Homme Dam and Reservoir Dam Safety, North Dakota
Location/Description
|
Homme Dam is located in northeastern North Dakota on the South Branch of the Park River, upstream of the cities of Park River, N.D., and Grafton, N.D. The project was first placed in operation on Dec. 1, 1950, and is operated and maintained by the federal government, except for a water supply line, which is maintained by the city of Park River. The original project construction was cosponsored by the cities of Park River and Grafton.
|
Status
|
Construction to complete replacement of the existing fixed crest spillway was completed in 2004. Soon thereafter, problems were discovered with the erosion of an embankment adjacent to the spillway abutment and with unanticipated seepage through the sub-drain system. The erosion problem has been corrected with a minor maintenance effort. The sub-drain seepage problem is under investigation to determine a cause and recommend a remedy.
|
Additional
|
In 1994, the Assistant Secretary of the Army (Civil Works) approved a dam safety reconnaissance report recommending adding a new spillway to increase the dam’s discharge capacity from 44 percent of the Probable Maximum Flood to 100 percent of the PMF. Subsequent investigations determined that the existing spillway was not reliable. Both high uplift pressures and material voids under the spillway indicated a seepage path through the dam. Relocating the spillway was the more cost effective solution. Construction of a new spillway and removal of the existing structure was completed in 2004.
|
Authority
|
Congress authorized the Park River project in the Flood Control Act of Dec. 22, 1944. The Chief of Engineers approved the definite project report on Aug. 28, 1947. Public Law 435 redesignated the Park River project as Homme Dam on March 5, 1948.
|
Fiscal
|
The project is cost shared between the federal government and the non-federal sponsors, the cities of Grafton and Park River. Operation and maintenance costs are 100 percent federal. In fiscal year 2008, $230,000 was appropriated to repair erosion and investigate seepage.
Estimated federal cost $12,235,000
Estimated non-federal cost $81,000
Total $12,316,000
