spillway

Next to the lake, a spillway flows into a stream that the Department of Water Resources refers to as Blue Canyon Creek.

Some of what they remove will be used to fill in the dam’s emergency spillway which is carved into the rock beside the river.

Opening the spillway diverts Mississippi River water to Lake Pontchartrain and Lake Borgne, after which it flows to the Mississippi Sound in the Gulf of Mexico.

Lowry found fields of half-submerged corn, soybeans that had disappeared under the flooding almost entirely and rapids rushing from their spillway like a waterfall.

The first thing I saw after claiming a parking spot was a vivid rainbow hanging in the mist above the dam’s spillway.
