Not enough to support a car. Just ask the guy on the WBAY website.
While the vast majority of the "cars" south and east of the bridge are for the golf course there are people who fish along Punoqua from shore for walleye and perch in the spring and cats during the summer. The google maps app actually shows 4 boats, err I mean cars, in the last fishable spot before the golf course. "Boats" that are northwest and west of the main gap I'll assume (visualize in my mind) you mean are ones fishing Sunset (northside) and Oakwood (southside) points and are usually fishing walleye and perch but you never really know what you will pull up. Could be sheeps, cats, gills, etc. etc. Tight lines.

Was a couple of four wheelers out still, although I would not recommend that. With these temperatures, not many days left of walkable ice.
