5.1 mapped river miles, draining 4 square miles, in the Pine basin watershed.
50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.
There isn't one. Minnesota DNR publishes no temperature classification for any water in Minnesota. What it publishes is the Chapter 6264 listing below — a land-use protection under Minnesota Rules, not a thermometer — so this river draws grey on the map above, and grey here means unmeasured rather than warm.
MN DNR lists Spring Branch under Minnesota Rules Chapter 6264 as designated trout stream. Chapter 6264 is a land-use rule — its stated purpose is timber harvest and watershed permitting, with recreation second. It is not the season and creel rules, which change yearly and live with the agency, and it is not a statement about temperature.
