About this dam

Marimont Lower

Marimont Lower, also known as Taylor Lake Dam, is a private-owned structure located in McDowell, North Carolina. Built in 1965, this earth dam on Muddy Creek serves primarily for recreational purposes, offering a serene escape in the city of Glenwood. Standing at a structural height of 20 feet and boasting a hydraulic height of 15 feet, Marimont Lower has a maximum storage capacity of 40 acre-feet, with a normal storage level of 15 acre-feet across its 365-foot length.

Despite its age, Marimont Lower has been well-maintained, with a satisfactory condition assessment as of its last inspection in April 2014. Considered to have a significant hazard potential, this dam is under state regulation and is subject to regular inspections, permitting, and enforcement by the North Carolina Dam Safety Program. While no specific spillway or outlet gate information is provided, the dam's risk management measures and emergency preparedness status remain undisclosed as of the latest data update in April 2021.

For water resource and climate enthusiasts, Marimont Lower offers a fascinating glimpse into the intersection of human engineering with natural landscapes. Its role in providing recreational opportunities while also necessitating careful oversight and maintenance underscores the delicate balance between harnessing water resources for human benefit and ensuring the safety and sustainability of our environment. As efforts to manage and mitigate potential risks associated with dams like Marimont Lower continue to evolve, understanding the intricacies of their design, operation, and regulation becomes increasingly crucial in safeguarding both communities and ecosystems.

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 Marimont Lower

Where does the data for Marimont 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 Significant 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.
