Prosperous Lake Fishing Guide, North Slave Region, Northwest Territories

• Overview

  Prosperous Lake is a North Slave Region water, Northwest Territories side. Height above sea level is 214 metres. Surface area runs to some 35.79 sq km, so a boat and a plan are both worth having. Some 96 km of shoreline means conditions can differ from one end to the other. 18 km away sits Yellowknife, the nearest town. Edmonton is the closest city, 1007 km away. It lies deep inside the county rather than near an edge.

• Where to Fish on Prosperous Lake

  Nothing in our records gives a depth for this one. Weed, then depth: that is the order to fish a water of this kind. On a natural lake the weed line and the shelf beyond it do the work. Across North Slave Region, recorded fish include Arctic grayling, lake trout and slimy sculpin. These are county-wide records, so not all of them will be in this water. Treat Prosperous Lake as a water to read rather than to cover.

• Seasonal Patterns

  On the long-term average, July reads 16°C and January reads -27°C. The season is measured in weeks rather than months. Count on hard cover from midwinter, and open water from late May. Averages place the thaw at late May and the freeze at late October. The weeks after the thaw and the ones before the freeze are the strongest. Anyone fishing Prosperous Lake regularly works to that calendar.

• Tackle & Baits

  No access rule appears in what we hold. It formed naturally, so levels move with rainfall rather than with a gate. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Look for a notice board at the entrance. Signs go up and come down, so check on the day. If the gate is shut, Walsh Lake at 3.9 km is the nearest alternative. Ask locally about Prosperous Lake if anything is unclear.
