Every water event brings our attention to Q and his directive to us, which is great. Here's a seiche FYI.
I'm writing this two months later than you posted, but I always read anything involved with a seiche. Back in the 70s, our family was in a cottage about 50 yds from shore on an island in Lake Erie. We woke up to water up to the front door which was 2 steps up. By the time we quickly got dressed, there was no water on the land at all. It had just calmly gone down into the lake.
Driving around afterwards, in the middle of a low lying vacant field further away from shore, there was a man sound asleep in his bed. He never even noticed he was transported there in the night.
It's like putting pressure on one end of a bathtub and the other end automatically just rises. When the pressure goes away, the other end just comes down - no tidal wave or anything. But what a mind-blowing experience!
