Water assets associated with a property along Mill Creek, a tributary of the Sacramento River in Tehama County, CA, have been historically used to irrigate fields and for stockwatering for over 90 years. The Nature Conservancy has purchased the property and associated water right with an aim to augment flows and improve ecological function and resilience in this critical watershed, supporting threatened Spring-run Chinook salmon. The water sustainability action being implemented with the Mill Creek Nobmann Right involves ceasing diversion of water and forgoing irrigation keeping over 1,200 acre-feet of water in stream over the course of the year.
