DEVILS LAKE, N.D. (AP) - As Devils Lake in north-central North Dakota continues to rise, concern is growing about how to prevent a spillover into the Sheyenne River and potentially devastating flooding downstream.

The lake has risen more than 30 feet during a wet cycle that began in 1992 and is within 6 feet of its natural overflow, at which point water would run through a coulee and across land into the Sheyenne River. The spillover would threaten downstream communities.

The lake rose 3 1/2 feet last year, and concerns about a spillover are growing.

City engineer Mike Grafsgaard says the coulee is susceptible to erosion and could give way, sending a torrent of water downstream. He suggests a dam should be built on the coulee's high ground to help regulate flows into the Sheyenne.
