Managed by the Maryland Dam Safety regulatory agency, Lake Kittamaqundi has a low hazard potential and is considered to be in satisfactory condition as of the latest assessment in April 2021. The spillway, with a width of 270 feet, allows for controlled water discharge, while the surrounding Little Patuxent River adds to the natural beauty of the area. With a drainage area of 27.5 square miles, the lake serves as a vital water resource for the community.

For water resource and climate enthusiasts, Lake Kittamaqundi offers a glimpse into the importance of sustainable water management and recreational opportunities in urban areas. Its peaceful waters and surrounding greenery provide a sanctuary for wildlife and visitors alike, showcasing the harmonious relationship between human development and environmental preservation. As a key feature of the Howard County landscape, this beloved lake continues to be a symbol of responsible stewardship and community engagement in water conservation efforts.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
