Catwalk dam
Catwalk
Catwalk is a privately owned irrigation dam located in Sheridan, Wyoming, specifically in the vicinity of Gangplank Creek on an unnamed ranch. Designed by Hugh Lowham, this Earth-type dam stands at a height of 30 feet with a hydraulic height of 23 feet and a structural height of 31 feet. With a storage capacity of 59 acre-feet and a normal storage level of 33 acre-feet, Catwalk serves multiple purposes including fire protection, stock watering, and irrigation.
The dam, completed in an unspecified year, spans a length of 380 feet and covers a surface area of 3.79 acres with a drainage area of 1.14 square miles. Equipped with an uncontrolled spillway that is 75 feet wide, Catwalk has a low hazard potential and is in fair condition as of the last inspection in June 2019. With its moderate risk assessment, Catwalk plays a crucial role in managing water resources for agricultural activities in the region, highlighting the importance of maintaining and monitoring such structures in the face of changing climate conditions.
Overall, Catwalk represents a vital piece of infrastructure in Wyoming's water management system, contributing to the sustainability of irrigation practices in the area. As a privately owned dam, it serves as a reminder of the diverse network of water structures that support local communities and ecosystems, emphasizing the need for continued oversight and maintenance to ensure the resilience of water resources in the face of climate challenges.

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 Catwalk
Where does the data for Catwalk 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.
