Summary
The dam, standing at a height of 41 feet and stretching 550 feet in length, serves as a crucial flood risk reduction structure for the local area, with a primary purpose of debris control and flood risk reduction. With a storage capacity of 134 acre-feet and a drainage area of 740 acres, the dam plays a significant role in managing water resources in the region.
Despite its low hazard potential and satisfactory condition assessment, the dam undergoes regular inspections every five years to ensure its safety and effectiveness. The dam's spillway, with a width of 40 feet, assists in managing water discharge during peak flow events. The surrounding area benefits from the dam's presence, with a normal storage capacity of 90 acre-feet and a surface area of 10 acres. Overall, Little Sni-A-Bar #29 is a critical infrastructure piece for flood control and water resource management in the region, contributing to the overall climate resilience of the area.
Managed by local government authorities and regulated by the DAM AND RESERVOIR SAFETY PROG, Little Sni-A-Bar #29 represents a collaborative effort between state and federal agencies to enhance water resource management and climate adaptation strategies. The dam's structure, built on a stone core and soil foundation, showcases a commitment to sustainable infrastructure development. With its strategic location along the TR-LITTLE SNIABAR CR, the dam serves as a key component in the broader network of flood risk reduction measures in Missouri, highlighting the importance of integrated water resource management in addressing climate-related challenges.

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.
