R G Struble Lake (Pa-431)
Located in Honey Brook Township, Pennsylvania, R G Struble Lake (Pa-431) is a local government-owned reservoir designed by the USDA NRCS and regulated by the Pennsylvania Department of Environmental Protection. Completed in 1971, this earth dam stands at 31 feet high and spans a length of 1500 feet, with a storage capacity of 2880 acre-feet for flood risk reduction. The dam also serves recreational purposes, offering a surface area of 146 acres for outdoor enthusiasts to enjoy.
Managed by the Natural Resources Conservation Service, R G Struble Lake boasts a satisfactory condition assessment and a high hazard potential, prompting regular inspections every year to ensure its structural integrity. The reservoir is situated along the East Branch Brandywine Creek, within the Chester County region, and serves as a vital water resource for the surrounding community. Despite its age, the dam has undergone modifications in 2005 and 2008 to meet modern safety standards, reflecting a commitment to safeguarding both the environment and public safety.
With its strategic location and crucial role in flood risk reduction, R G Struble Lake (Pa-431) stands as a testament to effective water resource management in Pennsylvania. As a popular destination for both recreational activities and environmental conservation, this earth dam continues to play a key role in preserving the watershed and enhancing the quality of life for local residents. Its blend of functionality and beauty makes it a must-visit site for water resource and climate enthusiasts seeking to witness sustainable infrastructure in action.
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 R G Struble Lake (Pa-431)
Where does the data for R G Struble Lake (Pa-431) 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.
