Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout, salmon & steelhead.
On the ADF&G Southeast sport fishing regulations, Petersburg & Wrangell: catch-and-release for rainbow/steelhead or cutthroat trout, Arctic char/Dolly Varden, lake trout or Arctic grayling list (Alaska Department of Fish and Game, Division of Sport Fish, read 2026-10-23).

Measured from the National Hydrography Dataset (large scale) (U.S. Geological Survey, read 2026-11-04) for this water’s own mapped feature. Rounded figures; they describe the channel, not today’s conditions.
Listings marked Unclaimed are built from open map records and the business's own website: confirm licensing, rates, dates and hours directly.

Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.
At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.

Not a statement of access, fish presence or conditions.
A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.
Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown. Regulations, stocking, species and season statements link to the agency that publishes them; this page copies only the species names and the quoted sentences. Guide and shop listings come from the Legendary directories. Position: a point on the mapped channel of “Castle River” near the middle of its length in Alaska, from the USGS National Hydrography Dataset, read 4 Nov 2026. It marks the water, not a particular access or reach. Water type is our own classification.
