Summary
Designed by USDA NRCS, this Earth-type dam serves the primary purpose of debris control along Mission Creek-TR. With a height of 19 feet and a length of 552 feet, the dam has a storage capacity of 60 acre-feet and a drainage area of 1.65 square miles.
Despite its low hazard potential, Brown & Brown CO Scd Gsd No 57 has a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 60 feet and no outlet gates. While the condition assessment is listed as "Not Rated," the dam's emergency action plan status, inspection frequency, and risk management measures remain unspecified. However, the structure has not undergone any modifications since its completion, and there have been no reported incidents or inspections in recent years.
Water resource and climate enthusiasts may find interest in the unique features and historical significance of Brown & Brown CO Scd Gsd No 57. Its location in the Rock Island District and association with the Natural Resources Conservation Service add to the overall importance of this debris control dam. Further research and monitoring may be necessary to ensure the continued safety and effectiveness of this structure in managing water resources in the area.

Dam Data Reference
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.
