High temperatures in the mid to upper 70s will increase runoff from the remaining snowpack in the higher elevations of the St. Joe Basin. This will keep the level at St. Maries near flood stage over the next few days. The Snake River at Shelley was just over flood stage yesterday at 12.3 feet. Required releases form the Palisades Reservoir will bring the Snake River at Shelley to near 13.0 feet on Wednesday, a foot above flood stage. These are the highest flows of the spring runoff so far and will cause significant flooding of low land areas.
Minor flooding continues at some locations along the Lower Ohio River.
The river flooding is a result of recent heavy rain upstream along and just to the north of the Ohio River Basin. The Wabash River continues to rise at New Harmony due to the runoff from the heavy rains this weekend. Lowland flooding will continue along portions of the Wabash River through June 20th. The combination of high water from the White River and another rise traveling down the Wabash continued to push the Wabash River at Mount Carmel Illinois steadily higher last night. Extensive flooding will continue along the White River in southwest Indiana through Friday.
