Lower Klamath National Wildlife Refuge

Water flows into Lower Klamath National Wildlife Refuge through the Ady Canal on Friday.

After a summer spent drying up, Lower Klamath National Wildlife Refuge finally began receiving a measurable flow of water, thanks to the start of the winter irrigation season on December 1. The refuge can receive up to 11,000 acre-feet of water between December and February depending on how Upper Klamath Lake is filling.

Water began flowing into the refuge's Unit 2 wetland through the Ady Canal on Wednesday and was flowing at around 60 cubic feet per second at 5 p.m. Friday. It was the only significant inflow to the refuge since last winter other than roughly 750 acre-feet transferred from the Wood River Valley by the California Waterfowl Association in September.
