“Year after year we get amazing volunteers who make an incredible difference in what our program is able to achieve. Not everyone comes in with the same skill sets or abilities, but most everyone comes in with a positive attitude and a genuine interest in contributing to the river ecosystem and that’s what it’s really all about.”

– Heidi Ann Isner, KRCD Environmental Programs Manager

Volunteer Opportunity – Trout Incubator Building (Currently recruiting for Round 3 of the 2019-2020 season)


For over a decade, the Kings River Fisheries Management Program has seasonally (November-April) incubated rainbow trout fry for release in the lower Kings River. In 2012, the program was able to move operations from cement boxes along the river’s edge to a small incubator building below Pine Flat Dam. The building is equipped with two 15′ long rearing tables that accommodate two raceways apiece. The program charges the building with 100,000-150,000 rainbow trout eggs, up to three times annually. Once the eggs hatch, the trout fry rear for approximately six weeks before release.

Annually trout are incubated, reared, and released in three rounds: Round 1 (November-December), Round 2 (January-February), and Round 3 (March-April).

Ongoing Volunteer Opportunity – February 29 – April 19

Volunteers needed on weekends and whenever our staff is unable to attend to the trout incubator building. Most volunteers will spend one hour or less at the incubator at a time of their choosing. These volunteers will be required to go through a brief orientation and be issued a key so they may access the facility when they volunteer.

During trout rearing the program relies on ongoing volunteers to help:

  • clean raceways
  • monitor trout eggs and fry
  • record water temperatures and flow
  • feed trout fry

Generally, only one or two volunteers are required per day.

Single-Day Volunteer Opportunity – April 22

Once trout fry are ready for release (approximately 1″-1.5″ long) we rely on volunteers to help us stock them into the river between the Army Corps of Engineers Bridge and Avocado Lake Park. Fry release is scheduled for April 22, 2020 from 3:00-6:00 pm. Volunteers should be able to transport 2-3 five-gallon buckets of trout fry in unheated personal vehicles (trucks preferable) and should be able to carry a 20-pound bucket over uneven terrain. Volunteers for this day meet at the incubator facility.

Generally, up to ten volunteers are required on this day.


This is an excellent opportunity to take part in the trout lifecycle. Scheduling is flexible (especially for students) and the trout incubator sits adjacent to a scenic walking trail and Put & Take fishing access on the Kings River.

No experience necessary.

Contact Lori Werner (KRCD Environmental Resources Analyst) for scheduling and additional information.
