Where an agency publishes a figure, we show it with the time it was taken; here there is none. Water level is missing from this page on purpose: no public feed covers Georgetown Lake.

Most Montana day-use areas open for the summer season and close outside it. If the water looks like pea soup or paint, stay out and report it to the managing agency. There is no water temperature sensor here, so only air conditions are shown.
