Summary
Completed in 1956, Marlatt stands at a height of 9 feet and has a storage capacity of 200 acre-feet. The dam stretches 600 feet in length and covers a surface area of 19 acres, serving as a vital water resource for the surrounding area.
Despite being classified as having a low hazard potential, Marlatt has been assessed to be in fair condition as of the last inspection in June 2017. The dam features an uncontrolled spillway with a width of 40 feet and is equipped with a single valve outlet gate. With a moderate risk assessment rating of 3, Marlatt is subject to regular inspections every 5 years to ensure its structural integrity and safety.
Located near the Marlatt Spring in MORRILL, NEBRASKA, Marlatt plays a crucial role in irrigation and water management in the region. With its strategic positioning and efficient design, Marlatt continues to be a key asset in maintaining water resources and adapting to climate challenges in the area.

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.
