Gosper dam
Gosper
Gosper, located in Grundy, Tennessee, is a private earth dam primarily used for fire protection, stock, or as a small fish pond. With a structural height of 15 feet and a storage capacity of 77 acre-feet, this dam on TRIBJONATHAN CREEK serves a critical role in water resource management in the area. Despite not being state-regulated or permitted, Gosper poses a significant hazard potential and has a moderate risk assessment rating.
Although last inspected in September 2016, Gosper has not been rated for its condition assessment, and no emergency action plan (EAP) has been prepared. The dam has an inspection frequency of five years, highlighting the importance of regular monitoring and maintenance to ensure its integrity and safety. With no outlet gates and an uncontrolled spillway type, it is essential for stakeholders to remain vigilant in assessing and managing any potential risks associated with this structure.
As climate change continues to impact water resources and infrastructure, the management of dams like Gosper becomes increasingly vital. With a risk management plan yet to be established and a lack of inundation maps and emergency contacts, there is a need for proactive measures to enhance the resilience of this dam and mitigate potential threats. As enthusiasts in water resource and climate adaptation, it is crucial to advocate for the proper maintenance and monitoring of structures like Gosper to safeguard communities and ecosystems from the growing challenges 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 Gosper
Where does the data for Gosper 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 Significant 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.
