Research direction
Start by reading the AI city-production logic that decides whether a city should build naval units, then check how it distinguishes a usable water body from a coast or small lake. The issue names no files or tests, so locate the relevant entry point and existing AI tests first. Done means a city next to a small, unusable lake no longer chooses a navy; the issue also raises, but does not define, making the lake-size threshold configurable.
Written by the indexing model from the issue text.
Description
In Civ, there's a minimum size, I think it's 21, for lakes to support navies. This should probably be configurable, as sometimes it would be nice to do a stealth invasion across a small lake.
But right now, the C7 AI just looks at the presence of a coast:

That navy is never going to be useful; Croton should be building something else.
Marking as a bug but also as low-priority since this is a rare and not super consequential occurrence. You can still fix it if you want though.
