Roy Lee Carmack dam
Roy Lee Carmack
Located in Grundy, Missouri, the Roy Lee Carmack dam was completed in 1990 by the USDA NRCS with a primary purpose of grade stabilization along the TR-MEDICINE river. This earth dam stands at 27 feet high and stretches 354 feet in length, providing a storage capacity of 23 acre-feet for fire protection, stock, or small fish pond purposes. With a drainage area of 120 acres, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Despite being privately owned, the Roy Lee Carmack dam falls under the jurisdiction of the Rock Island District and is not regulated by the state of Missouri. With a spillway width of 10 feet and no outlet gates, the dam poses a moderate risk level of 3 according to the provided data. While the structure has not been inspected since January 1990, it is designed to withstand potential emergencies, although specific emergency action plans and risk management measures are not outlined.
Water resource and climate enthusiasts will be intrigued by the design and function of the Roy Lee Carmack dam, which serves multiple purposes and plays a crucial role in maintaining water levels along the TR-MEDICINE river. The dam's strategic location in Chula, Missouri, and its low hazard potential make it a key component in the region's water management infrastructure. The data provided offers a glimpse into the dam's specifications, its history, and its current risk assessment, highlighting the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in safeguarding the surrounding area from potential flooding events.

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 Roy Lee Carmack
Where does the data for Roy Lee Carmack 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.
