About this dam

Lenhart Lowell

Lenhart Lowell is a privately owned dam located in Guthrie, Oklahoma, along the TR-Cottonwood River. It was completed in 1965 and stands at a height of 15 feet with a length of 475 feet. The dam serves a primary purpose of "Other" and is classified as an Earth dam with a Stone core and Soil foundation. It has a maximum storage capacity of 60 acre-feet and a normal storage of 25 acre-feet, covering a surface area of 5 acres.

Despite being categorized as having a low hazard potential, Lenhart Lowell is considered to have a very high risk due to its proximity to residential areas and potential impact in case of failure. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspections, with the last inspection conducted in August 2011. It has a controlled spillway with a width of 1 foot and is equipped with one valve as an outlet gate. The dam is located within the jurisdiction of Logan County and is situated at a distance of 19 miles from the city of Guthrie.

With its unique design and important role in water resource management, Lenhart Lowell serves as a significant structure in Oklahoma's infrastructure. Enthusiasts of water resources and climate will find this dam's construction details and risk assessment data intriguing, shedding light on the complexities of managing and maintaining critical infrastructure in the face of changing environmental conditions.

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 Lenhart Lowell

Where does the data for Lenhart Lowell 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.
