White River Basin Dams

LITTLE ROCK, Ark. (USACE) - The Little Rock District of the U.S. Army Corps of Engineers reports that its six lakes in the White River basin are earning theirs keep reducing flood damages downstream along the White and Black rivers.

People who live or work in flood plains below these dams should maintain awareness by monitoring weather and news media.  Beaver and Table Rock lakes both reached their flood storage capacities and are currently falling. 

Norfork and Clearwater lakes are expected to approach their flood storage capacities over the weekend. 

When this occurs, and if more heavy rain is forecast, people should decide beforehand whether to move belongings to higher ground.  Flows downstream can increase quickly, with perhaps no more than an hour or two notice, and rapidly changing conditions could create even shorter notice.

People in at-risk areas should stay in contact with local emergency officials.  If larger than normal releases are required from a dam, warnings will go out through local emergency channels.  Local officials may not know you require notification unless you have told them so.

 

Conditions at the six White River Basin lakes as of Friday morning were as follows.

Table Rock Lake near Branson, Mo.:  The lake elevation Friday morning was 934 feet and falling, with 121 percent of the flood storage capacity in use.

April rainfall through Friday morning was 13.6 inches, with 10.5 inches falling this past week.  Releases from the spillway and powerhouse total of 68,000 cubic feet per second and remain that level until the lake reaches 931 feet. 

Beaver Lake near Rogers, Ark.:  The lake was at elevation 1,129.1 feet Friday morning and falling.  About 90 percent of the lake's flood storage capacity is in use.  The lake can handle about one-half inch more runoff.  April rainfall through Friday morning was 15.1 inches, with 11.5 inches falling this past week.  Releases from the spillway and powerhouse will be reduced to 4,500 cubic feet per second Friday afternoon.

Norfork Lake near Mountain Home, Ark.:  The hydropower units are being repaired at the power house, so the Corps is making releases from the dam's spillway gates instead.  The releases are comparable to what would go through the powerhouse if the units were operational.  The lake was at elevation

578.7 Friday morning and rising, with 95 percent of flood storage capacity in use.  The gates are set to release 2,100 c.f.s., which is about equal to average minimum flood control releases (simulates firm power).  Total April rainfall through Friday morning was 16.8 inches, with 13.2 inches falling this past week.  

Bull Shoals Lake near Mountain Home, Ark.:  The lake elevation Friday morning was 680.4 feet and rising, with about 59 percent of the lake's flood storage capacity in use.  The lake can handle about 3 inches more runoff.  Releases at the dam are restricted to 3,750 c.f.s. which is equal to average minimum flood control releases (simulates firm power).  Total April rainfall through Friday morning was 15.3 inches, with 12.1 inches falling this past week.

Greers Ferry Lake near Heber Springs, Ark.:  The lake elevation Friday morning was 472.3 feet and rising, with 39 percent of the lake's flood storage capacity in use.  The lake can handle about 9.4 inches more runoff.

Total April rainfall through Friday morning was 10.6 inches.
