J Olson Grade Stabilization Dam dam
J Olson Grade Stabilization Dam
The J Olson Grade Stabilization Dam, located in Homer, Nebraska, serves as a crucial structure for managing water resources in the area. Constructed in 2009 by the USDA NRCS, this earth dam stands at a height of 25 feet and has a length of 550 feet, providing storage for up to 44 acre-feet of water. Designed to regulate the flow of TR-Fiddlers Creek, this dam plays a vital role in flood control and erosion prevention along the waterway.
Despite its significance in water management, the J Olson Dam is currently in poor condition, with a low hazard potential. The Nebraska Department of Natural Resources regulates and inspects the dam regularly to ensure its effectiveness and safety. With a drainage area of 0.4 square miles and a maximum discharge capacity of 210 cubic feet per second, this dam is a valuable asset in protecting the surrounding area from water-related risks.
Enthusiasts of water resources and climate resilience will appreciate the role of the J Olson Grade Stabilization Dam in maintaining the ecological balance of the region. With its earth and stone construction, this dam stands as a testament to sustainable water management practices. As efforts continue to improve its condition and safety measures, this structure remains a key component in safeguarding the local community from the impacts of water-related events.

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 J Olson Grade Stabilization Dam
Where does the data for J Olson Grade Stabilization Dam 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.
