Ninth Parallel dam
Ninth Parallel
Ninth Parallel, also known as Schwabacher No. 1, is a private dam located in Sublette, Wyoming, specifically in the city of Daniel. Completed in 1972, this Earth-type dam serves multiple purposes, including fire protection, stock watering, and small fish pond management. With a height of 25 feet and a length of 400 feet, Ninth Parallel has a storage capacity of 250 acre-feet and covers a surface area of 20 acres, drawing water from Spring Creek.
Despite being classified as a low-hazard structure with fair condition assessment, Ninth Parallel is regulated and inspected by the Wyoming State Engineer's Office. It features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 489 cubic feet per second. The dam has a drainage area of 2.7 square miles and plays a crucial role in managing water resources in the region, highlighting the intersection of water management and climate resilience in the face of changing environmental conditions.
While Ninth Parallel has not undergone recent modifications, its risk assessment indicates a moderate level of risk, underscoring the importance of ongoing monitoring and management measures. With Liz Cheney as the Congressional representative for the area, the dam serves as a vital infrastructure for water supply and wildlife conservation, embodying the intricate balance between human needs and environmental protection in the context of water resource management and climate adaptation efforts.
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 Ninth Parallel
Where does the data for Ninth Parallel 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.
