Also, for those interested in the measurement and study of the lake water, here is a good page: https://www.nps.gov/crla/learn/nature/research-equipment.htm

We learned about the Secchi disk, which is a black and white disk only 8 inches in diameter. They slowly lower it until you can no longer make it out and record that depth. The record is 143 feet! Slightly subjective, but it's been used since the 1860s.

Neat article! I’ve been out on the Neuston to collect the sediment trap and CTD for semi-annual reset (before 2013, obviously). My dad was an oceanographer at OSU and I think designed that sediment trap, then retired around 2013…

Anyway, I wasn’t paid (so the opportunity was unique to me because of nepotism, but tax dollars weren’t being spent on me), and got to sleep in the boat house on wizard island and scuba in the lake. Extremely cool experience, part of a small-but-not-that-small group of people to have done those things.
