Haven't been to the Jacobson Park lake in some time, so I don't know about the general populace being all that into the social distancing thing out there. But I'm sure a bucket of wax worms would provide lots of action from small Bluegills, Catfish, and possibly even Carp. It's a FIN's lake so you'd best get there fairly early if you want a decent bank spot or on one of the two walkway piers.

There's also the Southland Christian Church "lake", just over the Jessamine Co. line on Harrodsburg Rd. ... but it's pretty small and can get crowded pretty quick. It's also a FIN's lake.

The Horse Park lakes are also FIN's lakes, but I believe they charge for entry into the park.

There's Lake Reba in Richmond, that has bank access areas.

I'm pretty sure that most of the playground areas are closed at any lake mentioned, on account of the Covid-19 virus.
