Schmidt Rd No.1 dam
Schmidt Rd No.1
Schmidt Rd No.1 is a privately owned earth dam located in Mellette, South Dakota, with a primary purpose that remains unspecified. Completed in 1963, this structure stands at a height of 26 feet and spans a length of 455 feet, providing a storage capacity of 110 acre-feet with a normal storage level of 67 acre-feet. The dam, situated on the TR Little White Offstream, falls under the regulatory jurisdiction of the South Dakota Department of Environment and Natural Resources.
Despite its age, Schmidt Rd No.1 boasts a low hazard potential and has not been rated for its current condition. While no specific inspection or maintenance information is available, the dam is subject to state permitting, inspection, and enforcement. Managed by the Natural Resources Conservation Service, this structure serves as a crucial component in the local water resource infrastructure, contributing to flood control and water storage in the region.
Water resource and climate enthusiasts interested in the role of dams in managing water supplies and mitigating flood risks would find Schmidt Rd No.1 an intriguing case study. With its modest dimensions and regulatory oversight, this earth dam represents a vital piece of South Dakota's water management infrastructure, demonstrating the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in safeguarding the local community and environment.

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 Schmidt Rd No.1
Where does the data for Schmidt Rd No.1 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.
