Found at Flightsim yesterday, and with the Avia amphib very much in mind, this is well worth having. Its Forggensee in Bavaria and comes in 2 parts;
forggensee-v2_fs2004_part_1.zip
forggensee-v2_fs2004_part_2.zip
Plenty of AI activity, both surface and air and I suggest a familiarisation trip in Bill Lyons Gar Wood Cruiser.
