Koy Dam dam
Koy Dam
Koy Dam, located in Rosenberg, Texas, is a private earth dam designed by USDA NRCS for the primary purpose of serving as a Fish and Wildlife Pond. Completed in 1979, this dam stands at a height of 23 feet and has a length of 751 feet, providing a storage capacity of 124 acre-feet. The dam is regulated and inspected by the Texas Commission on Environmental Quality (TCEQ) to ensure its safety and compliance with state regulations.
Despite its relatively small size, Koy Dam plays a crucial role in providing fire protection, stock, and recreational opportunities in the area. It is situated on TR-Bullinger Creek and is part of the Austin, Texas watershed, covering a drainage area of 0.34 square miles. Although the dam currently does not have a spillway, it is equipped with outlet gates to manage water levels. The risk assessment for this dam is classified as high (2), emphasizing the importance of regular inspections and maintenance to prevent any potential hazards.
Overall, Koy Dam serves as a vital water resource and habitat for wildlife in the region, highlighting the intersection of water conservation and environmental stewardship. As climate change continues to impact water availability and quality, dams like Koy Dam play a crucial role in managing water resources and supporting ecosystems. It is essential for stakeholders and enthusiasts to stay informed and engaged in the preservation and sustainable management of dams like Koy Dam to ensure a resilient and healthy water future for all.

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 Koy Dam
Where does the data for Koy 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.
