Q: At Heidecke Lake, are they limiting umbrella rigs to two hooks? —Jim

A: Yes. Heidecke, like Braidwood and LaSalle, the other two cooling lakes in northeast Illinois, has a two-rod restriction. In Illinois, umbrella rigs in waters with a two-rod restriction must have only two hooked lures to be legal. Umbrella rigs, which have multiple lures on one frame, underwent a revival for freshwater fishing when Paul Elias won a major bass-fishing tournament last fall with the Alabama Rig version of an umbrella rig.

WILD OF WEEK

Birder Alan Anderson was, aptly enough, at Songbird Slough on March 8 when he saw a crayfish. He asked Carl Strang, naturalist for the Forest Preserve District of DuPage County, about it. Strang sent this: ‘‘Rusty crayfish don’t leave the water, as far as I know, and certainly not with young. (Did you notice all the babies under her tail?) I’m pretty sure this is a grassland crayfish, Procambarus gracilis. This is a species that lives in tunnels on land (the tunnels extend down to water) and often comes out to forage on land at night. The crayfish you photographed is a female who has come out of her tunnel and is heading to water, where she will release the babies. They will grow for a time in the water before emerging to establish their own semi-terrestrial lives. This is within the time of year when this behavior is normal.’’
