About this dam

Angel Lake Dam Lower

Angel Lake Dam Lower, located in Guthrie, Forsyth County, North Carolina, is a privately owned earth dam constructed in 1962 on Smith Creek. With a structural height of 14 feet and a hydraulic height of 11 feet, this dam serves multiple purposes, including providing 72 acre-feet of storage capacity and controlling a drainage area of 2,413 acres. The dam has a low hazard potential and was last inspected in November 2013, with a fair condition assessment.

Despite not being state-regulated or permitted, Angel Lake Dam Lower is equipped with state-inspected operations. It falls under the jurisdiction of the Wilmington District of the US Army Corps of Engineers and is situated in the congressional district represented by Virginia Foxx. Although no spillway type or outlet gates are specified, the dam's primary function remains essential for water resource management in the region.

Water and climate enthusiasts will appreciate the historical significance and environmental impact of Angel Lake Dam Lower, given its role in regulating water flow and storage in the area. The dam's location on Smith Creek and its proximity to the city of Guthrie make it a vital infrastructure for maintaining water security and flood control measures. Despite its low hazard potential, ongoing monitoring and maintenance ensure the dam's continued effectiveness in water resource management for the surrounding 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 Angel Lake Dam Lower

Where does the data for Angel Lake Dam Lower 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.
