Lake Mark Dam Dam
Lake Mark Dam
Located in Polk, Texas, Lake Mark Dam stands as a testament to human ingenuity and engineering prowess. Completed in 1964, this private earth dam serves a primary purpose of recreation, offering a serene oasis for water resource and climate enthusiasts to appreciate. With a height of 23 feet and a length of 1219 feet, Lake Mark Dam holds a normal storage capacity of 129 acre-feet and a maximum storage of 290 acre-feet, providing both a functional and scenic reservoir.
The dam, situated on the TR-West Fork Double Branch, boasts a fair condition assessment as of February 2018, ensuring its structural integrity and safety for visitors. Despite lacking a spillway, the dam's risk assessment is deemed high, indicating the need for proactive risk management measures. With its picturesque surroundings and recreational opportunities, Lake Mark Dam offers a unique blend of natural beauty and human innovation for all to enjoy.
As water management becomes increasingly crucial in the face of climate change, Lake Mark Dam serves as a reminder of the importance of sustainable resource utilization. From its historical construction to its current state of operation, this dam symbolizes the harmonious coexistence between nature and human development, making it a must-visit destination for those passionate about water conservation and environmental stewardship.

About Lake Mark Dam
Where does the data for Lake Mark 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.
Dam data reference
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.
