Rollins Creek, Minnesota

3.5 mapped river miles, draining 3 square miles, in the Baptism Brule basin watershed. No gauge stands in it; the nearest is 29.4 miles away, and it is the only temperature evidence on this page — what Minnesota DNR publishes is the Chapter 6264 listing below — a land-use protection under Minnesota Rules, not a thermometer.

Water temperature — the colour of the river, and of every dot on it

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.

The nearest gauge, and why there is no reading from it

The nearest gauge, 29.4 miles away at Baptism River Near Beaver Bay, is not reporting water temperature: USGS carries no water-temperature series for it at all. A stopped gauge repeats its last value in silence, so there is no live temperature here. Nor is there a model to put in its place: that gauge has too little record to fit one, and this site does not print a temperature it cannot stand behind.

The pills above go to USGS. These are this site's pages for the same gauges — a thirty-day chart, the monthly means, the record, and today's reading against the five-year normal for today: 04014500.

Thermal classification

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. The only temperature on this page is the live reading from the nearest USGS gauge, 29.4 miles away; it is a reading of that water, not this one.

Questions about this river

MN DNR trout stream designation

MN DNR lists Rollins Creek 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.

Species

Minnesota DNR designates this as trout water — Designated trout stream — without naming the species. No fish survey or stocking record for this water is in the files this site reads.

Hatches on this water

42 insects are recorded from northern Wisconsin, across the state line. No insect records in this dataset are filed under Minnesota, so these are the nearest ones — the same landscape and the same water, on the other side of the border, and not a survey of this stream or even of this state. Open the river in the app and the hatch panel will narrow it to the ones whose temperature window today's reading is inside.

And 28 more — the year-round records, mostly: midges, scuds and sculpins, which are in the water every day and are therefore never the news.
