Woodlawn Lake No 1 Dam dam
Woodlawn Lake No 1 Dam
Woodlawn Lake No 1 Dam, located in Grayson, Texas, was completed in 1972 and serves primarily for irrigation purposes. This earth dam with a height of 18 feet and a length of 710 feet stands on the TR-Iron Ore Creek. While it does not have a spillway, the dam boasts a storage capacity of 60 acre-feet, with a normal storage level of 24 acre-feet.
Although the dam's hazard potential is listed as "Not Available" and its condition assessment is "Not Rated," the risk assessment indicates a high risk level of 2. Despite being privately owned and not regulated by the state, the dam undergoes regular state inspections. With no associated structures, Woodlawn Lake No 1 Dam stands as an essential resource for irrigation and recreation in the area.
Water resource and climate enthusiasts will find Woodlawn Lake No 1 Dam an intriguing structure, especially given its unique design features such as the buttress core type. The dam's location on TR-Iron Ore Creek, along with its significant storage capacity, adds to its importance in the region. While the dam's risk level may raise concerns, the regular state inspections ensure its safety and functionality for the community it serves.

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 Woodlawn Lake No 1 Dam
Where does the data for Woodlawn Lake No 1 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.
