About this dam

Upper Tansil Dam

Upper Tansil Dam, located in Carlsbad, New Mexico, along the Pecos River, was completed in 1893 and serves as a crucial water resource for the area. The dam, primarily owned by the local government, has a primary purpose of recreation and boasts a concrete structure with a height of 22 feet and a length of 585 feet. With a normal storage capacity of 550 acre-feet and a maximum storage of 617 acre-feet, the dam plays a significant role in managing water resources in the region.

Despite its historical significance and recreational value, Upper Tansil Dam is facing challenges in terms of its condition assessment, which has been rated as poor. The hazard potential associated with the dam is considered significant, and the risk assessment has been classified as moderate. The dam's last inspection in February 2019 revealed the need for immediate attention and potential risk management measures to ensure the safety and stability of the structure.

As water resource and climate enthusiasts monitor the state-regulated Upper Tansil Dam, it is evident that proactive measures need to be taken to address its poor condition and significant hazard potential. With its critical role in water management and recreation, stakeholders must prioritize the dam's maintenance and risk mitigation strategies to safeguard both the environment and the surrounding communities that rely on its services.

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 Upper Tansil Dam

Where does the data for Upper Tansil 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 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.
