Foster-Ahrends Lake offers some trout fishing. Shore or from a kayak, they can be taken. Spinners and/or count-down rapalas in #3 to #7. Rainbow trout or gold/orange are good starting colors for the raps.
When you get the kayak Cesterwoods will offer some nice bass casting during the week, weekends will be hectic.
The Zumbro River below the Power Dam on Lake Zumbro, north of town, has some outstanding smallie fishing for a kayaker. Beware of mega-muskies there as they they share the water with the smallies. Closer to home here the Zumbro River just south of the 37th Street Bridge, east of the north Hy-Vee will give up a variety of fish at times. Personally I like this stretch more for early spring and late fall….smallies and walleyes maybe keep you entertained.
Lake City on the shores of Lake Pepin has a lot of shoreline that is fishable and you never know what might grace your offering. Between Wabasha and Minnieska to the south on the Minnesota shoreline you’ll find a wide-spread system of backwaters adaptable to either shore or kayak fishing.
Personally I’d look to the Mississippi at this time of year. Either rip-rap shoreline or backwaters will offer up more fish than anything locally for a while now. The Zum below the power dam stretch will be ok now too but the ski’s maybe won’t be as easy to find until the water cools in the fall. I’d really be putting my time in around Lake City at the peir or the break water in front of the sailboat harbor.
