Collier Lake Dam dam
Collier Lake Dam
Collier Lake Dam in Erath, Texas, stands as a vital structure for water supply in the region, completed in 1960 with a height of 47 feet and a storage capacity of 320 acre-feet. Situated on Henshaw Creek, this earth dam with a buttress core serves a primary purpose of water supply, supporting the local community with a normal storage capacity of 237 acre-feet. Despite its critical role in water management, the dam lacks a spillway and is designated as having a high risk potential, underscoring the importance of regular inspections and risk management measures.
Owned privately, Collier Lake Dam falls under state jurisdiction with permitting and inspection responsibilities delegated to the state regulatory agency in Texas. The dam's condition is currently not rated, highlighting the need for ongoing maintenance and assessment to ensure its structural integrity and safety. With no federal funding or oversight, the dam's operation and management are solely the responsibility of the private owner, emphasizing the importance of proactive measures to mitigate potential hazards and protect the surrounding community and environment.
As a key component of the local water infrastructure, Collier Lake Dam plays a crucial role in water supply management for the region. With its historical significance and continued impact on the surrounding area, the dam serves as a reminder of the importance of sustainable water resource management and the need for ongoing monitoring and maintenance to ensure its continued functionality and safety in the face of changing climate 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.

About Collier Lake Dam
Where does the data for Collier Lake 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.
