Roxbury dam
Roxbury
Located in Franklin County, Pennsylvania, the Roxbury dam stands on the Conodoguinet Creek, serving as a crucial structure for water supply in the region. Owned and regulated by the Pennsylvania Department of Environmental Protection, this concrete gravity dam boasts a height of 60 feet and a length of 450 feet, providing a storage capacity of 1936 acre-feet. With a surface area of 54 acres and a drainage area of 33.8 square miles, Roxbury plays a vital role in ensuring water availability for the surrounding communities.
Despite its fair condition assessment and high hazard potential, Roxbury has been deemed safe for operation, with regular inspections conducted as per state regulations. The dam's emergency action plan status and risk assessment remain unclear, but its role in safeguarding the water supply for Letterkenny Township underscores its importance in the local ecosystem. As enthusiasts of water resources and climate, monitoring Roxbury's condition and management measures will be crucial to ensure its continued operation and resilience in the face of changing environmental conditions.
As a key infrastructure for water supply in Pennsylvania, Roxbury represents a significant asset that requires ongoing maintenance and monitoring. With its location on the Conodoguinet Creek and its role in serving the surrounding communities, Roxbury stands as a testament to the importance of sustainable water resource management in the face of climate challenges. Enthusiasts in the field can appreciate the complexities of managing dams like Roxbury and the critical role they play in ensuring water security for both current and future generations.

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 Roxbury
Where does the data for Roxbury 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.
