• Tackle & Baits

  Whether the bank is open is not something our records settle. Public data shows nothing built here, so treat the whole approach as informal. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Ask in the nearest town if you are unsure. Fishing rules and camping rules are set separately here. If the gate is shut, Hogan Lake at 0.4 km is the nearest alternative. Check the position on Mullen Lake before loading the car.
