G-3 Pond dam
G-3 Pond
G-3 Pond, located in Clinton, Iowa, is a privately owned earth dam structure designed by the USDA NRCS in 1971. This small pond serves multiple purposes, including fire protection and stock or small fish pond. With a dam height of 27 feet and a storage capacity of 34 acre-feet, G-3 Pond covers a surface area of 3 acres and drains a 0.07 square mile watershed.
Despite being rated as having a low hazard potential and a moderate risk level, G-3 Pond has not been inspected or assessed for its condition. The dam features an uncontrolled spillway and is regulated by the Iowa DNR. It is situated near the Wapsipinicon River and Tr-Brophy Creek, making it an important water resource for the surrounding area. The pond's location and design make it a valuable asset for both water conservation and climate management efforts in the region.
Overall, G-3 Pond stands as a testament to the importance of small-scale water infrastructure in supporting various ecological and human needs. As climate change continues to impact water resources, structures like G-3 Pond play a crucial role in mitigating risks and ensuring sustainable water management practices. With its strategic location, diverse purposes, and regulatory oversight, G-3 Pond exemplifies the intersection of water resource management and climate resilience in the heart of Iowa.

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 G-3 Pond
Where does the data for G-3 Pond 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.
