I took my hydrophones (underwater microphones) down to the pier last night and recorded in a few places where the water was deep enough. I've heard the lake is quite high at the moment which is good for my purposes. Not so great for the livestock with less of the banks to graze on. Serendipitously a motorboat was coming in to dock, breaking up the eeriness with a loud crank as it came to a stop.
Part Five: Various alarms reversed and pitched down, with layers of hydophone recordings (a little delay on one) from under the water at the pier in Lake Chapala (with bonus motor boat).
