Summary
This private dam is regulated by the North Dakota State Water Commission (NDSWC) and is subject to state permitting, inspection, and enforcement. The dam stands at 21 feet tall with a structural height of 24 feet and a length of 205 feet, offering a storage capacity of 69 acre-feet and covering a surface area of 5.3 acres.
With a spillway width of 100 feet and an uncontrolled spillway type, Schriock Fish Dam has a low hazard potential and is currently rated as not assessed for its condition. The dam sits on a stone core and soil foundation, serving the Pump Coulee water source. It is managed by a private entity and does not receive federal funding or oversight. Despite its moderate risk assessment rating, the dam has not had an Emergency Action Plan (EAP) prepared, posing challenges in emergency management and response.
Overall, Schriock Fish Dam plays a crucial role in water resource management in North Dakota, providing essential functions for fire protection, stock, and small fish pond purposes. Its moderate risk assessment highlights the need for improved emergency preparedness measures, while its low hazard potential and solid structural design underscore its importance in maintaining water security and environmental balance in the region.

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.
