Adult Support Needed?: No
Steelhead trout are one of the native fish species that calls the San Lorenzo River home. They have a very unique life cycle. Steelhead trout are born and grow up in the river. When they become adults, steelhead trout migrate to the ocean, where they spend up to three years feeding on rich ocean food and growing bigger. Steelhead trout eventually return to the San Lorenzo River to spawn (lay eggs), beginning the cycle anew. In this activity, you will:
- Observe the unique life cycle of steelhead trout in YouTube videos
- Read text to become experts on one life stage
- Create a poster sharing what you learned about your life stage with your class, friends or family.

To all of the Watershed Rangers students, teachers and program partners, although we will not be able to see you in classrooms, field trips and after school programs right now, we hope to provide you and your loved ones with online resources and activities during this time.
