SIERRA STREAMS

Watershed Monitoring, Research, & Restoration

California Naturalist Program


“The Sierra Streams California Naturalist program gave me the inspiration I needed to pursue higher education in a field that I am passionate about. The program has inadvertently had a big influence on the trajectory of my life…”


Sierra Streams Institute is delighted to be one of the training sites for the UC California Naturalist Program. In the program, you will become part of a committed corps of volunteer naturalists and citizen scientists, equipped with the skills needed to take an active role in local natural resource conservation, restoration, and education. The ten-week course combines science instruction with guest speakers, field trips, and project-based learning to explore the unique ecology and natural history of the northern Sierra foothills.

Advanced Training – Stream Ecology Fall 2026!

Advanced Ecology Training: Brought to you by SSI in collaboration with California Naturalist 

Sierra Streams Institute is bringing back our Stream Ecology advanced training, and this year we’re diving even deeper. No prerequisites needed — just curiosity and a willingness to get your feet wet.

Learn how stream geomorphologists and biologists actually read our waterways, and get hands-on with the same tools scientists use in the field.

Taught in two distinct sections the course provides background knowledge and field protocols skills to launch you into the world of stream science. Join us for interactive lectures and enriching field experiences. Lecture and field days are paired into sections by topic. Each section costs $75 and if you sign up for both the fee is $125, a $25 savings!

Part 1 – Physical and Chemical Science of Streams

This section will build a robust understanding of watersheds that includes how rivers are classified and how watersheds are composed of sub-watersheds that all have unique physical and chemical contributions to the main stem streams. Stream flow and geomorphology will be covered in this section to build an understanding of the geologic basis for creating the common morphological features of the stream (think pools and riffles!) and how those form the basis for stream habitats. Lastly the section will review water quality parameters that we monitor in order to determine stream health and we will look to debunk a number of water quality myths! So bring you myths ready to share. In the field participants will learn how to collect flow data and how to collect a suite of water quality data including dissolved oxygen, electrical conductivity, turbidity, pH and more.

Part 2 – Biology of Streams and Nutrient Spiraling

Part 2 will cover some of the seminal concepts around the flow of energy in river systems and how nutrient movement, uptake, and cycling result in the plant and animal communities we see across a given watershed. Concepts will include the River Continuum Concept, Flood-Pulse Concept, the Intermediate Disturbance Hypothesis and more! In the field participants will  learn to collect physical habitat data and will collect and identify benthic macroinvertebrates living in our streams.

Two parts:

  • Physical Properties of Streams — channel geometry, flow, and water quality
    • October 21, 2026 – Presentation
    • October 24, 2026 – Field Day
  • Biology of Streams — the aquatic insects and fish that call our streams home
    • October 28, 2026 – Presentation
    • October 31, 2026 – Field Day

Back Up Dates (in case of weather) – Early November

Evening presentations build your conceptual toolkit. Field days put it into action.

You’ll leave with a real understanding of the issues facing our local streams and rivers — and how they connect to challenges playing out across the state.

Details and registration coming soon. If you are interested in participating, fill out this interest form.

Frequently Asked Questions About Advances Stream Ecology Training

Where Does the Course Take Place?

The course will be held at the Sierra Streams Institute office for the presentation evenings at 117 New Mohawk Road Suite H in Nevada City.

The field days will take place at select field locations but are still TBD. Last year the first field location was Pioneer Park in Nevada City and the second one was the Discovery Trail on the Bear River off of Bowman Road. There is a good chance we will use the same locations this year.

Are You Inviting Any Tribal Partners To This Workshop?

Currently we do not have Tribal Partners attending the training. However, this is a great idea and we hope to in the future!

Will Participants That Complete the Advanced Training Stream Ecology Course Receive A California Naturalist Certificate?

No, you will not receive the California Naturalist Certificate for this course. This course is an “Advanced Training” and is much shorter and less involved (2 presentations and 2 field days) than the standard course. The standard course, which we will run in the spring (March through May), requires 40+ hours of instruction and field work. Please let us know if you are interested in the standard course in the spring.

Is the Course Appropriate for Grad Students?

That depends. If a grad student is studying the hydrology and biology of streams then this course might not provide a ton of extra insight or understanding to their current studies. However, our course is still broad and covers water quality, geomorphology, and biology of streams. So this is a well rounded refresher for grad students in the field and definitely for grad students studying other fields.
