Panorama Silt Dam Site 2 dam
Panorama Silt Dam Site 2
Panorama Silt Dam Site 2, located in Guthrie County, Iowa, is a privately owned earth dam with a primary purpose of sediment retention. Built in 1988 by the Soil Conservation Service (SCS), this dam stands at a height of 35 feet and spans a length of 1100 feet, creating a storage capacity of 114 acre-feet. With a low hazard potential and moderate risk assessment, the dam is regulated and inspected by the Iowa Department of Natural Resources to ensure its safety and functionality.
Situated on the TR-Lake Panorama stream, this dam plays a vital role in managing water resources in the area, with a drainage area of 0.52 square miles and a surface area of 5.9 acres. Despite its uncontrolled spillway type, the dam poses low risk and has not undergone a condition assessment. The surrounding community of Lake Panorama benefits from the water storage and sediment retention capabilities of Panorama Silt Dam Site 2, contributing to overall water resource management in the region.
With its strategic location and design by the SCS, Panorama Silt Dam Site 2 serves as a key infrastructure for water management in Guthrie County, Iowa. As climate change continues to impact water resources, this dam stands as a critical asset for sediment control and water storage, ensuring the resilience of the local ecosystem. The dam's moderate risk assessment underscores the importance of regular inspection and maintenance to uphold its functionality and safeguard the surrounding community from potential hazards.

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 Panorama Silt Dam Site 2
Where does the data for Panorama Silt Dam Site 2 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.
