Shannon Clark Dam dam
Shannon Clark Dam
Shannon Clark Dam, located in Gregg County, Texas, is a private-owned structure built in 2000 with a primary purpose of serving as an Earth-type dam on Glade Creek. Standing at a height of 20 feet and a length of 186 feet, the dam has a storage capacity of 25 acre-feet and is designed with an uncontrolled outlet gate. Despite its modest size, the dam poses a high risk (Level 2) according to risk assessment, although the hazard potential and condition assessment are not available.
Operated by private owners, Shannon Clark Dam is not regulated by the state but does undergo regular inspections. The dam, with its buttress core type and unlisted/unknown foundation, lacks a spillway and locks. While it serves a primarily "other" purpose, the dam's location on Glade Creek highlights its significance in managing water resources in the area and mitigating flood risks. The dam's presence in the Fort Worth District adds to its importance in the region's water resource management efforts.
Overall, Shannon Clark Dam stands as a critical infrastructure in the water resource system of Gregg County, Texas. Despite its small size, the dam plays a significant role in maintaining water levels and potentially mitigating flood risks in the area. As climate change continues to impact water resources, structures like Shannon Clark Dam will become increasingly vital in ensuring the sustainability and resilience of the region's water supply and infrastructure.

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 Shannon Clark Dam
Where does the data for Shannon Clark 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.
