Summary
Pellatz. Located in Converse County along the Werner Draw river, this dam stands at 18 feet high and has a storage capacity of 113 acre-feet. With a surface area of 12 acres and a drainage area of 0.1 square miles, the dam serves a primary purpose of "Other" and is classified as having a significant hazard potential.
Despite being in fair condition as of the last inspection in June 2019, the Werner Ranch Site poses a high risk due to its location and design. With a spillway type of "None" and a single valve for outlet control, this dam is in need of regular inspections and maintenance to ensure its structural integrity and safety. The site is not under the jurisdiction of any federal agency but is regulated and permitted by the State of Wyoming through the State Engineer's Office.
Climate and water resource enthusiasts interested in the Werner Ranch Site can appreciate the unique challenges and importance of maintaining private dams in rural areas. With a risk assessment rating of "High (2)" and a designated inspection frequency of every 5 years, this dam serves as a reminder of the critical role of proper infrastructure management in safeguarding communities and ecosystems against the impacts of extreme weather events and changing climate conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
