Mt Shasta CA, Big Spring Ranch Bill Chesney from the CA Dept of Fish & Game counting redds in a stretch of river that is heavily grazed by cattle who have full access to the river and often drink and eat in it. Mt Shasta in the background. The Shasta River runs through Big Springs Ranch about 20 miles north of the town of Mt Shasta. The ranch, which is contributing to degraded habitat conditions, and actually warming water temps by upwards of 10 degrees as the river passes through the ranch and then spills into the Klameth, is currently under contract for purchase by TNC. Since the contract began, TNC and partner organizations have been allowed to research this stretch of river for the first time. They have discovered that is it a very fertile juvenile rearing area and that there are a surprising number of returning salmon in spite of habitat degradation by grazing cattle (often in the river) and irrigation practices. If this purchase is successful, TNC has the chance to improve a large stretch of habitat and quickly improve conditions that will effect numbers of returning fish and habitat in the Shasta and Klameth Rivers. The Shasta River and its tributaries create one of the most important spawning nurseries for Chinook salmon in the entire Klamath Basin.
