About this dam

Hexton Farms

Hexton Farms, located in Cecil County, Maryland, is a private recreational dam with a low hazard potential that was completed in 1966. The dam, standing at a height of 15 feet and with a length of 520 feet, serves the primary purpose of providing a fish and wildlife pond for recreational activities. Situated on Hall Creek, the dam has a storage capacity of 90 acre-feet and a surface area of 10 acres, making it an ideal spot for outdoor enthusiasts to enjoy nature.

Managed by the Maryland Dam Safety regulatory agency, Hexton Farms undergoes regular inspections to ensure its structural integrity and safety. The dam features an uncontrolled spillway with a width of 150 feet, capable of handling a maximum discharge of 2100 cubic feet per second. Despite its moderate risk assessment rating, the dam is deemed to be in good condition as of the latest assessment in April 2021. With its picturesque setting and recreational amenities, Hexton Farms is a popular destination for water resource and climate enthusiasts seeking a peaceful retreat in Fredericktown, Maryland.

Overall, Hexton Farms stands as a testament to responsible dam construction and management, providing a safe and enjoyable environment for visitors to appreciate the intersection of water resources and natural beauty. Its history, design, and purpose make it a valuable asset in the conservation and enjoyment of Maryland's waterways, embodying the harmony between human recreation and environmental stewardship in the face of climate challenges.

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.

FAQ

About Hexton Farms

Where does the data for Hexton Farms 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.

Premium feature
