The 48 hour regional forecast is calling for areas of rain from 2” to 4” in the Ocheyedan and Little Sioux River Basins. These amounts will increase the potential for localized street flooding as collection systems work to drain the rainfall away from impacted neighborhoods as well increase river levels during and after the rainfall events. Clay County is in a flash flood watch for the next 36 hours. Periods of heavy localized rain may cause flash flooding conditions in neighborhoods. River levels in the Ocheyedan and Little Sioux Rivers that flow through Spencer at the Grand Avenue Bridge are forecasted to potentially reach 10’ resulting in a Minor Flood Level 1 rating (see attached graphic). The current river level at the Grand Avenue Bridge as of 2:15pm, June 25, 2025 is 5.6’. Moderate Level 2 flooding begins at 14’ and Major Flood Level 3 at 16’. The disaster of 2024 was a river level of 22’. Staff will continue to monitor the forecast and is in constant communication with the Iowa Flood Center and the National Weather Service regarding weather risk during this weather event. The City of Spencer encourages all citizens to remain weather aware.
