Summary
This recreational dam stands at a height of 30 feet with a hydraulic height of 30 feet and a structural height of 40 feet. Completed in 1940, it serves multiple purposes including fire protection, stock, small fish pond, fish and wildlife pond, and of course, recreation. The dam has a normal storage capacity of 91 acre-feet and a maximum discharge of 272 cubic feet per second.
Despite being classified as having a low hazard potential, Gobbo #2 is in fair condition according to a 2016 assessment. The dam has slide and uncontrolled outlet gates, with a spillway width of 11 feet. It is regularly inspected every six years to ensure its safety and reliability. The surrounding area has a high risk assessment level of 2, emphasizing the importance of proper risk management measures and emergency preparedness in the event of any unforeseen circumstances.
Water resource and climate enthusiasts will appreciate the historical significance and engineering feats of Gobbo #2, as well as its vital role in providing recreational opportunities and supporting the local ecosystem. The dam's location in the picturesque town of Whitewater adds to its charm, making it a popular destination for outdoor enthusiasts and nature lovers alike. As climate change continues to impact water resources, understanding and maintaining structures like Gobbo #2 becomes increasingly important for ensuring water security and environmental sustainability in the region.

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.
