I've noted that the River gauges give a turbidity rating using the FTU scale.

The attached shows what the FTU number ratings indicate.

Looks like below 100 is what I'd like to see, below 50 would be ideal. Right now I think they are between 50 and 80 at Little Falls..there about...

Any thoughts on turbidity ratings?

Thanks for sharing this. Honestly I've never given it much thought. 2 summers ago I fished the McLoud River and it looked like 1000 on the scale because it's glacial. The trout didn't have a problem seeing my nymphs.

Glacial silt behaves a little differently than some of the dark sandy clay silts like we have here, it typically looks worse to the naked eye than it really is, and its so fine grained that I'm not surprised trout can see well in it.
