Johnson Creek Dam 4-8-2e dam
Johnson Creek Dam 4-8-2e
Johnson Creek Dam 4-8-2e, located in Saline, Nebraska, serves as a crucial structure for local wildlife conservation efforts. Completed in 1991, this earth dam stands at 35 feet tall and spans 929 feet in length, with a primary purpose of creating a fish and wildlife pond. The dam has a normal storage capacity of 134 acre-feet, providing essential habitat for various species in the area.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Johnson Creek Dam 4-8-2e has a low hazard potential and is currently in satisfactory condition as of the last assessment in 2016. Despite its modest scale, the dam plays a significant role in maintaining ecological balance in the region, with a drainage area of 3.8 square miles and a maximum discharge capacity of 140 cubic feet per second. The dam's location along Sand Creek enhances its importance as a valuable resource for water and climate enthusiasts in the area.
With its strategic placement and effective design, Johnson Creek Dam 4-8-2e exemplifies the intersection of environmental stewardship and infrastructure development. As a focal point for fish and wildlife preservation, this dam underscores the importance of sustainable water resource management in the face of climate change challenges. Its role in supporting local ecosystems and enhancing biodiversity serves as a testament to the critical role that such structures play in promoting resilience and adaptation in the face of evolving environmental conditions.

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 Johnson Creek Dam 4-8-2e
Where does the data for Johnson Creek Dam 4-8-2e 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.
