No border sits close enough to matter.

• Where to Fish on Slack-Weiss Reservoir

Records held for Jackson County cover brown trout, brook trout, rainbow trout and Arctic grayling. Read it as a county summary, not a water-by-water list. Slack-Weiss Reservoir gives up its fish to patience rather than distance.

• Seasonal Patterns

  The range across the year is 19°F to 57°F. Hard water is a season in its own right here. After early May the shallows warm and the fish move up. Climate averages put the opening at about early May and the closing near mid November. The first weeks of open water and the last are the ones to plan for. Slack-Weiss Reservoir runs to its own calendar within the local pattern.

• Tackle & Baits

  Nothing in our records says who may fish here. A campsite lies half a mile away for anyone staying over. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Parking space is the usual limit rather than the bank itself. Some stretches are reserved and marked as such on the ground. Should this one be busy, Ninegar Reservoir is 0.2 miles off.
