About this dam

Mackie Tyler Dam

Mackie Tyler Dam, located in Orangeburg, South Carolina, stands as a crucial structure along the TR-North Fork Edisto River. Completed in 1955, this private-owned Earth-type dam serves primarily for recreational purposes, offering a serene escape for water resource and climate enthusiasts. With a structural height of 18 feet and a length of 560 feet, the dam boasts a storage capacity of 80 acre-feet, contributing to the conservation efforts in the region.

Despite its fair condition assessment and high hazard potential, Mackie Tyler Dam undergoes regular inspections to ensure its safety and functionality. The South Carolina DHEC oversees the regulatory and enforcement aspects, while the Savannah District of the US Army Corps of Engineers stands as the federal agency responsible for the dam. The dam's emergency action plan is continuously updated to meet guidelines, enhancing preparedness in case of any unforeseen events. With its historical significance and vital role in recreation and conservation, Mackie Tyler Dam remains a notable landmark in the water resource landscape of South Carolina.

As water enthusiasts continue to appreciate the beauty and functionality of Mackie Tyler Dam, its presence serves as a testament to the importance of responsible dam management and maintenance. With a focus on safety and environmental sustainability, this Earth-type dam symbolizes the harmonious coexistence between human activities and natural resources. As climate change impacts water resources worldwide, the conservation efforts at Mackie Tyler Dam highlight the significance of proactive measures in ensuring the resilience and longevity of vital infrastructure in the face of evolving environmental challenges.

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 Mackie Tyler Dam

Where does the data for Mackie Tyler 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.
