Summary
This private-owned Earth dam stands at a height of 20 feet and spans 600 feet in length, with a storage capacity of 152 acre-feet. Situated on Cajka Branch, the dam has a hydraulic height of 20 feet and offers a surface area of 9 acres.
Despite lacking a spillway, Matejka Lake Dam is equipped with one outlet gate. The dam's hazard potential is labeled as "Not Available," with a high risk assessment rating of 2. Although the condition assessment is listed as "Not Rated," the dam undergoes regular state inspections and permitting. Furthermore, it is interesting to note that the dam is not under federal jurisdiction and is not regulated by the state.
For water resource and climate enthusiasts, Matejka Lake Dam provides a fascinating case study of a privately-owned structure that serves multiple purposes while facing a high risk assessment. The dam's location, design, and history offer valuable insights into the management and maintenance of smaller-scale water storage facilities. Additionally, the absence of certain regulatory measures raises questions about the oversight and safety of similar dams 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.
