"permittingAuthorityId":0, "politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers (USACE) built the J. Edward Roush Dam in 1967 across the Wabash River near the City of Huntington, Indiana as the eastern most of 3 dams to reduce the risk of flooding downstream on the northern portion of the Wabash River. USACE Chicago District operates and maintains the dam. The reservoir stores snow melt and rainfall runoff from late winter through early summer. Periodic releases of water from the reservoir occur throughout the year to maintain seasonally specified pool levels. Additionally, the reservoir provides recreational opportunities both in the lake and downstream. The dam structure is primarily an earthen embankment with a concrete center portion that contains 6 sluice gates and 3 tainter gates. The dam is approximately 6,500 feet long and 90 feet at the tallest point. Upstream of the dam are two embankments, Markle and Star of Hope, that protect areas that would have otherwise flood by the reservoir created by the dam. Normal discharges are through outlet works consisting of the 6 sluice gates in the center of the dam. Before the reservoir exceeds capacity, the 3 large tainter gates will be opened to control water levels within the reservoir. In the dam's more than 50-year history, these large gates have not been opened during a flood event. The pool of record at the dam occurred in July 2003 and nearly reached that same level in July 2015. The dam performed well during each of these high water events without any problems. To date, the dam has reduced downstream flood damages by more than an estimated $425 million.", "riskCharSummary":"The J.E. Roush Dam reduces the risk of flooding to downstream communities, however, the dam does not eliminate this potential flood risk. Downstream of the dam are the Cities of Huntington, Andrews, Lagro, Wabash, Peru, Logansport, Delphi, Lafayette, and Terre Haute, Indiana along with numerous other small towns and communities along the Wabash River all the way to the Ohio River. The most likely scenario for downstream flooding from the J.E. Roush Dam would be a high-volume release of water from the dam's gated spillway during major high water events. When the water level in the reservoir gets above a set elevation, the spillway gates will be opened releasing water to the Wabash River downstream to relieve pressure on the dam and to avoid the potential of water flowing over the top of the dam. The amount of water released could be great enough to cause flooding downstream. Higher releases from the spillway could create conditions similar to how the river would behave if the dam did not exist as the amount of water released would be controlled to match the amount of water coming into the reservoir. These releases could impact travel on State Route 5 (Warren Road), North Etna Road, State Route 9 (North Marion Road), and US 24 (Wabash Road) downstream of the dam. In addition, as the reservoir level increases, flooding will also be occurring upstream of the dam as the pool enlarges and extends nearly to the City of Bluffton, Indiana, about 16 miles to the southeast of the dam and could impact some local roads.\n\nThere are also two unlikely, but more devastating scenarios, that could result in significant flooding: 1) erosion of the soil foundation under the dam during a period of high reservoir levels that could lead to a breach; or 2) an extreme rainfall event that could result in water flowing over the top of the earthen embankment of the dam, eroding the dam and leading to a breach. In either scenario, an uncontrolled surge of water would flow out of the reservoir, flooding downstream communities. The communities of Huntington and Andrews and other residences and businesses located in the valley below the dam would be in immediate danger if this were to occur. Cities further downstream, including Wabash, Peru, Logansport, and Lafayette would also see large damaging flood conditions, but would have more warning time to respond. In the two scenarios described above, the downstream floodwater would be swift and deep, overtopping levees, destroying buildings and key infrastructure, and those caught unaware and unable to evacuate could perish.", "riskManagementMeasures":"USACE is taking several steps to reduce the risk to the public. USACE staff are continuously on-site to operate and maintain the dam. USACE works closely with state and local emergency managers, regularly conducts emergency exercises, and routinely updates the emergency action plan (EAP) for the dam. USACE also conducts rigorous inspection, monitoring, and surveillance of the dam, especially during high water events. USACE also closely follows rainfall forecasts to determine when high water events may occur and provide information for any necessary flood warnings. USACE continues to work with local communities to help them understand how they can better prepare for a flood.", "riverName":"WABASH RIVER", "separateStructuresCount":2, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":135, "stateFedId":"IN03006", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":91, "submitDate":"2023-10-31T00:00:00.000Z", "surfaceArea":900, "volume":1111000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1968, "congDist":"Congressional District 03, Indiana", "city":"HUNTINGTON", "county":"Huntington", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":null, "damTypeIds":"11;8;9", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":"Huntington Lake Dam", "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"CELRL", "otherNames":"J.
