34-acre lake near West Haven. CT DEEP survey water. The lake tops out around 18 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Maltby Lake #1 runs 34 acres with 1 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. You'll find it in South Central Connecticut County. The nearest mapped water is Maltby Lake #2, 0 mi to the north.
The spring pattern is a shallow one: rainbow trout in 5 to 18 ft. The depth story barely changes: 5 to 18 ft through summer, 4 to 18 ft in winter. Top water on the chart: Break off the point, a drop-off in the 8 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

Early season brown trout use the shallows, holding in 2 to 18 ft. Even in summer they hold at 5 to 18 ft; winter keeps them in 3 to 18 ft.

Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.

You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
