Bear Creek Watershed Site 51 dam
Bear Creek Watershed Site 51
Bear Creek Watershed Site 51, located in Quandahl, Iowa, is a key site for flood risk reduction along the TR-South Bear Creek. Constructed in 2005 by the USDA NRCS, this earth dam stands at a height of 30 feet and spans 240 feet in length, with a storage capacity of 25 acre-feet. The primary purpose of this dam is flood risk reduction, serving not only to protect the local community but also to manage water resources effectively in the area. With a low hazard potential and a moderate risk assessment rating, this site plays a crucial role in mitigating potential flood damage and ensuring the safety of the surrounding area.
Despite not being state regulated, Bear Creek Watershed Site 51 is a significant asset in the region, with its stone core and soil foundation contributing to its structural integrity. The dam's uncontrolled spillway, with a width of 10 feet, further enhances its ability to manage water flow during heavy rainfall events. While the dam's condition is currently not rated, its location in a high-risk area underscores the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in flood risk reduction efforts. This site serves as a testament to the collaborative efforts of local government and federal agencies in safeguarding water resources and enhancing climate resilience in the Bear Creek Watershed.
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 Bear Creek Watershed Site 51
Where does the data for Bear Creek Watershed Site 51 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.
