About the Black Hawk Creek
Black Hawk Creek drains roughly three hundred square miles of Grundy and Black Hawk counties and runs northeast to join the Cedar River at Waterloo. The gauge sits at Hudson, a few miles above the mouth. The creek gives its name to the county and to the Sauk leader, and it is one of the larger direct tributaries entering the Cedar in this reach.
The upper watershed is flat, intensively farmed and heavily tile-drained, and the creek there is a modest prairie stream in a cut channel. As it moves downstream toward Hudson the valley deepens, limestone comes closer to the surface, and the creek develops the riffle-and-pool structure that makes it worth fishing. Rock ledges, gravel bars, and deep bends against timbered cut banks are the features that hold fish. Water is usually turbid in spring and after rain, settling to a workable green in a dry summer stretch.
Smallmouth bass are the main quarry and they use the rock and the current seams exactly as they do on the better-known Iowa streams nearby. Northern pike are the pleasant surprise here, holding in the slower weedy stretches and the backwater sloughs and reaching genuine size in a creek this modest. Walleye push up from the Cedar in spring. Channel and flathead catfish take the deep holes, largemouth bass occupy the slackwater, and rock bass, bluegill, white sucker, freshwater drum and common carp round out a long species list.
Wading is straightforward at summer flows and the lower creek will float a kayak most of the year. The creek comes up fast after storms and drops back within a couple of days, so the Hudson gauge is worth a look before committing to a drive.
Hudson, Cedar Falls and Waterloo are all within a few minutes and cover lodging, fuel and tackle.
