1,285 miles of mapped stream across 918 square miles of drainage in Livingston, Oakland, Washtenaw, Wayne counties, in 70 named streams. Michigan designates 184 of those miles as trout water, on 12 streams.
Open in BirdTrout50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands the app paints. On this map the colour is MDNR's classification of the valley segment, not a measurement, except at the gauge dots, which read live. Grey is water MDNR has not typed.
HUC8 04100013 in the USGS Watershed Boundary Dataset. Every figure below adds up the river pages in this basin — same records, one basin at a time.
MDNR's Valley Segment Ecological Classification, which types the valley segment rather than measuring the water. It covers 8% of this basin's stream miles (106.8 of 1,285); the rest is untyped and is drawn grey on the map above.
0.0 of the 106.8 typed miles in this basin — 0% — are cold or cold-transitional water. The dominant class is warm.
There is no elevation model behind this page, so it carries no elevation range. MDNR's gradient class is the field that answers the same question, and over the typed miles it reads: low 49.1 mi, medium 41.5 mi, very low 9.7 mi, high 6.4 mi.
The Huron River runs 129.4 miles through this basin and MDNR types it warm along its length. The basin's typed water carries no cold or cold-transitional reaches at all: 59.5 miles warm and 47.3 cool, out of 106.8 typed, which is 8% of the 1,285.2 mapped stream miles. 12 of the 70 named streams are designated trout water over 184.5 miles, and none holds a Blue Ribbon designation. Mill Creek, 20.9 miles of cool water, is the longest stream here that is not typed warm; Honey Creek, 16.9 miles, is untyped. The ground is the story of this watershed as much as the water. 83,961 acres are public — 14.3% of the basin — but they sit in 654 separate units and 53,223 acres of them are local-government land, with the state holding 14,774. MDNR's one survey station here recorded smallmouth bass.
All 70 of them, longest first. 12 have a page of their own and are linked; the rest are in the app. Thermal class is MDNR's, over the reaches it has typed. "Now" is the live USGS reading where a gauge stands in that stream.

The hatch calendar for southern lower Michigan, which is the region this basin's centre falls in — the same regions the app's hatch panel uses. It is a regional record, not a survey of this watershed: nobody has counted insects basin by basin. Year-round records (midges, scuds, sculpins) are left out; they are true every month and they are not what a calendar is for.
47 insects are recorded from southern lower Michigan. Each links to its own page, with the flies that imitate it.
The subbasins that share a boundary with this one and carry coldwater streams.
The weekend this basin adds up to — the biggest water in it, what is hatching when, the public land in range and a three-day plan.
