It is a high hazard potential dam located on Mill Creek, 2.9 miles above its junction with the Eel River. The project is located approximately 40 air miles southwest of Indianapolis and 25 miles east of Terre Haute in Putnam County, Indiana. The project consists of a 900-foot-long embankment with a maximum height of 150 feet, a gate-controlled outlet tunnel through the base of the right abutment, and a 285-foot-wide uncontrolled, open cut spillway on the left abutment. The project reduces flood damages along approximately 2.9 miles of Mill Creek and along the Eel and White River up to its confluence with the Wabash River. The project has a drainage area of approximately 295 square miles. The record pool elevation of 691.71 ft-NAVD88 occurred on 18 June 2008 and did not result in spillway flow (El. 703.6 ft-NAVD88).", "riskCharSummary":"USACE completed a risk assessment for Cagles Mill Dam in July 2022 that characterizes the risk of the project as a Dam Safety Action Classification (DSAC) 5 which is considered Very Low relative to the dams USACE owns and operates. The dam significantly reduces the risk of flooding to downstream communities. However, it does not eliminate the risk completely. Even when the dam operates as intended, downstream flooding could still occur if a very large rainfall event were to result in unusually large quantities of water to flow through the dam spillway. There is also a very unlikely, but far more disastrous scenario that would produce significant flooding, which is erosion of the dam\u2019s embankment during a period of high reservoir levels that could lead to a breach of the dam. In this unlikely event, an uncontrolled surge of water could flow out of the reservoir, resulting in potentially deadly flooding along Mill Creek and Eel River.\n\nIf a dam failure occurred, water from the reservoir would flood downstream areas. The surrounding areas are rural agricultural in nature with sparse scattered development generally along the fringe of the floodplain. Residential structures along the banks of Mill Creek and Eel Creek would be majorly impacted. Worthington, IN located approximately 60 miles downstream of the dam, could be impacted by large flood events.", "riskManagementMeasures":"USACE is continuously taking significant steps to reduce the risk to the public. This includes working closely with local emergency managers, regularly updating the Emergency Action Plan, and conducting emergency exercises with state and local response teams. USACE utilizes the latest forecast and stream gauge information and coordinates closely with the National Weather Service concerning conditions both upstream and downstream of the dam including inflow, outflow, and precipitation. Rainfall forecasts are used to determine when high pool events may occur. USACE regularly inspects and monitors instruments to assess the health of the dam. The frequency of these checks increases when the lake level rises. This ensures that the structure is performing as designed and could help detect any areas of potential concern. Regular maintenance and repairs are performed as needed to keep the dam functioning properly.", "riverName":"MILL CREEK", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":285, "stateFedId":"IN03002", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":150, "submitDate":"2023-11-29T21:50:30.795Z", "surfaceArea":1400, "volume":2170000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1953, "congDist":"Congressional District 04, Indiana", "city":"BOWLING GREEN", "county":"Putnam", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":null, "damTypeIds":"5;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"CELRL", "otherNames":"Cagles Mill Lake", "ownerNames":"USACE - Louisville District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5", "dsacId":5, "femaRegion":"5", "lastEapExcerDate":"2024-01-18T12:00:00.000Z", "dataUpdated":"2025-03-17T12:00:00.000Z", "usaceDistrict":"Louisville District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"051202", "doi_region":null, "doi_region_name":"Great Lakes", "doi_region_number":3, "thirtyYearAverage":61.3101, "tenthPercentile":33.6832, "ninetiethPercentile":100.7316 }, "id":1091109, "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/1091109?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/1091109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1091109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
