Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Where the road in crosses private land, ask first. Where tickets apply, they are sold in the nearest town rather than on the bank. Should this one be busy, Guiney Lake is 0.9 km off. Nothing on Cotters Lake should be assumed from this page alone.
