Two Bar Two Grazing Association Dam dam
Two Bar Two Grazing Association Dam
The Two Bar Two Grazing Association Dam, also known as the Cleveland Dam, is a privately-owned earth dam located in South Dakota. Completed in 1994, this dam serves as a vital water resource for the surrounding area, with a storage capacity of 250 acre-feet and a normal storage level of 36 acre-feet. Situated on a tributary of Snake Creek, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), the Two Bar Two Grazing Association Dam is subject to state regulations, permitting, inspection, and enforcement. With a height of 14 feet and a length of 600 feet, this dam plays a crucial role in water management and flood control in the region. The dam has a maximum discharge rate of 1743 cubic feet per second, ensuring the safety and stability of the structure during periods of high water flow.
Owned and operated by a private association, the Two Bar Two Grazing Association Dam is a key component of the water infrastructure in Edmunds County, South Dakota. With its strategic location and efficient design, this dam contributes to the conservation of water resources and helps mitigate the impact of climate variability on the local ecosystem. As a noteworthy example of sustainable water management practices, this dam stands as a testament to the importance of responsible stewardship of our natural resources in the face of changing environmental conditions.

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 Two Bar Two Grazing Association Dam
Where does the data for Two Bar Two Grazing Association 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.
