About this dam

Pocomoke City Sewage Lagoon No.1 (North Pond)

Pocomoke City Sewage Lagoon No.1 (North Pond) in Worcester, Maryland, stands as a vital water resource managed by the local government and regulated by the Maryland Dam Safety agency. Built in 1972 by Rummel, Klepper and Kahl, this earthen dam serves a primary purpose of recreation while also supporting irrigation needs in the area. With a maximum storage capacity of 250 acre-feet and a normal storage of 37 acre-feet, the dam covers a surface area of 45 acres and has a drainage area of 0.1 square miles.

Despite its low hazard potential, the dam's risk assessment is rated as very high (1), signifying the need for vigilant monitoring and management. The last inspection conducted in July 2016 revealed a condition assessment of "Not Rated," prompting a call for further evaluation and potentially a reassessment of its maintenance needs. The controlled spillway, with a width of 2 feet, helps manage maximum discharges of up to 10 cubic feet per second, ensuring the safety and stability of the dam structure. As a key element in the local water infrastructure, Pocomoke City Sewage Lagoon No.1 plays a crucial role in water management and environmental protection efforts in the region.

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.

FAQ

About Pocomoke City Sewage Lagoon No.1 (North Pond)

Where does the data for Pocomoke City Sewage Lagoon No.1 (North Pond) 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.
