About this dam

Gillespie Pond Dam

Gillespie Pond Dam, also known as Mitchell Pond Dam #6, is a private dam located in Pineville, North Carolina. Built in 1968, this earth dam stands at a structural height of 15 feet and a hydraulic height of 11 feet, creating a reservoir with a normal storage capacity of 57 acre-feet and a maximum storage of 68 acre-feet. The dam is primarily used for recreational purposes, offering a tranquil spot for water resource and climate enthusiasts to enjoy the surrounding Four Mile Creek-Os river and stream.

Despite being privately owned, Gillespie Pond Dam is subject to state inspections to ensure its safety and structural integrity. The dam has a low hazard potential and is currently rated in fair condition as of its last assessment in October 2018. With a drainage area of 429 square miles and a maximum discharge capacity of 99 cubic feet per second, the dam plays a vital role in managing water resources in the region. Enthusiasts interested in water resource management and climate resilience can appreciate the significance of this dam in the local ecosystem.

As a recreational structure in Mecklenburg County, Gillespie Pond Dam offers visitors a picturesque setting for outdoor activities and serves as a prime location for observing the intersection of water resources and climate dynamics. While not under federal regulation, the dam's maintenance and inspection remain important aspects to ensure its continued safe operation and contribution to the surrounding environment. Passionate individuals interested in water resource management and climate adaptation can find inspiration in the sustainable use of this dam for recreational and environmental purposes.

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 Gillespie Pond Dam

Where does the data for Gillespie Pond 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 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.
