After 9/30, the river is only open to fishing from Hwy 2 downstream (north). Most guys concentrate on the area just north of 2, but people will be fishing in most areas between 2 and the lake.
Public access is easy. Much if not most of the shoreline is public in that stretch, and the private areas are normally well posted and many have signs posted welcoming foot traffic (provided it is along the river and not on their porch).
Spoons and spinners will work. Don’t pass up spawn, or even a crawler. I’ve seen lots of fish taken on a crawler bouncing on the bottom at the tail end of a riffle. Lots of fly guys up there too (myself included), egg-sucking leeches and two-egg patterns are the standards.
Kings are very limited in the Brule. Cohos are available in the sizes you are thinking about.
Shore casting at the mouth is an option too. Access is easy. Lots of space to move about. Real sandy at the mouth, easy wading.
A few notes: it has been very dry up north this year, delaying many of the runs. The lake run browns are trickling in. Fishing has been slow of late becuuse of the lack of rain to bring fresh fish in. The Brule got some rain at the end of this week which pushed the flow up and raised the river level a bit. In the absence of more rain, things should be getting back to normal by the time you are there.
Also, and you may already know this, expect to see a lot of people. Your midweek trip will help a bit, but given the lateness of the runs, guys may be focusing their efforts (fishing days) a little more than normal. Finally, the Brule River Sportsmens Club has a fantastic map that is for sale in the area (check the gas station right on 2 in the town of Brule, that’s where I got mine). The map shows the river in detail, including the names of holes and runs that lots of guys like to fish. Pick up a map, read some of the posts on the Brule River Sportsmens Club webpage, and have fun. Let us know how you did.
