Here is what WF is talking about:http://www.amazon.com/gp/product/0899333303/103-3308805-8730221?v=glance&n=283155This is a great tool to have. WF (or anyone else) - not to hijack this thread, but this is kind of on subject, since it involves sloughs. You seem to be "in the know" with respect to lakes in the Day County/Webster area. Have you ever heard anything about a slough west of Lily, SD. It may be a GPA. In any event, I have been reviewing SD stocking reports, and the GFP has been dumping a lot of walleye fry into a Day County lake referenced as "Lily" for the last several years. I have never once heard so much as a whisper about this lake or about fish being caught there. One day last winter I took a drive southeast of Webster down by Horseshoe and Long Lakes and then over through the town of Lily and there was a place where the road ends just west of town where the road meets a slough. I am assuming this is the place. There was one portable out on the lake the day I was in the area. If anyone knows anything about this slough or what the story is there, I would be interested in hearing about it. Like I said, the SD fish stocking report is what led to my curiosity.
