EMERGENCY ACTION PLAN

KINION LAKE

MUDDY FORK OF ILLINOIS RIVER, SITE 1

PURPOSE:

The purpose of this emergency action plan (EAP) is to safeguard the lives and property of individuals that are located below the KINION LAKE-- Muddy Fork of Illinois River Watershed, Site 1, located in Washington County, Arkansas, in the event of heavy rainfall resulting in emergency spillway flows or structural problems that might result in failure of the dam.

DESCRIPTION OF THE DAM:

Site Number 1 is a floodwater control structure built under the PL-566 program by the USDA Natural Resources Conservation Service, formerly the Soil Conservation Service. Site 1 was designed and constructed as a moderate hazard class structure, and is currently classified as a high hazard class dam. The site is in the southeast quarter of Section 21, Township 16 N, Range 32 W; Longitude 94.3800, Latitude 36.0503 (Rhea Quad). Site 1 has a dam height of 36 feet, a normal surface area of 12 acres, and a total storage volume of 957 acre-feet.

ATTACHED ARE:

1. County vicinity map

2. Topographic map

3. Aerial photo of site and impacted area downstream

4. Plan and section view of structure

EMERGENCY IDENTIFICATION, EVALUATION, AND CLASSIFICATION

An emergency exists when the dam is in danger of failing (overturning or breaching) or when excessively high water behind the dam indicates flooding either above or below the dam (or both) may threaten life or property. An emergency is identified by one or more of the following conditions:

Excessive flow through the spillway

Excessive rainfall either occurring or predicted.

Excessive seepage either through the dam or at the toe.

Cracks in the dam.

Movement or change in alignment of the dam.

Evaluation of the emergency involves determining when conditions are sufficient to activate an Emergency Action Plan (EAP). Emergencies may be classified according to the severity of the situation and the required response. There are three conditions that warrant action by responsible parties. Condition 1: Flooding is occurring or is expected to occur; Condition 2: Potential emergency situation has developed; Condition 3: Failure is imminent.

CONDITIONS THAT WARRANT ACTION BY RESPONSIBLE PARTIES

Condition 1

Flooding is occurring or is expected to occur

This condition occurs when significant rainfall has filled the lake and emergency spillway flow is anticipated. This will result in flooding of the impacted downstream residences.

A. The designated observers will assess the lake area to determine the potential hazard. They will follow

the notification list on page ___of this report.

B. Notify homeowners if flooding is occurring or is anticipated.

Condition 2

Potential emergency situation has developed

This situation occurs when the dam has developed a structural condition that would jeopardize its integrity. Examples include seepage downstream, leaking pipe under the dam, small slides on the slopes, erosion through, beneath, or around the embankment. Imminent failure of the structure is not anticipated. The following action will be taken.

Natural Resources Conservation Service staff will assess the lake area to determine the potential

hazard. They will follow the notification list on ____ of this report.

B. Corrective measures will be taken to eliminate the threat to the structure.

C. If the situation deteriorates, the emergency will be upgraded to a Condition 3.

Conditions Triggering a Condition 2: Potential emergency situation has developed

Problem	How to Evaluate

Flooding	a. Spillway releases.

Seepage	a. Excessive or increasing seepage through the dam or at the toe of the dam. Water is

observed to be seeping through the dam where little or no seepage was previously

detected. Flow is increasing with time.

b. Seepage through the dam or at the toe is muddy

Cracking or

Deformities	a. Cracks are detected

b. Large slides at or near the abutments have formed or are forming.

Emergency Message for Condition 2

The following is the notification message to be relayed by telephone or radio from one level to the next:

KINION LAKE DAM IS BEING MONITORED. AT THIS TIME, NO EVACUATIONS ARE NEEDED. IF CONDITIONS WORSEN, YOU WILL BE NOTIFIED.

Emergency no longer exists message

A SERIOUS SITUATION AT KINION LAKE DAM NO LONGER EXISTS.

Condition 3

Failure is imminent

This situation occurs when major structural damage has occurred and failure of the dam is expected. The following action will be taken.

A. The designated observers will follow the notification list on _____ of this report.

Homeowners and businesses will be notified by the Washington County Sheriff’s Office to evacuate

their homes or places of business.

The conservation district will implement equipment and materials to minimize the damage to the structure and downstream properties.

Condition Triggering a Condition 3: Failure is Imminent

Problem	How to Evaluate

Flooding	a. Large spillway releases.

Seepage	a. Excessive or rapidly increasing seepage through the dam or at the toe of the dam.

Flow is rapidly increasing with time.

b. Seepage through the dam or at the toe is muddy or discharge is increasing.

Cracking or

Deformities	a. Cracks are suddenly forming or enlarging at a rapid rate.

Large slides have or are forming and appear to create a significant weakness to the

dam.

c. The alignment of the dam appears to have shifted or is currently shifting.

Emergency Message for Condition 3

The following is the notification message to be relayed by telephone and radio from one level to the next:

AN EMERGENCY EXISTS AT KINION LAKE, EVACUATE IMMEDIATELY.

Emergency no longer exists message

AN EMERGENCY SITUATION AT KINION LAKE DAM NO LONGER EXISTS. YOU MAY RETURN TO YOUR HOMES.
