Indspec No 2 dam
Indspec No 2
Indspec No 2 is a private earth dam located in Petrolia Borough, Butler, Pennsylvania, along the South Branch of Bear Creek. Built in 1950 for grade stabilization, this dam stands at a height of 27 feet and spans 360 feet in length, with a storage capacity of 37 acre-feet. Despite its age, the dam's condition is rated as satisfactory, with a high hazard potential due to its location and purposes.
Managed by the Pennsylvania Department of Environmental Protection, Indspec No 2 undergoes regular inspections, with the last one conducted in October 2020. While no emergency action plan (EAP) is currently in place, the dam meets regulatory guidelines and has not experienced any recent modifications. The risk assessment and management measures for this dam are currently unspecified, but its location and condition suggest a need for ongoing monitoring and potential updates to its emergency preparedness.
Water resource and climate enthusiasts interested in the sustainability and safety of dams like Indspec No 2 can appreciate the detailed data available on its design, construction, and regulatory oversight. As a critical infrastructure for water management and flood control, this dam serves as a reminder of the importance of proactive maintenance and monitoring to ensure the long-term integrity of our water resources in the face of evolving climate challenges.

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 Indspec No 2
Where does the data for Indspec No 2 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 High 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.
