The map is included in the city's latest Multi-Hazard Mitigation Plan which was published over the summer.

The map shows much of Brookside and areas south of there, on the east bank of the Arkansas, under water.

That's low-lying land that would flood from Lake Keystone; if the dam failed, if the levees failed or if there was so much rain it led to that much water going through the dam.

"So people need to know about the dams and levees, about the places in flood zones and the things people can do if they have property that's suffered a repetitive loss or flood event," said Tim Lovell with Tulsa Partners.

The flood map is on page 259 of the plan.
