Rock River is a public river in Whiteside County, Ogle County, Winnebago County, Rock Island County, Lee County and Henry County, Illinois, managed by State of Illinois (public / navigable water). You can fish it on an Illinois licence; bank access is at road crossings, parks, IDNR sites and other public land, and riparian owners control the bank on non-navigable reaches. Public access confirmed via marquee water.
The Rock River across northern Illinois — smallmouth bass, walleye, sauger, largemouth bass, and channel and flathead catfish in a wide, historically industrial river that has recovered strongly.
It runs roughly 161 miles through the Northern Illinois region. Anglers here mostly fish for smallmouth bass, walleye, sauger, largemouth bass; channel catfish, flathead catfish, white bass are also on record. Live flow and gauge height come from the Rock River At Byron, Il USGS station shown below. The nearest other mapped waters on PiscaMaps are Threemile Branch and Sugar Creek.
Species from IDNR fishery-management data.
Night fishing: No statewide night-fishing closure in Illinois. Some IDNR site lakes post hours or gate at dark, and a handful of urban lakes are day-use only. Trotlines, throwlines and set hooks are legal on most rivers and reservoirs (not on IDNR-managed quality lakes) with the gear tagged; bowfishing for carp, gar and buffalo is popular after dark on the big rivers.
Boats: Rend, Carlyle, Shelbyville, Clinton, the Mississippi, Illinois and Ohio rivers have no horsepower limit; idle / no-wake zones are marked near ramps, dams and marinas. Many IDNR site lakes are electric-motor-only or have a horsepower cap posted at the ramp, and several Chain O'Lakes waters have summer speed-zone rules. Illinois requires a boater-safety certificate for operators born after 1 Jan 1998.
Bank & bivvy camping: Camp at Illinois state parks and recreation areas on the big reservoirs (Rend Lake, Carlyle, Shelbyville, Clinton, Kinkaid, Crab Orchard), the Shawnee National Forest in the south, and IDNR site campgrounds on many of the managed lakes. The Mississippi, Illinois and Ohio rivers have Corps campgrounds and river-access parks.
Tackle: Statewide black-bass daily limit is 6 (14-inch minimum on most water, with special slot or catch-and-release rules on IDNR quality lakes); crappie 25 on most reservoirs; muskellunge 1 (36-inch minimum, higher on trophy waters); walleye/sauger limits vary; catfish generous. Check the current IDNR digest of fishing regulations for this water.

Anyone 16-64 needs an Illinois Department of Natural Resources fishing licence — the resident annual is about $16 (a resident Sportsmen's Combination that adds hunting is more), the non-resident annual about $32, and non-resident 1-day/5-day licences are sold. Illinois has no trout stamp requirement for most water (a small number of put-and-take trout ponds may need a separate stamp — check locally); Illinois residents 65 and older, and anyone under 16, do not need a licence. A single licence covers the state's Corps and IDNR reservoirs. Buy from IDNR at dnr.illinois.gov. An Illinois fishing licence covers navigable rivers. The Mississippi is fished on an Illinois, Iowa or Missouri licence in the border reaches; the Ohio on an Illinois, Kentucky or Indiana licence; the Wabash on an Illinois or Indiana licence.
