Twin Arrow No 3 Dam dam
Twin Arrow No 3 Dam
Twin Arrow No 3 Dam, located in Collin, Texas, is a private-owned structure designed by the USDA NRCS and completed in 1970. This earth-type dam stands at a height of 27 feet with a length of 362 feet, providing a storage capacity of 30 acre-feet. Situated on the TR-STOVER CREEK, the dam serves as a vital resource for water management in the region.
Operated under the regulatory oversight of the TCEQ, Twin Arrow No 3 Dam plays a crucial role in flood control and water supply for the surrounding area. With a high-risk assessment rating, the dam's condition has not been officially rated, highlighting the importance of regular inspections and maintenance to ensure its structural integrity and safety. Despite the lack of a spillway, this dam remains an essential component of the local water infrastructure, contributing to the sustainable management of water resources in the region.
As a key feature in the Fort Worth District's water management system, Twin Arrow No 3 Dam showcases the collaborative efforts between private owners, government agencies, and designers to address water resource challenges. With its historical significance and ongoing role in safeguarding against floods and ensuring water availability, this dam stands as a testament to the importance of sustainable water management practices in the face of climate change and increasing water demands.

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 Twin Arrow No 3 Dam
Where does the data for Twin Arrow No 3 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.
