Project Goal:

Protect CA’s largest spring-fed river, over 30 miles of wild and native trout habitat, and one million acre-feet per year of cold, clean volcanic source water that provides habitat for native fish and wildlife, water for hydropower and agriculture, and reserve storage and recharge for Shasta Reservoir.


Over 2600 fish tagged since April 2013

Project Description

Since 2013, team members from CalTrout, UC Davis Center for Watershed Sciences and Fall River Conservancy, have collected and tagged 3,354 fish with Passive integrated Transponders (PIT). The PIT tags track fish movement, allowing us to monitor population trends and life history patterns to identify key habitat areas for protection. Fish tagging occurs twice a year, once after fishing seasons ends in November and again before it begins in April. Researchers also collected small samples of genetic data from fins. The genetic analysis has revealed that there are genetically-different sub-populations of rainbow trout in the Fall River. These sub-populations encounter each other in the main Fall River system but are segregated in spawning locations with very little gene flow between populations. This program illustrates how CalTrout uses partnership, technology, and innovative science to improve fisheries management.
