Overview

Several rounds of heavy rain and thunderstorms occurred across the region over the past week, which lead to increasing river levels along local rivers. Along the Mississippi, a new, preliminary historic crest of 22.7 feet was achieved on the afternoon of May 2, 2019 at Rock Island Lock & Dam 15, as runoff from the heavy rain and flow from tributaries worked into the river.

A failure of a flood protection barrier occurred in Davenport, IA near River Drive and Pershing Ave on April 30th. This failure caused rapid rises that affected many businesses. A summary of this breach can be found here.
