The Little Susitna is a Cook Inlet salmon stream near Houston and Wasilla, and its regulations divide the river at the Parks Highway. Typical runs include king, coho and sockeye salmon, but timing does not establish permission to fish. ADF&G’s 2026 documents close king salmon fishing, including directed catch-and-release, and prohibit retention of coho 16 inches or longer beginning August 19 under an emergency order.
Where the river sits in the regulations
The Little Susitna flows to Cook Inlet. Find its rules in ADF&G’s Knik Arm regulations booklet; nearby Susitna drainage rules are not a substitute. Read the river entry alongside the general regulations and applicable emergency orders.
ADF&G’s 2026 Knik Arm booklet lists the river from its mouth to the Parks Highway as open year-round to species other than king salmon, subject to restrictions. Upstream of the Parks Highway, it closes all salmon fishing year-round. Verify with ADF&G through its sport fishing regulations page before choosing a fishing location.
A highway crossing does not establish public access across adjoining land. Confirm permission to reach the bank, parking arrangements and any launch restrictions separately. Treat the regulatory boundary and permission to enter property as separate questions.
Runs and typical timing
ADF&G’s run-timing sheet, dated April 2022, gives these typical Little Susitna windows. They describe seasonal patterns, not a forecast or an open fishing season.
- King salmon: lower river May through late June; upper river mid-June through mid-July.
- Coho salmon: lower river mid-July through mid-August; upper river early August through early September.
- Sockeye salmon: mid-July through early August.
Those windows come from ADF&G’s April 2022 sheet. Its “upper river” timing does not override the salmon-fishing boundary at the Parks Highway. The monthly salmon timing guide puts these runs alongside other Mat-Su waters.
Fish can be present during a closure. Plan around both the likely run and the rules for the intended species, then adjust for water conditions and safe access.
King salmon restrictions in 2026
Emergency Order 2-KS-2-11-26, issued February 9, 2026, closed king salmon fishing from Cook Inlet to the Parks Highway Bridge from May 1 through July 13, 2026. Catch-and-release fishing for kings was also closed. During that period, the order allowed only one unbaited, single-hook artificial lure with a hook gap of one-half inch or less.
Under that same 2026 order, an incidentally caught king had to be released immediately without being removed from the water. ADF&G’s April 22, 2026 announcement, Emergency Order 2-F-H-04-26, subsequently stated that all directed sport and commercial wild king salmon fisheries in Northern Cook Inlet were closed for the 2026 season. The Knik Arm booklet also identifies king fishing as closed by emergency order in 2026.
The concern is spawning escapement: salmon reaching the river’s spawning population. ADF&G’s February 2026 order gives the Little Susitna king sustainable escapement goal as 2,100 to 4,300 fish counted at the weir. It reports low runs from 2022 through 2025; the goal was reached in 2022 after a mid-season sport closure, but missed in 2023 despite a mid-season closure and in 2024 and 2025 despite full-season closures.
Verify with ADF&G on its emergency orders page before fishing. Historical king timing is not authorization to target kings.
Coho restrictions and the booklet comparison
Emergency Order 2-SS-2-48-26, issued August 17, 2026, prohibited retaining or possessing Little Susitna coho 16 inches or longer from August 19 through December 31, 2026, unless superseded. Those fish had to be released immediately without leaving the water. The order also restricted fishing from the mouth to the Parks Highway to unbaited artificial lures from August 19 through September 30, 2026.
ADF&G’s August 2026 order reported 1,385 coho past the weir as of August 17 and projected escapement of 2,104, against a sustainable escapement goal of 9,200 to 17,700. It superseded Emergency Order 2-SS-2-43-26, which had reduced the coho bag to one beginning August 6, 2026.
| Rule | What the 2026 booklet says | What changed by 2026 emergency order |
|---|---|---|
| King fishing | The Knik Arm booklet identifies king fishing as closed by emergency order. | Order 2-KS-2-11-26 explicitly closed targeting and catch-and-release during its effective period; the later Northern Cook Inlet announcement established the season closure. |
| Coho handling | A coho removed from the water must be retained. | Order 2-SS-2-48-26 prohibited retention and possession of covered coho and required release in the water. |
| Bait | Bait and multiple hooks are allowed August 6 through September 30. | Order 2-SS-2-48-26 required unbaited artificial lures August 19 through September 30. |
| Gear before August 6 | Only unbaited artificial lures or flies October 1 through August 5. | Order 2-KS-2-11-26 added the single-hook and hook-gap restrictions during its effective period. |
The comparison uses ADF&G’s 2026 Knik Arm booklet and the named 2026 orders. Verify with ADF&G on the emergency orders page; emergency orders can change anything in the regulations booklet at short notice. The emergency-order guide explains how to read overlapping restrictions.
Standing rules and a departure checklist
ADF&G’s 2026 Knik Arm booklet limits fishing to 6 a.m. through 11 p.m. from May 15 through July 13. It also prohibits fishing from a motorboat unless its motor is a four-stroke or direct-fuel-injection two-stroke; other two-strokes may transport anglers to bank-fishing locations, but fishing from those boats is prohibited.
Under that booklet, after retaining a bag limit of chum, coho, pink and sockeye salmon 16 inches or longer from the Little Susitna, an angler may not fish for any species in the river that day. Verify with ADF&G’s regulations and emergency orders pages. Read the bag-limit and gear explanation before deciding what to retain.
- Confirm the intended bank or boat location is within legal salmon waters.
- Read the Little Susitna booklet entry and every applicable emergency order.
- Check order effective dates, species, boundaries and gear restrictions.
- Confirm access permission, launch arrangements and motor eligibility.
- Prepare to identify and release restricted fish while keeping them submerged.
- Read weir updates with their reporting date and any counting limitations.
Frequently Asked Questions
Does a weir count show how many fish are available to catch?
A weir count records passage at the counting location, not fish available at every fishing spot. A partial count and a projected escapement are different measures; read the date and explanation accompanying each.
Can kings be targeted if they will all be released?
No, under ADF&G’s 2026 king closure. Emergency Order 2-KS-2-11-26 explicitly included catch-and-release fishing; verify with ADF&G’s emergency orders page before any future trip.
Did the coho order close every kind of fishing?
Emergency Order 2-SS-2-48-26 prohibited retention and possession of coho 16 inches or longer and imposed a seasonal bait restriction. It did not itself close all fishing; verify applicable species and gear rules with ADF&G’s emergency orders page.
Can this page establish what is legal on a later visit?
No. This guide explains dated documents and is not legal advice. Verify with ADF&G’s sport fishing regulations and emergency orders pages because emergency orders can change anything in the booklet at short notice.
