Summary
Completed in 1966, Pratt serves a primary purpose of "Other" and has a maximum storage capacity of 192 acre-feet. The dam stands at a height of 18 feet and spans 500 feet in length, with a spillway width of 150 feet. Despite its low hazard potential, Pratt is not currently rated for its condition and has not undergone recent inspections or assessments.
Situated on TR-Police Creek, Pratt plays a vital role in managing water resources in the region, with a drainage area of 2 square miles. The dam's construction was funded and designed by the Natural Resources Conservation Service, and it is subject to state jurisdiction, permitting, inspection, and enforcement. With its strategic location in Congressional District 00, Montana, Pratt stands as a testament to the collaborative efforts between federal and state agencies in safeguarding water resources and infrastructure in the area.
Water resource and climate enthusiasts will appreciate the unique characteristics of Pratt, from its historical significance to its operational challenges. While the dam's condition remains unrated and its hazard potential is low, the absence of recent inspections and assessments raises questions about its long-term sustainability. As stakeholders continue to monitor and manage the dam's performance, Pratt serves as a reminder of the importance of proactive maintenance and risk management in ensuring the resilience of water infrastructure in the face of changing climatic conditions.

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.
