Emergency water delivery aims to help birds, fish at Tule Lake
Water is headed to a critically dry wetland unit on Tule Lake National Wildlife Refuge to combat avian botulism, thanks to an arrangement forged between various agencies and stakeholders in the Klamath Basin. Sump 1B, currently the only wet unit on the refuge, began rapidly losing water primarily due to evaporation and minimal irrigation diversions last month. Irrigators and waterfowl biologists had filled it earlier this summer using water drained from the refuge’s larger Sump 1A, the bottom of which had likely never been exposed to air for millions of years.
