Little Sni-A-Bar #29 dam
Little Sni-A-Bar #29
Little Sni-A-Bar #29 is a vital earth dam located in Lafayette, Missouri, designed by the USDA NRCS and completed in 1972. 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.

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.
- 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.
- 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.
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, environmental 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.

About Little Sni-A-Bar #29
Where does the data for Little Sni-A-Bar #29 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
