Rain raised Lake Wilson a foot Thursday and Friday, helping to stabilize water levels that were dropping a week ago.

The reservoir levels rose to 57.7 from 56.7 feet near the Wahiawa spillway in about a day, said Carty Chang, chief engineer for the state Department of Land and Natural Resources.

Water levels are usually between 70 and 80 feet, according to the state.

Operator Dole Foods Co. of Hawaii said it had managed to close a once-stuck outlet valve a little more, also aiding in the stabilization of water levels. Dole managed to shut the outlet valve by two-thirds on Monday. Company Operations Director Daniel Nellis said yesterday the situation was stabilized.
