Frd No Gs 30 dam
Frd No Gs 30
Frd No Gs 30, also known as Walnut Creek Watershed Dam Gs 30, is a flood risk reduction structure located in Hamlin, Kansas. Built in 1965 by the USDA NRCS, this buttress dam stands at 30 feet in height and spans 560 feet in length. It serves the primary purpose of flood risk reduction within the Terrapin Creek-TR watershed, with a storage capacity of 70 acre-feet and a spillway width of 40 feet.
Managed by the local government and regulated by the Kansas Department of Agriculture, Frd No Gs 30 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While it has not been modified in recent years, it undergoes regular state inspections and enforcement to ensure its functionality and safety. With a comprehensive emergency action plan in place and updated contact information, this dam plays a crucial role in protecting the surrounding community from potential flood events.
For water resource and climate enthusiasts, Frd No Gs 30 serves as an essential infrastructure in managing flood risks and protecting the environment in Brown County, Kansas. Its construction and maintenance highlight the collaborative efforts between federal agencies, local governments, and regulatory bodies to safeguard communities and mitigate the impacts of extreme weather events. As the world faces increasing challenges from climate change, structures like Frd No Gs 30 play a vital role in enhancing resilience and adaptation strategies for a sustainable future.

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 Gs 30
Where does the data for Frd No Gs 30 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 Low 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.
