About this dam

Spencer Water Supply

Spencer Water Supply is a crucial local government-owned water resource in Van Buren, Tennessee, situated along the Caney Fork River. This earth dam, completed in 1965, stands 38 feet tall and spans 480 feet, with a storage capacity of 358 acre-feet and a normal storage level of 220 acre-feet. The dam's purpose is primarily for water supply, serving as a vital source for the surrounding community.

Managed by the Tennessee Safe Dams Program, Spencer Water Supply is subject to state regulation, inspection, and enforcement to ensure its structural integrity and operational safety. Despite being classified as having a significant hazard potential, the dam's condition assessment deemed it satisfactory as of January 2021. With a moderate risk rating, risk management measures are in place to address potential issues and protect the surrounding area in case of emergencies.

Water resource and climate enthusiasts will appreciate the strategic importance of Spencer Water Supply in providing reliable water access to the local population. Its location along the Caney Fork River and its operational history since the 1960s highlight the significance of this earth dam in sustaining the community's water needs. The dam's compliance with state regulations and its risk management measures underscore the commitment to maintaining its safety and functionality for the benefit of all stakeholders involved.

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 Spencer Water Supply

Where does the data for Spencer Water Supply 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.
