Lake Mary Dam dam
Lake Mary Dam
Lake Mary Dam, located in Anderson, Texas, stands as a testament to engineering ingenuity and a hub for recreational activities. Built in 1945, this earth dam stretches 600 feet in length and reaches a height of 28 feet, providing a storage capacity of 370 acre-feet. The dam, situated on Rucker Branch, serves as a popular destination for water resource and climate enthusiasts seeking a tranquil setting for outdoor adventures.
While the dam lacks a spillway and has not been assessed for potential hazards, it boasts a normal storage capacity of 196 acre-feet and covers a surface area of 21 acres. Despite its age, Lake Mary Dam continues to be a focal point for recreational purposes, offering visitors a serene environment for fishing, boating, and other leisure activities. Managed by a private entity, the dam has not undergone recent inspections, but its structural integrity remains intact for the enjoyment of visitors.
With a high risk assessment rating of 2, Lake Mary Dam presents a unique blend of historical significance and contemporary appeal. As a popular recreation spot in Texas, this dam serves as a reminder of the crucial role that water resources play in shaping our environment. Whether for leisurely picnics by the waterfront or insightful discussions on climate change, Lake Mary Dam offers a picturesque backdrop for engaging with nature and appreciating the beauty of water management systems.

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 Lake Mary Dam
Where does the data for Lake Mary 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.
