Completed in 1977, this earth dam stands at 112 feet high and has a storage capacity of 15,600 acre-feet, serving a drainage area of 43.4 square miles. Despite its importance for irrigation, the dam is categorized as having a high hazard potential and poor condition assessment, with a risk level of moderate (3).
The dam's spillway, which is uncontrolled, has a width of 65 feet and a maximum discharge capacity of 4,260 cubic feet per second. The last inspection conducted in June 2021 revealed the need for improvements, highlighting the urgency for maintenance and risk management measures. With the primary purpose of irrigation, Newlan Creek Dam plays a crucial role in water resource management in the region, but its deteriorating condition underscores the importance of ongoing monitoring and maintenance to ensure the safety and sustainability of the structure for both agricultural and environmental purposes.
