84-acre stocked lake in the Mat-Su (Knik Arm) area. ADF&G sonar-surveyed water with stocked rainbow trout and 3 more species. The lake tops out around 20 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Memory Lake maps at 86 acres behind 2.5 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. About 86% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.6 mi of water from one end to the other, 0.4 mi at the beam. Matanuska-Susitna Borough claims this one. Kings Lake sits 2 mi east — the closest neighbouring chart.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Through summer count on 5 to 20 ft; the winter hold is 4 to 20 ft. If you only fish one area, make it Shallow feeding flat: a feeding flat around 20 ft that scores good in spring. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft | dawn & dusk | Shallow feeding flat (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Early season coho salmon use the shallows, holding in 2 to 20 ft. Even in summer they hold at 6 to 20 ft; winter keeps them in 6 to 20 ft. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + fly or a medium spoon above the thermocline and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 20 ft | dawn & dusk | open water | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 6 to 20 ft | dawn & dusk | open water | Dodger + fly, Medium spoon above the thermocline |
| Fall | 4 to 20 ft | dawn & dusk | open water | Casting spoon, Spinner (chartreuse) |
| Winter | 6 to 20 ft | midday | open water | Small spoon, slow troll |
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 5 to 20 ft. Plan around early morning in the warm months. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Summer | 6 to 20 ft | dawn | open water | Jigging spoon vertical, Tube jig (smelt) |
| Fall | 5 to 20 ft | midday & dusk | open water | Casting spoon (orange/gold), Beadhead streamer |
| Winter | 5 to 20 ft | midday & dawn | open water | Jigging spoon (glow/silver), Tungsten jig + plastic |
Spring chinook salmon on Memory Lake hold shallow, usually 3 to 20 ft. Depth-wise the year is flat: 6 to 20 ft in summer, 6 to 20 ft once it turns cold. The feeding windows run early morning and the evening. The summer box starts with a flasher + fly (green/white) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | open water | Trolled spoon (orange/gold), Stickbait off planer boards |
| Summer | 6 to 20 ft | dawn & dusk | open water | Flasher + fly (green/white), Magnum spoon on downrigger |
| Fall | 4 to 20 ft | dawn & dusk | open water | J-plug (glow), Flasher + fly |
| Winter | 6 to 20 ft | midday | open water | Small spoon on a slow troll, Stickbait deep |
