Dole Foods has completed repairs on a valve at Lake Wilson, allowing water levels to return to normal.

On Thursday, the water level at Lake Wilson, the largest freshwater reservoir in the state with a capacity of 3 billion gallons, was at more than 73 feet. The state Department of Land and Natural Resources said the normal operating level is 65 feet. 

At the beginning of this month, water levels dropped to 40 feet after the outlet valve became stuck, allowing water to drain from the reservoir. That raised concerns that the low water levels could endanger fish, including bass popular with anglers.

Tree roots and dumped shopping carts were visible along some areas of the exposed bank.

On April 8, Dole, operator of the reservoir, told the state that the butterfly valve was repaired.

The lake, also known as Wahiawa Reservoir, was replenished by the watershed in the west Koolau Mountains via the north and south forks of Kaukonahua Stream.
