• Tackle & Baits

  Our records carry no access rule either way. Public mapping records no formal access here, so plan for a walk and soft ground. For the carp, bait a margin spot and sit on it; corn and bread still work. Check whether a boat is allowed before you tow one. Some stretches are reserved and marked as such on the ground. Sweet Lake at 1.9 miles is the sensible second choice. None of that is settled for Johnston City Sewage Lagoon in what we hold.
