Welcome to IDA B.P.!
You have a very valid point on the city lakes not being busy… year around. Yes, you can get quite a few shore fishermen here and there, the docks will get pretty crowded on occasion, at the same time most of the shoreline will be void of fishing people. Boat traffic is limited to trolling motor only, and there is an average of 3 or 4 boats on the lake in a given day in a weekend.
No cabin cruisers, no jet skis, no snowmobile and atv traffic to fly by your house at 80 mph in the middle of the night in a convoy. The only real hazard is the sailboaters in which some are not too good about keeping their distance some days. If we stop and look at it that way, the inner city lakes are peaceful in comparison to other lakes around the state.
The only frustrating factor fishing the city lakes with a boat is probably finding a parking spot, you might end up walking a block(big deal).
