Must have app if you love SML

Simple, value added app. One of my favorites! Nice quick reference for lake level and trends. Also provides a nice Windy weather app forecast as well as location of the awesome Ice Cream Boat. No ads, data tracking or other annoying stuff. Thank you for a great app!!

Alerts

Thank you for providing this great app!

One suggestion is to enable in-app alerts when the water level exceeds certain levels such as normal or fixed dock.
