About this dam

Henrietta City Reservoir No 1

Henrietta City Reservoir No 1, located in Clay County, Texas, is a vital water resource infrastructure designed primarily for water supply. Completed in 1912, this earth dam structure stands at a height of 24 feet and has a storage capacity of 557 acre-feet, with a normal storage capacity of 380 acre-feet. Despite its age, the dam is still in good condition and meets the necessary state regulatory standards for inspection, permitting, and enforcement by the Texas Commission on Environmental Quality (TCEQ).

With a history dating back over a century, Henrietta City Reservoir No 1 has provided a reliable source of water to the local community. The dam structure, classified as an earth dam with a buttress core type, spans a length of 1285 feet and stands as a testament to early 20th-century engineering and water management practices. Despite being not regularly inspected since 1981, the dam has been deemed to have a high risk potential (2) by the authorities, emphasizing the need for continued monitoring and maintenance to ensure its safety and longevity.

As climate change continues to impact water resources and infrastructure, the significance of maintaining and assessing structures like Henrietta City Reservoir No 1 becomes increasingly important. With its historical value and continued function as a water supply source, the reservoir serves as a reminder of the vital role that well-maintained dams play in ensuring water security for communities. Ongoing risk management measures and adherence to regulatory guidelines will be crucial in preserving this essential piece of water infrastructure for future generations.

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 Henrietta City Reservoir No 1

Where does the data for Henrietta City Reservoir No 1 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 Not Available 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.
