Summary
It was designed by USFWS and completed in 1995 for purposes of fire protection, stock, and as a small fish pond. The dam has a height of 9.8 feet and a length of 346 feet, with a storage capacity of 59.4 acre-feet and a surface area of 7.1 acres.
This dam, situated on the North Fork Grand-Tr river, is regulated by the North Dakota State Water Commission and has state jurisdiction, permitting, inspection, and enforcement. It has an uncontrolled spillway type with a width of 100 feet and one vertical lift outlet gate. The hazard potential of the dam is classified as low, and it has a moderate risk assessment rating of 3.
Although the condition of Steen Dam; Howard 1 is not rated, it has not been significantly modified since its construction. With its important functions for fire protection, stock, and as a small fish pond, this dam serves as a vital resource in the region while also contributing to the overall water management efforts in North Dakota.

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.
