Seasonal Fishing by Species
Spring (March-May): Steelhead and Trout Tactics
In Spring, fish in the Ausable River come to life and steelhead trout migrate upstream with their silver scales flashing in the sun through the rushing water.
Fly fishing with nymphs and streamers in areas where the current creates natural food paths for fish is the ticket to success. These areas, both shallow and deep, are rich in oxygen and food sources, and attract species like trout and steelhead, which are driven upstream by their spawning instincts.
Brook trout also become more active, feeding aggressively in preparation for later season spawning. Spin fishing with small spinners lurers or worms is highly effective. Using light spinning rod and reel combos suitable for the streams and tributaries frequented by brook trout, anglers can cast near overhanging branches or weed beds where the water is warmed by the sun, possibly catching sight of a vibrantly marked brook trout as it rises.”
Summer (June-August): Smallmouth Bass and Trout:
While the Ausable River is predominantly a trout river, sections may offer opportunities for smallmouth bass fishing, with these fish known for their energetic fights.
Kayak fishing can be enjoyable in the lower, calmer sections of the river, using techniques suited to the river’s flow and depth. In these areas, fishermen can explore using swimbaits and jerkbaits, especially targeting bass.
In the upper Ausable, anglers will find optimal conditions for fly and spin fishing from the banks or while wading. This section, characterized by shallow depth, fast current, and a rocky bottom, is ideal for trout fishing.
Brown trout, which prefer cooler waters, are more likely to be found in deeper pools during the hot summer days. Early mornings and evenings are the best times for fishing, using nymphs and streamers that mimic natural prey. Casting into deeper, high-current areas where brown trout are likely to seek refuge can increase the chances of a successful catch.
Fall (September-November): Salmon and Steelhead
During autumn, the Ausable River becomes a prime location for anglers. This season is known for the arrival of salmon in October and November. Salmon, identifiable by their distinct coloration, are a primary target for fishermen during their runs, particularly around the river mouths.
Drift fishing with spawn bags or spoon lures is a favored technique during this time, effectively attracting salmon in areas where they tend to gather. It’s important for anglers to be aware of and adhere to fishing regulations, as salmon fishing can be subject to specific rules regarding size and season.
In addition to salmon, steelhead trout also make their way upstream in the fall. This season is a peak time for fly fishing.
Brown trout and walleye are also active in the river during fall. Brown trout are typically found in the river’s deeper sections, where they can be caught using nymphs and streamers, particularly in the cooler times of day.
Although the Ausable is not well known for walleye fishing, they are found in deeper, slower-moving areas of the river and are responsive to jigs and lures that mimic minnows, especially during twilight. Try your luck in areas that offer suitable spawning grounds, such as gravel or sandy bottoms for laying eggs.
Winter (December-February) Ice Fishing: Targeting Brown Trout
Ice Fishing on the Ausable River offers several opportunities particularly for brown trout. Browns often reside in the river’s deeper pools during the colder months. Effective fishing techniques include jigging with small jigs baited with wax worms or minnows.
Before heading out for ice fishing, it’s essential to verify ice safety, considering the river’s varying conditions. Ensure the ice is adequately thick and stable, and always have safety gear like ice picks and a life jacket on hand.
