FishinRod, thanks for the good thoughts. I put some water in jars yesterday and so far it looks equally cloudy, so maybe I need a flocculant.

What do you think?

Esshup I was considering buying a Hanna, something like this: https://www.hannainst.com/hi9146-portable-dissolved-oxygen-meter.html You raise a good point that it could be too late by the time I notice.

Journeyman it is five 2 disk stations, spread out around the pond. You have a good point about the leaves. We do get quite a bit. Our hope is most of these leaves will get sucked into the stream before they sink to the bottom, but it is an untested theory so far as this is our first fall with the stream running. We should learn more soon though.

Ted, talk to them and see if you need to move the probe at a certain speed to get an accurate reading. IIRC the YSI membrane probes have to be moved at a rate of 1 foot per second and they take up to 15 minutes to warm up and stabilize once turned on.

I use a YSI optical O2 meter. No need to move the probe, and it reads within a minute or so of turning on. But it is a bit more pricey than the Hanna unit.
