I find myself missing the one thing they lack.
You guessed it!
Real-time eco-hydrological presentations of data displaying exactly where the water is at now and where it's been for the past seven years relative to major ecological thresholds and seasonal statistical probabilities. I know where am but where is the water? Discerning hydrologic minds would like to know.
Then again, sometimes maps and graphs be darned ...
I just like to go out and get my feet wet.
Hydrographs and boardwalks have a way of keeping you away from that.
