Attoyac Bayou Ws Nrcs Site 23a Dam dam
Attoyac Bayou Ws Nrcs Site 23a Dam
Located in Nacogdoches, Texas, the Attoyac Bayou WS NRCS Site 23a Dam stands as a testament to effective flood risk reduction measures in the region. Built in 2006 by the USDA NRCS, this earth dam on NACONICHE CREEK boasts a height of 59 feet and a length of 1605 feet, providing essential protection to the surrounding area. With a storage capacity of 27,225 acre-feet, the dam plays a crucial role in managing water resources and protecting against potential flooding events.
Managed by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the dam is regularly inspected and maintained to ensure its structural integrity. The dam's spillway, with a width of 405 feet, helps manage excess water flow during heavy rainfall, while its outlet gates include a slide and two uncontrolled gates. The dam's satisfactory condition assessment in 2017 reflects the ongoing commitment to its upkeep and the safety of the community it serves.
With a moderate risk rating, the Attoyac Bayou WS NRCS Site 23a Dam continues to be a vital piece of infrastructure for flood risk reduction and recreation in the area. As climate change brings about more extreme weather events, the importance of well-maintained dams like this one cannot be overstated. For water resource and climate enthusiasts, this dam serves as a reminder of the crucial role that infrastructure plays in protecting communities and managing the impacts of a changing climate.
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 Attoyac Bayou Ws Nrcs Site 23a Dam
Where does the data for Attoyac Bayou Ws Nrcs Site 23a 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.
