7:30 AM until 12:00 Noon – Registration starts at 7:00 sharp.
Lower Mountain Fork River; Broken Bow, OK


Starting Point – Canoe and Kayak Rental Parking Lot across the bridge from BB Fly Shop.
Pairings will be drawn just prior to the start.

The Rules are Simple

  • As the name implies, everyone gets the same one fly but you won’t know what it is until the morning of the tournament. No bait, lures or droppers (An M-80 is NOT a fly).
  • You do NOT have to be a current dues paying member of the LMFRF.
  • Entry Fees are $50 for current members and $75 for non-members. The $75 fee makes that person a member.
  • Each contestant will be provided the exact same fly pattern. This fly will be the only fly eligible for use in the contest. The fly pattern will be kept secret until the start of the contest.
  • You may only fish one fly at a time.
  • As this IS a fun fundraiser, there will also be the availability to purchase ONE identical “Mulligan” fly. But only PRIOR to the start of the tournament./li>
  • Each contestant will fish that fly (flies) ONLY. Lose the fly (flies), you are out.
  • The fly may be cut off the leader and retied as needed.  Your partner must be notified that you are doing this.
  • A fly that is broken off on an obstruction may be retrieved and retied to the leader. Your partner must be notified that you are doing this.
  • A scored fish is one that is brought to hand and released; no “LDR’s”. Your partner must be notified that a fish has been landed and scored.
  • Each contestant is responsible for keeping his or her own score.
  • A “Mulligan” fly of the same pattern may be purchased BEFORE the beginning of the tournament. Once the tournament starts, mulligans cannot be bought.
