About this dam

Morris Mill Pond (South Division Street)

Morris Mill Pond, located in Wicomico, Maryland, is a picturesque water resource that serves as a local recreational hub. Built in 1947, this earth dam stands at a height of 11.9 feet and spans 241 feet in length, with a storage capacity of 191 acre-feet. The pond is primarily used for irrigation and recreation purposes, offering a tranquil setting for residents and visitors to enjoy activities such as fishing and boating.

Despite its serene appearance, Morris Mill Pond is classified as having a high hazard potential, which necessitates regular inspections and maintenance to ensure its structural integrity. Fortunately, the dam's condition assessment in 2021 deemed it satisfactory, with a risk assessment rating of moderate. The dam has undergone modifications in 2018 to enhance its hydraulic and structural features, further ensuring the safety of the surrounding community. With its proximity to Slab Bridge Creek and a drainage area of 5.1 square miles, Morris Mill Pond remains a vital water resource in the region.

In the event of an emergency, an Emergency Action Plan (EAP) is in place, last revised in April 2022, to meet established guidelines and provide necessary information to emergency contacts. With its role in irrigation and recreation, Morris Mill Pond serves as a valuable asset to the community, showcasing the importance of responsible water resource management in the face of changing climate conditions.

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 Morris Mill Pond (South Division Street)

Where does the data for Morris Mill Pond (South Division Street) 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.
