2026 announcements

Idaho state records IDFG announced in 2026

IDFG keeps two record lists: certified weight, for fish weighed on a certified scale, and catch-and-release, for fish measured by total length and let go. The full lists live at idfg.idaho.gov/fish/record, which could not be opened during the November 2026 site maintenance.

So this page lists only the records IDFG announced in 2026 that could be read from its dated releases or from news reports citing IDFG: 7 in all. Angler names are not shown. A TV report in October 2026 said 17 catch-and-release records had fallen that year, so this list is short.

What is the newest Idaho rainbow trout record?

20.03 pounds from Dworshak Reservoir, announced by IDFG in January 2026.

A record by total length for a fish released alive; IDFG keeps it apart from the certified-weight list.

How much must a new record beat the old one?

Catch-and-release records must be beaten by at least half an inch, or 2 inches for white sturgeon; within a quarter inch is a tie, per the IDFG rules.

Why does this list leave off who caught each fish?

This site leaves them off; the IDFG releases linked in each row carry the full story.
