Episode Narrative Mountain snowmelt along with periods of moderate rainfall led to high flows on the Coeur d'Alene and St. Joe Rivers. Temperatures in the valleys across northern Idaho climbed into the seventies and lower eighties from April 23rd through the 26th. This warm spell was then followed by a cooler, but wet pattern through the end of April. The combination of snowmelt and rainfall resulted in main stem river flooding in the Coeur d'Alene and St. Joe River basins. High levels on Lake Coeur d'Alene resulted in a slow recession of the St. Joe River at St. Maries, which continued to have flooding problems into the month of May.
Event Narrative Flood waters from the St. Joe River at St. Maries covered Lagoon Road and inundated some residential properties in this area. Some damage was observed to the levees. There was a rotational failure on the riverward side and slippage in a part of the one of the levees. Damage reported was estimated.
