We've been to Hastings at 8:00, nobody was there yet, and looked for fish for an hour. Never found them there. Moved to Clear creek next to a bunch of boats and got a dozen keepers, but was very slow and decided to troll back to Burwell. Ended up with 3 eyes. Around Sand Hills there were 2 extremely large nets running N-S a few miles apart. They had from place to place white buoys which made visible and avoidable. We caught all fish between the nets. By the number of fish we saw on fishfinder it must have been a lot of fish concentrated in that area, soon as we passed them the picture changed totally on the fishfinder, and we didn't catch anything anymore, so we called it off. A nice day but very tough fishing for us.
