Two Mississippi River locks in the Twin Cities were closed to recreational vehicles Saturday because of high water flow, according to the Army Corps of Engineers’ St. Paul District.

The Lower St. Anthony Falls Lock and Dam, as well as Lock and Dam 1, located near Minnehaha Falls, were closed because the water speed exceeded regulated levels for recreational traffic.

Flows reached 30,000 cubic meters per second, the maximum allowed by the Corps Mississippi Valley Division for recreational traffic. Commercial traffic is permitted during flows of up to 40,000 cubic meters per second.

The Corps reminded boaters to be cautious of currents and high water, to wear life vests and to be wary of submerged logs and debris that can resurface and damage watercraft during swift-water conditions.
