TheTittabawassee River (/ˈtɪtəbəˈwɑːsi/TIH-tə-bə-WAH-see) flows in a generally southeasterly direction through theLower Peninsula of theU.S. state ofMichigan. The name Tittabawassee likely comes from Chippewa/Ojibwe "Ditib-Waasizo" meaning the Rolling & Sparkling River from its curved shape and shining or sparkling water. The river begins at Secord Lake inClement Township, at theconfluence of the East Branch and the Middle Branch.[3] From there it flows throughGladwin,Midland andSaginaw counties where, as a major tributary of theSaginaw River, it flows into it atSaginaw. Its tributaries include theChippewa,Pine,Molasses,Sugar, andTobacco rivers.
Significant communities on or near the Tittabawassee River include Saginaw,Midland, andSanford. At Edenville, the river was impounded by the hydroelectricEdenville Dam to createWixom Lake. It was also impounded by theSanford hydroelectric dam in Sanford to createSanford Lake prior to the dam failures and resulting flooding on May 19, 2020. In Saginaw County, the river flows throughTittabawassee Township, which is named for the river and contains the unincorporated community ofFreeland.
The main river is 72.4 miles (116.5 km) long[3] and drains an area of 2,471 square miles (6,400 km2).[4]
On May 19, 2020, the Edenville Dam failed, followed by the Sanford Dam downstream being overtopped and a dike breaking at Poseyville, resulting in major flooding in Midland County.[5][6][7] 10,000 people were evacuated including a seniors home and a few hospital patients.[8][9] Two emergency shelters had to be relocated due to flooding and electrical power losses. Floodwater entered theDow Chemical plant, forcing its shutdown and mixing with its containment ponds, leading to concern over pollution.[10] The next day, water levels were predicted to reach 38 feet: four feet higher than the flood of 1986.[11] National Guard units and aFEMA team were brought in to assist.
