reconstructed it as a more permanent concrete structure during April 1905 \u2013 June 1906. Pine River Dam is one of six headwaters\u2019 dams on the Mississippi River. The headwaters dams were constructed to supplement river flows for navigation purposes by filling the lakes in the spring and drafting them down as needed during the summer; but the headwaters dams have rarely been used for that purpose since the water control plans were revised in 1945. The downstream lock & dam system constructed in the 1930\u2019s nearly eliminated the need for upstream water storage, so the dam is primarily operated to optimize recreation and environmental benefits. The dam has a concrete control structure and 16 reservoir rim dikes. The dam is founded on timber bearing piles, although the new wingwalls added in 2001 have steel bearing piles. There are 13 spillway bays each equipped with dual-leaf slide gates.", "riskCharSummary":"USACE considers Pine River to be a low-risk dam (DSAC-4) among its more than 700 dams. The risk ranking is based on a screening-level assessment in 2009 that cited primary concerns as seepage at two dikes. Although the dam was modified in 2001 for extreme floods (70% of the probable maximum flood), the water levels are held very stable by the storage capacity in the reservoir, the control structure discharge capacity, and winter drawdown planning for spring floods. Breach modeling does show a hazard including direct loss of life for both the dam and some of the dikes, so the dam is listed as a high hazard dam.\nDams do not eliminate all risk of flooding. USACE works to address all types of flood risk associated with the dam. Dams have limited capacity to store water. Historic outflows from the dam have been less than 2500 cubic feet per second (CFS), but the dam has capacity to discharge up to 16,300 cfs. Water released through the dam to relieve pressure on the dam to maintain its structural integrity could cause downstream flooding, although this would be extremely rare. The upstream reservoir has capacity to store water for flood risk management and the USACE operations use winter drawdowns to minimize high outflows from snowmelt in the spring.", "riskManagementMeasures":"USACE manages dam-related flood risks by continually monitoring the condition and health of the dam, prioritizing activities that will most impact the risks, and engaging upstream and downstream emergency managers and members of the public to raise awareness of the dam and support actions to prepare and be ready to respond in the case of a dam-related emergency. USACE works closely with local emergency managers to share what is known about the dam and support the development of local emergency and evacuation plans. USACE regularly updates the emergency action plan for the dam. A dam safety assurance modification was completed at Pine River Dam and two of the reservoir rim dikes in 2001, and regular maintenance and repairs are performed as needed to keep the dam functioning properly.", "riverName":"PINE RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":0, "stateFedId":"MN00582", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":22, "submitDate":"2023-02-16T17:25:12.699Z", "surfaceArea":13700, "volume":112300, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1886, "congDist":"Congressional District 08, Minnesota", "city":"CROSS LAKE", "county":"Crow Wing", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":"3", "damTypeIds":"11;2;8;9", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":"Crosslake Dam", "foundationTypeIds":"3", "nonFederalDamOnFederalId":0, "designerNames":"CEMVP", "otherNames":"Pine River Reservoir", "ownerNames":"USACE - St. Paul District", "ownerTypeIds":"3", "primaryDamTypeId":11, "primaryOwnerTypeId":3, "primaryPurposeId":5, "purposeIds":"5;12;3;4;8;9", "dsacId":4, "femaRegion":"5", "lastEapExcerDate":"2022-03-15T12:00:00.000Z", "dataUpdated":"2024-11-14T12:00:00.000Z", "usaceDistrict":"St. Paul District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"070101", "doi_region":null, "doi_region_name":"Great Lakes", "doi_region_number":3, "thirtyYearAverage":117.9495, "tenthPercentile":107.7466, "ninetiethPercentile":125.8798 }, "id":3871016, "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/3871016?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/3871016?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/3871016?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
