Summary
Built in 1992, this earth-type dam stands at a height of 25.4 feet and spans a length of 600 feet, providing a normal storage capacity of 15 acre-feet. The dam is situated on the CROSS CREEK-TR river/stream, with a drainage area of 0.31 square miles and a maximum discharge capacity of 348 cubic feet per second.
Despite being classified as having a low hazard potential, Dd No 111 is considered to have a moderate risk level. The dam has not been rated for its condition assessment and does not have an emergency action plan in place. With a spillway width of 40 feet and uncontrolled spillway type, the dam's risk management measures and inundation maps are currently not prepared or updated. However, the dam has not been modified in recent years and is not under the jurisdiction or regulation of the state.
Overall, Dd No 111 serves as a crucial infrastructure for flood risk reduction in the area, highlighting the importance of proper maintenance and monitoring to ensure its continued safety and functionality. For water resource and climate enthusiasts, this dam presents an opportunity to study the intersection of engineering, environmental conservation, and disaster mitigation in the context of water management and infrastructure development.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
