Two Mile Run dam
Two Mile Run
Two Mile Run, also known as Justus Lake, is a local government-owned water resource in Venango, Pennsylvania, managed by the USDA NRCS. This flood risk reduction dam was completed in 1971 and stands at a height of 84.6 feet, providing storage for 6300 acre-feet of water. The dam serves the dual purpose of flood risk reduction and recreation, offering a surface area of 144 acres for outdoor activities.
Located in Sugarcreek Borough, Two Mile Run is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure its fair condition and high hazard potential are managed effectively. The dam's primary designer is the Natural Resources Conservation Service, and it falls under the jurisdiction of the Buffalo District. With a drainage area of 8.4 square miles, the dam plays a crucial role in protecting the surrounding area from flooding events and providing opportunities for recreational activities for the community.
Two Mile Run is a significant water resource in Venango County, Pennsylvania, with a long-standing history of flood risk reduction efforts. As a vital structure in the region, it is closely monitored and inspected to uphold safety standards and ensure its continued effectiveness in managing water flow and protecting the local environment. Climate and water resource enthusiasts will appreciate the careful regulation and management of Two Mile Run, highlighting the importance of sustainable water infrastructure in adapting to changing climate patterns and safeguarding communities from potential hazards.

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 Mile Run
Where does the data for Two Mile Run 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.
