Mount Laurel (Mud Run) dam
Mount Laurel (Mud Run)
Mount Laurel (Mud Run) is a local government-owned dam located in New Castle Township, Pennsylvania. Built in 1879, it stands at a height of 39 feet and has a length of 1124 feet, with a primary purpose of water supply. The dam holds a storage capacity of 852 acre-feet, with a normal storage level of 622 acre-feet. It is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure its structural integrity.
The dam's spillway type is uncontrolled, with a spillway width of 55 feet. It has a high hazard potential due to its location along the Mud Run river and a moderate risk assessment score of 3. Despite this, the dam's condition assessment is rated as satisfactory, indicating that it is currently in good operational condition. The dam has seen modifications in 2005, 2013 for hydraulic and structural improvements, and is deemed to meet regulatory guidelines for emergency action preparedness.
Water resource and climate enthusiasts will find Mount Laurel (Mud Run) to be an essential piece of infrastructure for water supply in the Schuylkill County area. Its historical significance, combined with its modern regulatory oversight and risk management measures, make it a fascinating subject for those interested in the intersection of water management, environmental protection, and climate resilience.
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 Mount Laurel (Mud Run)
Where does the data for Mount Laurel (Mud 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.
