Summary

Constructed in 2006 by NRCS, this dam serves a primary purpose of "Other," with a normal storage capacity of 35 acre-feet and a maximum storage capacity of 55 acre-feet. The dam has a hydraulic height of 18.5 feet and a structural height of 22 feet, with a length of 325 feet and a surface area of 4.7 acres.

Despite being categorized as having a low hazard potential, Morris is considered to have a moderate risk level (3) based on a risk assessment. The dam has not been rated for its condition and was last inspected in March 2017 with an inspection frequency of 5 years. The spillway type of Morris is listed as "Uncontrolled," with no outlet gates or associated structures. The dam is not regulated by the state and has no state permitting or enforcement in place.

Enthusiasts of water resources and climate in the Morris area may find interest in the unique design and purpose of this privately owned dam, as well as its location along the Tribhatchie River. With a focus on risk management and maintenance, there is potential for further research and assessment to ensure the safety and functionality of Morris for the surrounding community and environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
