Gerdes Lake No 1 Dam dam
Gerdes Lake No 1 Dam
Gerdes Lake No 1 Dam, located in Lee County, Texas, was completed in 1957 and serves primarily for irrigation purposes. The dam, designed by USDA NRCS, is classified as an Earth dam with a height of 13 feet and a length of 660 feet. It has a storage capacity of 53 acre-feet, with a normal storage level of 37 acre-feet. The dam is situated on the TR-Nails Creek and is under the jurisdiction of the state of Texas.
Although the dam does not have a spillway and is not regulated by the state, it poses a high risk according to the risk assessment conducted, with a hazard potential that is not available. The condition of the dam is currently not rated and there is no emergency action plan prepared. Despite these factors, the dam continues to play a crucial role in supporting irrigation activities in the area. With its unique design and purpose, Gerdes Lake No 1 Dam remains a significant structure for water resource management in the region.
Water resource and climate enthusiasts will find Gerdes Lake No 1 Dam to be an intriguing structure, given its historical significance and the various purposes it serves, including fire protection, stock, and irrigation. While facing some risk and lacking certain regulatory oversight, the dam continues to be a vital component of the local water infrastructure. Its design and construction by USDA NRCS reflect a commitment to efficient water management practices in the region.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Gerdes Lake No 1 Dam
Where does the data for Gerdes 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.
