Interesting...I heard they were making their way into the river. Checked it out this morning and just like you said, didn't see any! Not sure if they're just starting or just finishing up. Hope I didn't miss it.
Sounds like the suckers were getting illegally netted out of the river. Since the culprit(s) was caught and cited, additional suckers may have made there way back in the river doing their thing. Not sure why they were netting when it's so easy to catch them with a SJ Worm.
