All change - not sure why !

I thought I would return to the lake for another crack at the freshly stocked rainbows in the club lake. I took up position at yesterdays hotspot using the same tactics that had proved so effective. For whatever reason the action was slow to come. Maybe the fish were elsewhere so I tried different areas of the lake. I did finish up with 4 fish eventually but something had changed. Trying to figure out what it was will keep me thinking until the next visit. This 4lb fish was the first fish caught and the best fish of the day - taken on the white lure shown at the last trip.
