Coastal Dam D dam
Coastal Dam D
Coastal Dam D, located in Newton, Texas, was completed in 1957 and serves as a vital water supply structure along the West Branch White Oak Creek. This privately owned earth dam stands at 22 feet in height and stretches 360 feet in length, with a storage capacity of 95 acre-feet. Despite being a non-federal structure, Coastal Dam D is subject to state permitting and inspection requirements to ensure its operational safety.
With a primary purpose of water supply, Coastal Dam D plays a crucial role in managing water resources in the region. Although lacking a spillway, the dam's structural integrity and hazard potential have been rated as high, indicating the importance of ongoing risk assessment and management measures. The condition assessment of the dam remains unrated, highlighting the need for continued monitoring and maintenance to ensure its long-term functionality and safety for both local communities and the surrounding environment.
Overall, Coastal Dam D stands as a key infrastructure asset in the region's water resource management system, providing essential storage capacity and regulatory oversight. As climate change impacts continue to pose challenges to water availability and quality, the maintenance and upkeep of structures like Coastal Dam D become increasingly vital in safeguarding against potential risks and ensuring sustainable water management practices for future generations.

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 Coastal Dam D
Where does the data for Coastal Dam D 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.
