which is the height of the pool downstream of the dam (lower pool) to the pool upstream of the dam (upper pool). The lock allows river traffic to travel upstream or downstream of the dam. The lock consists of a rectangular chamber that is 84 feet wide by 600 feet long and formed on each side by concrete walls and steel gates on the upstream and downstream sides. The pool created by the dam also provides recreation opportunities for surrounding communities. The economic benefits of the dam are about 200 thousand dollars annually. The dam does not provide the nearby communities any protection from flooding.", "riskCharSummary":"The most recent risk assessment of the dam was performed in 2021, which characterized the risk as very low, because there is no potential for life loss or significant economic damages in the unlikely event that the dam fails. If the upper pool of the dam is released due to a dam failure, the consequences would be the loss of river traffic and recreation which would damage the regional economy by about 200 thousand dollars per year. The economic damage would be temporary, until the upper pool could be restored. Although this scenario is possible, the dam has performed well for over 80 years without incident. Due to the relatively short height of the dam, which lies entirely within the banks of the Allegheny River, downstream flooding would not be expected if the dam were to fail, and the upper pool was lost.", "riskManagementMeasures":"To ensure we are taking all steps to reduce the risk to the economy, we will continue to work closely with the Coast Guard, the Waterways Association, and the shipping industry to keep them aware of conditions at the dam and changes to lock operations. We conduct emergency exercises with our external partners to improve communication and reactions in the event of an emergency that threatens the dam or that may adversely affect economic benefits. We regularly update our emergency action plan. We conduct routine monitoring and surveillance of the lock and dam. We closely follow rainfall forecasts to determine when high river events may occur to provide information for any necessary public or industry notifications. We closely monitor river levels and provide advisories if river levels may become unsafe for shipping. Information on river levels and forecasts are available to the public via the internet at: \n\nhttp://water.weather.gov/ahps2/forecasts.php?wfo=pbz", "riverName":"MONONGAHELA RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":460, "stateFedId":"WV06107", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":64, "submitDate":"2023-02-16T17:25:30.694Z", "surfaceArea":405, "volume":0, "widthOfLocks":84, "secondaryWidthOfLocks":null, "yearCompleted":1960, "congDist":"Congressional District 02, West Virginia", "city":"MORGANTOWN", "county":"Monongalia", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":"2", "damTypeIds":"9", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1", "nonFederalDamOnFederalId":0, "designerNames":"CELRP", "otherNames":"Hildebrand Pool", "ownerNames":"USACE - Pittsburgh District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":3, "purposeIds":"3", "dsacId":5, "femaRegion":"3", "lastEapExcerDate":"2021-05-05T12:00:00.000Z", "dataUpdated":"2025-06-02T12:00:00.000Z", "usaceDistrict":"Pittsburgh District", "noConsequencesId":1, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":2, "damStatusId":2, "huc06":"050200", "doi_region":null, "doi_region_name":"North Atlantic-Appalachian", "doi_region_number":1 }, "id":16832111, "links":[ { "type":"application/json", "rel":"root", "title":"The landing page of this server as JSON", "href":"https://api.wwdh.internetofwater.app?f=json" }, { "type":"text/html", "rel":"root", "title":"The landing page of this server as HTML", "href":"https://api.wwdh.internetofwater.app?f=html" }, { "rel":"self", "type":"application/geo+json", "title":"This document as JSON", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/16832111?f=json" }, { "rel":"alternate", "type":"application/ld+json", "title":"This document as RDF (JSON-LD)", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/16832111?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/16832111?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
