About this dam

Lake Meade Dam

Lake Meade Dam in Suffolk, Virginia, is a gravity dam that serves as a crucial water supply source for the region. With a height of 25 feet and a storage capacity of 9,281 acre-feet, the dam plays a vital role in managing water resources in the area. Despite its importance, the dam is classified as having a high hazard potential and a poor condition assessment, highlighting the need for regular inspections and maintenance to ensure its continued functionality.

The dam, located on the Nansemond River, is regulated by the Virginia Department of Conservation and Recreation and undergoes regular inspections to assess its structural integrity. With a surface area of 590 acres and a drainage area of 64.4 square miles, Lake Meade Dam provides essential water storage for the surrounding community. However, the dam's condition assessment and hazard potential underscore the importance of ongoing risk management measures to mitigate any potential threats to the dam and surrounding areas.

As a primary water supply structure, Lake Meade Dam plays a critical role in providing water for residents and businesses in Suffolk, Virginia. With its proximity to the Nansemond River and Cedar Lake, the dam's strategic location enhances its ability to store and distribute water effectively. Despite its high hazard potential and poor condition assessment, efforts to maintain and monitor the dam ensure that it continues to fulfill its primary purpose of water supply for the community.

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 Lake Meade Dam

Where does the data for Lake Meade Dam 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.
