one of my professors is doing a fish survey in metroparks and he said that he gets them pretty consistantly in swan creek. i have no idea about the size though. he surveys with a seine net so i would imagine they are small. the adults probablly can swim away faster than they can catch them. let me know because i was actually looking for a place for them too, i just haven't had time to go out and try. anything is possible, i caught a northern in the ottawa river last summer and i actually hooked a steelhead in the ottawa last week at the golf course. i was fishing for crappie or bass or whatever in the little pond to kill time and had a 1/16 jig. i walked to the creek to see if the white bass were in there yet and see a steelie, he took the jig but as i was about to land him the hook broke on the jig. would have been my first steelie. man was i mad,
