About this dam

Helm Lake No 2 Dam

Located in Hopkins, Texas, Helm Lake No 2 Dam stands as a testament to engineering excellence. Completed in 1964, this earth dam with a buttress core reaches a height of 23 feet and spans 600 feet in length. With a primary purpose of recreation, the dam provides a storage capacity of 184 acre-feet and covers a surface area of 15 acres, making it a popular destination for water resource and climate enthusiasts.

Regulated by the Texas Commission on Environmental Quality, Helm Lake No 2 Dam is subject to state inspections, permitting, and enforcement. Despite its high hazard potential rating, the dam's condition remains unrated, highlighting the need for ongoing risk management measures. While lacking a spillway, the dam features one outlet gate for water release. With a risk assessment indicating high risk, Helm Lake No 2 Dam serves as a critical water resource for the surrounding area.

As part of the Fort Worth District, the dam is a vital component of the local infrastructure. While its hazard potential and risk assessment pose challenges, the dam's role in providing recreation opportunities and water storage cannot be understated. With its picturesque location and impressive design, Helm Lake No 2 Dam is a captivating destination for those interested in water resources and climate resilience.

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 Helm Lake No 2 Dam

Where does the data for Helm Lake No 2 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 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.

Premium feature

Favorites and alerts are part of Snoflo Premium. Save reservoirs, set storage thresholds, and get push notifications when conditions cross.
