Summary
The dam serves the primary purpose of irrigation and is classified as an Earth dam with a Stone core and Rock foundation. Standing at a height of 39 feet with a hydraulic height of 33 feet and a structural height of 41 feet, the dam spans a length of 1025 feet, holding a storage capacity of 437 acre-feet.
With a significant hazard potential and an unsatisfactory condition assessment as of April 2020, Iowa Creek Dam is in need of attention and maintenance to ensure its structural integrity and safety. The dam features an uncontrolled spillway with a width of 10 feet and two slide (sluice gate) outlet gates. The risk assessment for the dam is moderate, with a hazard rating of 3.
Despite being privately owned, Iowa Creek Dam falls under the jurisdiction of the Nevada Department of Water Resources for regulation, permitting, inspection, and enforcement. The dam has been modified in 1970 for structural improvements, and regular inspections are conducted every three years to monitor its condition. As a crucial component for irrigation in the area, the preservation and maintenance of Iowa Creek Dam are essential for water resource and climate enthusiasts to monitor and support.

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.
