17.6 mapped river miles, draining 120 square miles, in the Castle Rock basin watershed. No gauge stands in it; the nearest is 28.9 miles away, and what this page knows about its temperature is Wisconsin DNR's classification of the water itself.
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 is 28.9 miles away, at Red River At Morgan Road Near Morgan, Wi — not a reading of this water, but of what the region is doing today.
The Plover carries all three of Wisconsin DNR's classes — Class I, Class II and Class III, managed as wild, wild supplemented and stocked — and the thermal typing runs Cold ahead of Cool by four to one: 30.1 miles against 7.5, out of 37.6 typed, 57 per cent of its 66.13 NHD miles. Just over half the river classified is a sample, and these pages cannot say which end each class falls on. There is no gauge in it and no measured temperature. The channel is 19.2 feet across at the median, fourth order, draining 120.3 square miles over the 17.6 miles of axis mapped. Public ground is two overlapping spring-pond parcels fronting two-thirds of a mile each. Pike Lake Creek comes in at river mile 9.6.
Wisconsin DNR's classification of this water, reach by reach. A class, not a temperature — no July mean, because none was measured here.
| Reach | Typed miles | Band | Wisconsin DNR type |
|---|---|---|---|
| RM 17.6–6.8 | 30.1 | cold | — |
| RM 0.0–0.0 | 7.5 | cool | — |
Wisconsin DNR has classified 37.6 of the 66 miles NHD carries for this stream — 57% of it. The typed water splits 30.1 mi cold, 7.5 mi cool. The untyped reaches are not warm water — they are water Wisconsin DNR's inventory does not reach, and the mile ranges above span only the reaches it does.
Anglers name parts of this river. These are the names two or more independent sources use; each page says which sources, because a nickname is the one thing on this site that is not a measurement.
Wisconsin DNR classifies this water as Class I, Class II, and Class III. More than one class appears because the classification changes along the river. The thermal bar above shows where. The management tier on those reaches is stocked, wild, wild supplemented. This is a designation of the fishery, not the season and creel rules — those change yearly and live with the agency.

2 units of public or open-access land touch this river, 1,550 acres in total. Acreage is the whole unit, not the part beside the water.

| Statewide Spring Ponds - Wd | state natural-resources agency | 353 |
WDNR has stocked brook trout into this water 3 times between 2015 and 2017. That is a stocking record rather than a survey — it says the fish were put in, not that a survey has found them since.
42 insects are recorded from northern Wisconsin, which is the region this river sits in. That is a claim about the region and not a survey of this stream: nobody has recorded which of them has been caught here. 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.
1 named stream meets this one. Confluence miles are above the mouth; the longest twelve are listed.
Plover River sits in HUC 8 07070003, the Castle Rock basin, and drains 120 square miles, Strahler order 4 at the mouth. 72 NHD reaches carry the name for 66.1 miles in total — more than the 17.6 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
