Largemouth bass from the mainland and peacock bass from South America have been planted in more than 100 reservoirs on Kauai. The impoundments range from tiny farm ponds to the 500-acre Waita Reservoir. The downside is that the reservoirs are privately owned. They were constructed as irrigation reservoirs for pineapple and sugar cane plantations and only a couple of guides have gained access. It’s worth looking up one of these outfitters, however, as both types of bass hit topwater lures with a bang. Hiring a guide for a full day costs about $275 for two people, while a half-day runs about $150 for two people. Live bait and bass lures, including crankbaits, spinnerbaits and topwater plugs, produce fish. Most of the peacocks and largemouths are in the one- to three-pound class, but some weigh as much as eight pounds. A freshwater gamefish license is required ($5 for residents; nonresidents pay $10 for seven days, $20 for 30 days and $25 for the year).
