Prairie Cr. No. B-3-1 (Montgomery) dam
Prairie Cr. No. B-3-1 (Montgomery)
Prairie Creek No. B-3-1, also known as Montgomery Lake Dam, is a vital structure located in Montgomery, Indiana. Built in 1965 by the USDA NRCS, this earth dam stands at a height of 27 feet and stretches 590 feet in length. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential water damage. With a storage capacity of 321 acre-feet and a drainage area of 0.44 square miles, this dam plays a crucial role in managing water resources in the region.
The dam's condition assessment in 2012 rated it as "fair," with a significant hazard potential. Despite this, it is regularly inspected every three years to ensure its structural integrity and safety. The dam's high risk assessment level (2) underscores the importance of ongoing risk management measures to mitigate any potential threats. With no spillway and no outlet gates, the dam relies on its design and construction to effectively manage water flow and reduce flood risks in the area.
Overall, Prairie Creek No. B-3-1 is a key infrastructure in the region, regulated by the IDNR and serving as a crucial element in flood risk reduction efforts. Its historical significance, combined with its ongoing maintenance and inspection, highlights the importance of water resource management and climate resilience in safeguarding communities against natural disasters. As a focal point for water enthusiasts and climate advocates, this dam stands as a testament to the critical role infrastructure plays in protecting our environment and communities.
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 Prairie Cr. No. B-3-1 (Montgomery)
Where does the data for Prairie Cr. No. B-3-1 (Montgomery) 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 Significant 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.
