Little Sni-A-Bar Wtrsd #33 Dam dam
Little Sni-A-Bar Wtrsd #33 Dam
Little Sni-A-Bar Watershed #33 Dam, located in Lafayette County, Missouri, is a local government-owned structure designed by the USDA NRCS and completed in 1977. With a primary purpose of flood risk reduction, this earth dam stands at a height of 36 feet and spans 600 feet in length, holding a storage capacity of 75 acre-feet. The dam, situated on the TR Little Sni-A-Bar Creek, serves to protect the surrounding area from potential flooding events.
Despite its low hazard potential and satisfactory condition assessment, the dam is regulated by the Missouri DAM AND RESERVOIR SAFETY PROG, with state permitting, inspection, and enforcement in place to ensure its safe operation. The spillway, of a width of 20 feet, is uncontrolled, allowing for a maximum discharge of 192 cubic feet per second. The dam's location within the Kansas City District, under the jurisdiction of Emanuel Cleaver, provides further insight into its significance in the local water resource management and climate resilience efforts.
In summary, Little Sni-A-Bar Watershed #33 Dam serves as a vital infrastructure for flood risk reduction in the region, with a history dating back to the late 1970s. Its design, construction, and ongoing maintenance highlight the collaborative efforts between federal agencies, local government, and regulatory bodies to ensure the safety and functionality of this essential water resource structure. For water resource and climate enthusiasts, this dam represents a key component of the broader watershed management strategies in place to safeguard communities from the impacts of extreme weather events.
Dam data reference
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 Wtrsd #33 Dam
Where does the data for Little Sni-A-Bar Wtrsd #33 Dam 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.
