• Tackle & Baits

  Nothing we hold confirms whether access is permitted. There is no recorded infrastructure here; expect to find your own way in. Carp respond to sweetcorn or boilies fished patiently on the bottom near feeding areas. State or provincial rules still apply whatever the bank status. Where the way in crosses private ground, ask first. For a change of water, Lord Reservoir is 3.5 miles distant. None of that is settled for Olds Reservoir in what we hold.
