In KY the COE had suspended launch fee collection until tomorrow ... owing to the Corona Virus & the resulting "rules of conduct/gatherings". Not all lakes under the jurisdiction of the COE only have "pay to use" launching facilities, but those other facilities are not maintained by the COE, either.

I'd suggest calling the regional office of the lake(s) in question and ask if the launch use fees have been removed for the rest of the year, or not.
