From the Starship Noise Assessment https://www.faa.gov/sites/faa.gov/files/2022-06/AppendixB_No..., it looks like you need maybe 20 miles distance for a tolerable level of noise (around 100 dB)
So I'm not sure regular launches from the lake will be tolerated by the lake shore's inhabitants. This is why Starship launch platforms should be 30km from shore (not 20km as I wrote previously)
