WOLF CREEK DAM FAILURE

I. HISTORY

Wolf Creek Dam/Lake Cumberland is located in the western part of Russell County, Kentucky,

approximately 150 miles northeast of Nashville, Tennessee. Construction was begun on the dam in 1938 and completed in 1950. Wolf Creek Dam is the largest dam east of the Mississippi River and is the ninth largest reservoir in the United States. The dam, located on the Cumberland River, has a shoreline of over 1,200 miles, and holds 6.1 million acre-feet of water (enough water to cover all of Kentucky with three inches of water).

The dam has been leaking since its construction, but recent changes along the dam have proven serious enough that the federal government to repair the dam has appropriated over 300 million dollars and dam engineers have seen fit to bring the leakage of the dam to public attention. Wolf Creek Dam is the worst rated dam in the US. The geology of the area resulted in the dam being built upon limestone (Karst’s Geology) that, after being mixed with water over time, has slowly eroded the rock and clay used to create the dam. Water is leaking through underneath the dam and forming sinkholes and wet spots on the riverside and also has resulted in over 4,000 feet of the 5,600-foot (lengthwise) sinking approximately three inches.

class=Section4>

Repeated attempts to get actual numbers related to the projected water levels of Wilson County

from the Corps of Engineers (COE) have proven unsuccessful. Flood level estimates have ranged from 465 feet MSL (altitude measured from Mean Sea Level) to 492 feet. The closest flooding estimates for Wilson County at the levels for winter & summer pool and flood stage are based upon estimates made by the COE for Hartsville, Tennessee. Their numbers were given as 475, 485 and 492 feet MSL, respectively. The emergency operations plan will use these flood values until the COE can produce the flood estimates for Wilson County. When the COE gives Wilson County accurate estimates, the flood levels will be adjusted accordingly. Until values are released for Wilson County, flood levels will be based upon Hartsville, Tennessee in order to plan for a worst-case scenario.

The Corps of Engineers has given a projected timeframe of 19 hours before water levels along the Cumberland River will begin to rise in Wilson County. Water levels are projected to rise at over a

half foot an hour and will continue to rise at this rate for over 160 hours. (Estimates vary based upon conflicting information in relation to Wilson County released by the Corps of Engineers). The waters will rise at approximately eight inches per hour. The current along the river is projected to flow 11.3 mph.

The lake level at Wolf Creek Dam was reported to be 703 feet MSL on February 26, 2006. The Corps of Engineers has stated that the lake level will be raised to summer pool for the next two years until construction begins to repair the leaks. Estimates of failure on the dam have been

given as high as 15% and as low as 1%. Because if any chance of failure exists, no matter how remote, an emergency operations plan must be developed. Additionally, the threat of domestic or international acts of terrorism against the dam must also be taken into consideration given the large amount of media coverage being allotted to the dam in recent months and the tremendous and unprecedented economic impact it would have on numerous counties along the Cumberland River, including Metropolitan Davidson County, Tennessee. (Pg.5 WCEM).

II. PURPOSE

The Committee discussed numerous options in attempting to anticipate the potential consequences and dangers of such a major disaster and prepare for such without expending major amounts for buying supplies and equipment that hopefully will go unused.

The plan provides HIYC members with an action plan that can be administered by a small a group (action team) of HIYC members within the initial 24-hour warning phase of dam failure.

The rapid implementation of the plan is essential to reduce the amount of damage to HIYC property and members’ boats.

It is essential that the plan be updated annually until the danger is past, which is anticipated to be in the year 2014 when the COE expects to complete work on the project.

This emergency plan was made to prepare the HIYC Sailing Community to:

1. Have a plan in place that will provide an organized step-by-step approach to deal with the consequences of failure to the Wolf Creek Dam failure when notified by the WEMA.

2. Lessen damage to HIYC docks, piers, and moorings.

3. Facilitate the required clean -up to HIYC and the harbor.

4. Diminish the long-term effects of post dam failure to the HIYC sailing community.

III. PRELIMINARY DAMAGE ESTIMATES FOR WILSON COUNTY

The damage estimates for Wilson County are as follows and are based on the dam failing at max flood stage (492 feet MSL):

1. Major highways and roads will be cut-off including Route 109,

2. Nonaville Road, Saundersville Road, North Green Hill Road, US 70 by Cedar Creek, Mays Chapel, HWY 109, Cooks Road, Cairo Bend, Academy, Horn Springs, and others.

3. Widespread power outages will occur throughout Wilson County.

4. Drinking water will be contaminated and residents reliant upon alternate clean water sources (e.g., bottled, boiled, etc.).

5. Over 2,600 homes will be flooded (some completely submerged)

6. Hazardous materials problems that will include gas stations under water, propane tanks breaking loose and floating free, ruptured natural gas lines, stores that carry batteries and other hazardous materials that will be underwater, and other unknown caches of hazardous materials stored in or near homes and businesses that will be flooded, etc.

7. Evacuation of residents from flood zones as well as evacuating residents who are dependent on power for health reasons and are at facilities or homes that do not possess alternate power sources.

8. Locking down the hospital to emergency patients only.

9. Transporting all non-critical medical patients out of Wilson County.

10. Competing with Metro Davidson for emergency resources.

11. Overstressing of emergency personnel resources that will be necessary 24/7 for at least two weeks with the potential for a more extended period of time on top of the everyday emergencies that will continue to occur and that are unrelated to the flooding problem.

12. Providing alternate housing for displaced residents until their homes can be repaired or rebuilt.

13. Economic loss to businesses and schools being closed for extended periods of time.

14. Accelerated wear and tear on county vehicles and equipment resulting in replacement needs prior to when county finances will allow.

IV. PRELIMINARY DAMAGE ESTIMATES TO HIYC AND HARBOR

1. The four major docks would break free from their anchors.

2. Moorings in the harbor would break from the anchor chain or drag the anchor.

3. Harbor Drive road would be under water including the causeway.

4. The dinghy and part of the north lot would be under water.

5. The harbor will be the recipient of many types of debris that would inhibit the movement of boats in the harbor and require eventual clean-up of the waterway.

6. Floodwater would occupy space under the Clubhouse.

VI. Wilson County Emergency Management Command Post Location and Communication.

1. WEMA Station # 4 will utilize the HAZMAT frequency (alternate is VTAC). Evacuation orders and directions to Emergency Locations may be found on pp.13 & 14 of the WCEM Emergency Operations Guideline.

2. Lakeview Elementary School 6211 Sandersville Rd. (Staging Area).

3. Security and management of traffic control points is the responsibility of the Wilson County Sheriff Office. Only members with identification for the HIYC Emergency Team will be permitted access to HIYC.

VII. Docks. Dock Admirals and their team members will shut Power and Water Supply off to each dock. Each dock will be tied-off to fixed objects on shore since it is anticipated the docks will float their anchors.

VIII. MOORINGS. Members with boats on moorings will be requested to ensure that a spare line is stowed in the anchor compartment (may include the anchor line) to permit emergency team to extend the mooring line for each boat.

IX. ACCESS TO HIYC. Access to HIYC will be limited to members who serve on the “emergency team.” The Wilson County Sheriffs Office will be responsible for controlling access to HIYC.

X. TELEPHONE SERVICE. Because most public (land & cell) phone service will be out the Committee is working with Wilson County EMS and others to procure an alternate phone system.

XI. WATER SUPPLY. Water will be cut-off to each dock and at SOS located next to Tiki Hut.

XII. HARBOR SIDE OF PROPERTY. Boats located in the DINGHY LOT will be moved to top of hill parking area. NORTH LOT. All boats will be secured (tied-off) to trees. LASERS. Boats will be secured (tied-off) to storage rack. All related hardware for the fleet is to be removed and stored in a safe place prior to 24-hour notice of failure

XIII. WASTE PUMP-OUT STATION. System needs to be disconnected and moved to high ground.

XIV. CLUBHOUSE STORAGE AREA ON GROUND FLOOR. Items stowed to be need moved, including OPTIS.

9. Dumpster and vendor trash cans will be secured to adjacent trees (Fielder).

XVII. HIYC FLOOD LEVEL EXPECTATION ILLUSTRATION.

The following Drawing illustrates the different levels of flood waters should the Dam fail. The various levels of the lake have been painted on the lower level of the Main Clubhouse (North or Lakeside) as well on the Dinghy Lot Crane. These numbers indicate the different elevations of an increase in water levels at HIYC. These elevation markings are taken from the Normal Pool level of the lake as per COE.

The normal Old Hickory Lake Summer pool level is said to be 442 MSL Therefore, a notification of Dam Failure at a given level at the Wolf Creek Dam will set the expected level the flood waters will be when they arrive at HIYC.

Example: The COE gives notification of Dam failure when the dam is at 452 MSL, which would be ten feet above the normal Summer Pool level. The 10 foot rise, according to the diagram on the next page, will have water rising to the HIYC driveway level or the floor level of the main clubhouse with elevation of 443 feet. (See page 12).

CENTER HILL DAM UPDATE, Addition to HIYC Wolf Creek Dam Failure

Emergency Plan

Date: December 10, 2007

TO: HARBOR ISLAND BOARD OF GOVERNOR’S

On September 9, 2007 The Tennessean printed a report on the possible failure of the Center Hill Dam. In general, the U.S. Corps of Engineers and an Independent Panel reported that the failure is based on similar results found in the Wolf Creek Dam(WCD) report and that being the eroding limestone with sink holes or other gaps under and around the more than 55 year old Center Hill Dam(CHD). The study states any failure probably would happen as a result of growing weaknesses in the earth and rock hillsides beside the dam, rather than as a result of the dam itself.

Those in the greatest danger are along the Caney Fork River in Carthage, South Cartage, and Lancaster, TN where lives could be lost in an eight-hour worst – case scenario. A $ 309 million project to fix WCD is under way with similar funding anticipated for CHD.

Planning for WCD has provided the capability to notify county residents of a pending disaster through a variety of means, including “reverse 911” calls that take an hour or less to execute. Maps outlining flood levels for CHD failure are available at the WEMA offices in Lebanon. Water from Wolf Creek would take 15 to 16 hours to reach Wilson County, but Center Hill water would take only a few.

Important Note: The current target level for Center Hill Dam is between 623.5 and 640 feet. Today the level was 625.39, however the lake may gain as much as 15 feet per day during periods of heavy rain fall.
