Where can I get a copy of the official rules?  What about the tag list?

Printed copies of the official rules will be available at derby HQ at the start of the derby.  If digital copies are available before the derby, a link will be located here and on the derby Facebook page.  Ditto for the tag list!

Can I mail in my registration form and pay by check instead of purchasing my tickets online?

I paid.  Is my registration number the same as my order number like last year?

No. Each angler will have a unique registration number that will be provided to them on a registration card that must be picked up at derby headquarters (HQ) starting on March 31st.

Campgrounds and Launches

After opening weekend derby HQ will be at the Kern River Chamber of Commerce offices in Lake Isabella. Specific information about chamber hours and how to turn in tagged fish after opening weekend are contained in the Official Rules.

The hat design hasn't changed from last year, so will last year's purchase count towards the $10,000 tagged trout?

No. A hat or a t-shirt must be purchased this year for the fish to be at full value for opening weekend.

Can I pre-order a t-shirt or hat?

Hats and t-shirts will only be available at derby HQ.  

How much are the fish worth this year?

500 trout will be tagged ranging in value from $20 dollars to $10,000 for opening weekend.  See Official Rules for more info about tag values after opening weekend.

Boat Launches/Ramps are the responsibility of the Kern County Parks and Recs Department.

Campgrounds managed by RMRC are developed sites and fees for camping and day use apply.  Contact RMRC for a fee schedule.  Signs are posted at entrances to fee areas. 

Areas around the lake where no Fee signs are posted are undeveloped.  There are no camp hosts, fire pits, tables, or toilets in most of the undeveloped areas and, depending on the lake level, the lakeshore may not reach these areas.

Please contact the Kern River Valley Ranger District at (760) 376-3781  for information about undeveloped camping areas and for information about current fire restrictions.  Visit their website at this link for additional information.
