Lake Manr Dam dam
Lake Manr Dam
Lake Manr Dam in Rusk, Texas, is a privately owned structure built in 1949 for recreational purposes. The dam, standing at 38 feet tall and stretching 720 feet in length, harnesses the waters of Walker Branch to create a reservoir with a storage capacity of 1053 acre-feet. The dam's spillway, with a width of 250 feet, allows for the controlled release of excess water to prevent flooding in the surrounding area.
Managed by the Texas Commission on Environmental Quality (TCEQ), Lake Manr Dam underwent significant modifications in 2007 to enhance its hydraulic, mechanical, and structural components. Despite its age, the dam's condition is currently not rated, with a moderate risk assessment level of 3. The dam has not been classified with a hazard potential, indicating its stable and secure state. Regular inspections and maintenance ensure the safety and functionality of this vital water resource for both recreation and local water management needs.
Lake Manr Dam serves as a vital water resource for the region, providing recreational opportunities and water storage for the community. Its strategic location and efficient design make it an essential component of the local water infrastructure, contributing to the overall water management system in Rusk, Texas. As climate change continues to impact water resources, the maintenance and upkeep of structures like Lake Manr Dam are crucial for ensuring water security and resilience in the face of changing environmental 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 Lake Manr Dam
Where does the data for Lake Manr 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.
