Frd No T-4 dam
Frd No T-4
Frd No T-4, also known as the Walnut Creek Watershed Dam T 4, is a vital structure located in Brown County, Kansas, with the primary purpose of flood risk reduction. Built in 1964 by the USDA NRCS, this earth dam stands at 40 feet tall and spans 1000 feet in length, providing essential protection for the surrounding area. With a drainage area of 2.01 square miles and a maximum discharge capacity of 972 cubic feet per second, this dam plays a crucial role in managing water flow and debris control in the region.
Despite its importance, Frd No T-4 is currently classified as having a high hazard potential and poor condition assessment. The last inspection in November 2018 revealed areas in need of improvement, highlighting the urgency for maintenance and upgrades to ensure the dam's continued effectiveness. With a moderate risk level and a history of state regulation and inspection, there is a clear need for proactive risk management measures and emergency preparedness to safeguard the community and environment in case of any unforeseen events.
As water resource and climate enthusiasts, it is essential to recognize the significance of structures like Frd No T-4 in protecting communities from the impacts of flooding. By staying informed about the condition of dams like this one and advocating for necessary improvements and maintenance, we can contribute to the resilience of our water infrastructure and enhance our ability to adapt to a changing climate. Let us work together to support the safety and sustainability of water resources 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 Frd No T-4
Where does the data for Frd No T-4 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 High 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.
