Water flowing into California’s Tule Lake NWR Sump 1B

Tule Lake NWR

Water is flowing into Sump 1B on Tule Lake National Wildlife Refuge following the recommendation from U.S. Fish and Wildlife Service to the Bureau of Reclamation earlier this month.

Water levels in the approximately 3,000-acre wetland unit have begun to rise, and waterfowl and waterbird usage is starting to increase. Molting ducks are finishing their molt and migrants are starting to arrive, with little to no signs of botulism this season.

In the adjacent Sump 1A, drawn-down in an attempt to mitigate a botulism outbreak, a sea of smartweed and goosefoot is beginning to take off.
