Prince George's County Government is the Owner of six High Hazard Dams within the County, and is responsible for the routine monitoring, inspection, and maintenance of the dams. The six dams are listed below and each dam has an Emergency Action Plan that reduces the risk of human life loss and injury and minimizes property damage during an unusual or emergency event. -- Laurel Lakes -- Indian Creek #2 -- Indian Creek #3 -- Lake Arbor -- Largo Town Center -- Heritage Glen
There are three emergency levels. Emergency Level 1 This is a non-emergency, unusual event, slowly developing, e.g., the elevation of the dam is rising. Technical representatives/inspectors are sent out to monitor the dam for a potential or imminent dam failure situation. Emergency Level 2 Potential dam failure situation, rapidly developing. Technical representatives/inspectors closely monitor the condition of the dam and periodically report the status of the situation to the Dam Operator. If the conditions worsen and dam failure is imminent, the Dam Operator immediately notifies the Emergency Management Director of the change, and if necessary, recommends full or partial activation of the Emergency Operations Center. Emergency Level 3 Urgent, dam failure appears to be imminent or in progress. This is an extremely urgent situation when the failure cannot be prevented. The Dam Operator will immediately contact the Emergency Management Director to put plans in place for evacuation of all at risk people, and close all roads that will be affected.
Pre-Event Dam Inspections
In case a significant storm event is forecast, the Dam Operator will send out qualified technical representatives/inspectors to each dam to monitor the dam performance during the storm event and to advise the Dam Operator should an emergency occur. They will constantly monitor the water surface elevation and report back to the Dam Operator.
