Lake Marburg dam
Lake Marburg
Lake Marburg in York, Pennsylvania is a private water resource managed by the Pennsylvania Department of Environmental Protection. This man-made reservoir was completed in 1967 and serves as a recreational hub with a surface area of 1275 acres and a storage capacity of 53,100 acre-feet. The dam, standing at 107 feet in height, regulates the flow of the WEST BRANCH CODORUS CREEK and has a high hazard potential.
Despite its high hazard potential, Lake Marburg boasts a satisfactory condition assessment and undergoes regular inspections. The dam is primarily used for recreational purposes, attracting water resource and climate enthusiasts alike. Situated in Heidelberg Township, the reservoir provides a scenic backdrop for outdoor activities and is a vital water source for the surrounding community. Its location in the Baltimore District adds to its appeal for visitors and researchers interested in water resource management.
Overall, Lake Marburg is a significant water resource in Pennsylvania with a rich history dating back to its completion in 1967. Its strategic location, ample storage capacity, and recreational offerings make it a valuable asset for both the local community and water resource enthusiasts. With a focus on safety and regular inspections, this private reservoir continues to play a crucial role in water management and climate resilience efforts in the region.

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 Lake Marburg
Where does the data for Lake Marburg 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.
