Running Hare Vineyard Lake dam
Running Hare Vineyard Lake
Running Hare Vineyard Lake, also known as Bowens Farm Pond, is a private water resource located in Calvert, Maryland. Managed by the USDA NRCS, this earth dam was completed in 1970 and serves primarily for recreational purposes. With a height of 20 feet and a length of 300 feet, the dam has a storage capacity of 91 acre-feet, providing a surface area of 6.8 acres for visitors to enjoy.
Despite its low hazard potential, the dam's condition was assessed as unsatisfactory in April 2021. Regular inspections are conducted, with the last one taking place in July 2021, and a seismic modification was carried out in 2014. The spillway, with a width of 2 feet, is uncontrolled, and the maximum discharge capacity is 205 cubic feet per second. The risk assessment for this structure is moderate, with a DSAC (Dam Safety Action Classification) not yet assigned.
Water resource and climate enthusiasts visiting Running Hare Vineyard Lake can appreciate the beautiful surroundings and recreational opportunities it offers. With its unique location in Williams Wharf along the Cypress Swamp-TR, this private dam provides a serene setting for outdoor activities and relaxation. While the dam's condition may raise some concerns, ongoing inspections and risk management measures help ensure the safety and enjoyment of those who visit this picturesque water resource in Maryland.

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 Running Hare Vineyard Lake
Where does the data for Running Hare Vineyard Lake 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 Low 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.
