I have fished the Saline River in Saline, so I know there are carp here. I'm definitely going to be finding out. I'll let you know how it turns out.
The Saline River has a reputation for having a higher than typical concentration of mirror carp. Since the lake in Milan was formed from constructing a dam on the river, there is a pretty good chance that Ford Lake in Milan Nature Park has it's share of mirror carp as well.
If things progress according to plan, I may find out this weekend.
Interesting fact about Milan and the lake:
Part of its present City Hall is the former Ford Power Plant used for the Village industries. Henry Ford built the power plant in 1937 when he dredged Ford Lake. He also used a former lumber yard garage as a factory to make engine ignition coils. Ford intended his factory to depend upon hydraulic power, which is why he built a very fine dam to power his plant. However, the water power was inadequate, and his "Ford Industries" actually ran on steam engines depending on coal.
