Fishing at Pia Mill Reservoir, Kauai County, Hawaii

• Overview

  Pia Mill Reservoir sits within Kauai County in Hawaii. It lies 361 feet above sea level. Small at around 4 acres: two anglers spread out cover most of it. ‘Ōma‘o sits 1.2 miles from here and is the nearest stop. It is 112 miles to Honolulu, the nearest city. The nearest boundary is a fair way off. It is a working water rather than a showpiece.

• Where to Fish on Pia Mill Reservoir

  We hold no depth figure for this one. The arms fish better than the open middle whenever the water is up. Points where the flooded channel swings in are the reliable ones. Public wildlife records from this area list flathead grey mullet, blackchin tilapia, mozambique tilapia and mackerel scad. Reporting is uneven, so absence from the list means little. Work Pia Mill Reservoir in sections rather than trying to cover it.

• Seasonal Patterns

  Seasonal averages run from 68°F in February up to 75°F in August. Year-round warmth means year-round fishing, with early starts in summer. Heat pushes fish deep from June onwards, so start early. Spring and autumn carry the year; summer squeezes it into the ends of the day. At Pia Mill Reservoir the season follows that pattern closely.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No car park, ramp or path is recorded within easy reach of the shore. Barramundi and estuary fish want hard-bodied lures and soft plastics worked around snags and drains. Where access is informal, keep it that way by behaving. Where tickets apply, they are sold in the nearest town rather than on the bank. Should this one be busy, 'Oma'o Reservoir is 0.8 miles off.
