Lake Ontario smallmouth bass fishing is slowly bouncing back from what it was back in the late 1990s and early 2000s. The bass have not produced a strong year class of fish in well over a decade and it's a mystery to biologists. We did have some terrific smallmouth fishing in and around Oswego over the past three years. Fishing is still strong north of Henderson Harbor and around Chaumont, but that's out of my "wheelhouse" for guiding. Friends did well up there in 2018.
Early season nearshore brown trout fishing can be excellent, with fly-fishing a strong option. These fish run from 2 to 5lbs on average, though there are always opportunities for some much bigger fish - fish over 10lbs. As browns move offshore, jigging is usually a good option. Lake Ontario brown trout fishing was pretty dismal for us in 2016, likely due to poor survival of young stocked fish after the brutal winters of 2014/15.
Kings, lakers and rainbows can be jigged out here when the conditions are right. It's spotty and not something I guide for, but it's a worthy challenge. I haven't jigged up a coho or Atlantic out here yet, but there's no reason why they wouldn't hit. It's just a matter of time.
Drum also are abundant around Oswego and throughout much of Lake Ontario. If I get time, I'll be working on fly-fishing opportunities here. There are some nice flats and sight-fishing drum is a good possibility.
In terms of guiding here, I'm available for smallmouth bass. We had a great trip here in 2018. We encountered plenty of beautifu smallmouth bass plus some gar,a brown trout and a walleye - now THAT'S what I call "mixed bag fishing!" The extra drivetime and parking charges here at Oswego (or Sodus et. al) will necessitate a surcharge.
