"permittingAuthorityId":0, "politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers completed the construction of Deer Creek Dam in 1968. The project was authorized by the Flood Control Act of 1938, Public Law 75-761. The authorized project purposes include flood control, water conservation, recreation, and fish and wildlife management. Water quality control was later added as an authorized project purpose by the Federal Water Pollution Act of 1948 as amended under section 2 of Public Law 87-88 in July 1961\n\nDeer Creek Dam is located on Deer Creek in Pickaway County, Ohio, about 21 miles upstream from Deer Creek\u2019s confluence with the Scioto River and 105.8 miles from the confluence with the Ohio River. The dam is 5.4 miles northwest of Williamsport, Ohio and 22 miles northwest of Chillicothe. New Holland Dike is located about 3.8 miles southwest of Deer Creek Dam. The village of New Holland is 1.38 miles downstream of the dike. The authorized project purposes include flood control, water conservation, recreation, and fish and wildlife management. This project has prevented over $102.8 million in flood damages between its completion in 1968 and 2013, resulting in average yearly flood damage prevention of $2,200,000.\n\nDeer Creek Dam is a low hazard potential dam at a length of 3,880 feet and a height of 95 feet. The low hazard potential means it is unlikely to result in loss of human life and significant economic loses if breached. It is comprised of a concrete gravity dam with an earthen embankment on either side and controls a drainage area of 277 square miles. Normal flow is passed through sluice gates in the dam, and the dam is outfitted with a Tainter gate controlled overflow spillway for flood control.", "riskCharSummary":"The dam significantly reduces the risk of flooding to surrounding communities. However, it does not entirely eliminate the risk. Although Deer Creek Dam has historically performed well, extreme rain events may cause areas downstream to be flooded. Even when the dam operates as intended, downstream flooding could still occur in a very large rainfall event. This event could require unusually large quantities of water to be released through the dam gates and emergency spillway. In extreme cases, this flooding could be similar to what was experienced prior to the dam's construction.\n\nA 2018 risk assessment for Deer Creek Dam and New Holland Dike classified both as having low risk of failure during a flood. Although risks associated with a breach or failure are low, the dam does not completely eliminate flood risks downstream. Flooding can still occur even if Deer Creek Dam is operating as designed. There are extremely rare (but possible) storms that could cause more rainfall than the dam can safely store. During such an event, the dam has the potential to pass up to 125,000 cubic feet of water per second. The amount of flow would be necessary to prevent the dam from overtopping and potentially breaching. \n\nThe Deer Creek Dam spillway has never been utilized, if operated it could result in\nsignificant flooding. Depending on the amount of water released, significant damages to houses, buildings, and critical infrastructure, including roadways (evacuation routes) and bridges along Deer Creek may not be passable due to high flood waters during spillway flows. Although the odds of such a storm event occurring are considered extremely unlikely, Deer Creek Dam has an emergency action plan to lower the risk of life loss if any unanticipated scenarios were to occur.\n\nWhile rare events like these have not occurred to date, if they were to happen, water is likely to reach high elevations quickly and be more than tens of feet deep depending on the location. In the rare event Deer Creek Dam must pass these extreme flows, follow all directions from emergency officials, including evacuation orders. Failure to do so puts you and your family\u2019s lives at risk.", "riskManagementMeasures":"There are numerous activities that U.S. Army Corps of Engineers conducts on a day-to-day basis to help manage risk at Deer Creek Dam and New Holland Dike. The project is well maintained through continuous operations and maintenance activities, and U.S. Army Corps of Engineers conducts detailed inspections of the dam and dike during both normal lake levels and during flood events. Supplementing these inspections, the dam has specialized instrumentation and a monitoring system to allow U.S. Army Corps of Engineers staff to continually evaluate the dam for changing conditions. Risk management and emergency response actions are being supported by conducting emergency exercises and dam safety training with U.S. Army Corps of Engineers staff and local and state emergency responders. Additionally, the dam and dike Emergency Action Plan is routinely updated to improve emergency response actions.", "riverName":"DEER CREEK", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":126, "stateFedId":"OH00008", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":93, "submitDate":"2023-12-01T19:03:45.745Z", "surfaceArea":1277, "volume":1681091, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1968, "congDist":"Congressional District 02, Ohio", "city":"WILLIAMSPORT", "county":"Pickaway", "aiannh":null, "websiteUrl":"https://www.lrh.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"3", "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CELRH", "otherNames":"Deer Creek Lake", "ownerNames":"USACE - Huntington District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;4;5", "dsacId":4, "femaRegion":"5", "lastEapExcerDate":"2024-07-16T12:00:00.000Z", "dataUpdated":"2025-04-21T12:00:00.000Z", "usaceDistrict":"Huntington District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"050600", "doi_region":null, "doi_region_name":"Great Lakes", "doi_region_number":3 }, "id":868108, "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/868108?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/868108?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/868108?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
