Moon Lake Dam dam
Moon Lake Dam
Moon Lake Dam, located in Grimes County, Texas, is a privately owned Earth dam built in 1975 with a primary purpose of "Other." Standing at a height of 12 feet and spanning 680 feet in length, this dam has a storage capacity of 50 acre-feet and serves as a crucial structure on Floyds Creek. Despite being non-federally regulated, the dam is subject to state permitting and inspection, ensuring its safety and compliance with regulations.
With a risk assessment rating of "High (2)," Moon Lake Dam's hazard potential and condition assessment are not available, indicating a need for further evaluation and potential risk management measures. The dam does not have a spillway and is equipped with one outlet gate. The presence of associated structures, inspection dates, and emergency preparedness information is not readily available, highlighting the importance of continued monitoring and assessment to ensure the dam's safety and stability for water resource and climate enthusiasts in the area.
As a significant feature in the local water infrastructure, Moon Lake Dam serves as a reminder of the importance of maintaining and monitoring dams for water resource management and climate resilience. Its location in a high-risk area underscores the need for proactive risk management and emergency preparedness measures to mitigate potential hazards and ensure the safety of surrounding communities and the environment. Further data and assessments are needed to fully understand the dam's condition and potential risks, emphasizing the ongoing need for comprehensive dam safety practices in the region.
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.

About Moon Lake Dam
Where does the data for Moon Lake 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.
