Source data no longer reliable

No longer helpful and reporting is so delayed- one might as well drive dowm and have a look at the creek themselves

You ruined it.

You people have ruined what once was a great tool. Can not move map to look for other monitor sites. Map keeps coming back to my location. I don’t want alphabetical order I want west to east order like I had it setup before you changed it. Please advise, send phone number for consultation.

Excellent app

Layout change

I used the old layout style very often (im a fisherman)
Not sure why the layout changed, but I don’t like it. I’d rather know the CFS instead of water height
