Cj Gerlach Dam Dam
Cj Gerlach Dam
Cj Gerlach Dam, located in Polk, Texas, along the Sally Creek, is a private earth dam that was completed in 1960 for recreational purposes. Standing at 19 feet high and 500 feet long, this dam has a storage capacity of 280 acre-feet and an uncontrolled spillway with a width of 100 feet. Despite being privately owned, the state of Texas regulates and inspects the dam to ensure its safety and functionality.
The dam, designed as a buttress-type structure, has two uncontrolled outlet gates and is primarily used for recreation. While the hazard potential of the dam is currently listed as "Not Available" and its condition remains unrated, a moderate risk assessment has been assigned to the site. With no recent inspection data since 1999, the dam's emergency action plan status and risk management measures are currently unknown, highlighting the need for updated assessments and monitoring to ensure the safety of the surrounding community and environment.
Cj Gerlach Dam, nestled in a picturesque location, plays a crucial role in providing recreational opportunities to the local residents and visitors. However, with its age and limited inspection history, the importance of regular assessments and maintenance to mitigate potential risks and ensure the long-term stability of the dam cannot be overstated. Efforts to update emergency action plans, enhance risk management measures, and conduct comprehensive inspections are essential to safeguarding this vital water resource and preserving its recreational value for future generations.

About Cj Gerlach Dam
Where does the data for Cj Gerlach 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 below 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.

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.
