161-acre lake near Berkshire. The lake tops out around 16 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What follows comes from the same scoring engine that paints the spots above.
On the chart, Farnham Flint or Englefield Lagoon draws 161 acres inside 4.5 miles of shoreline. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 93% of the surface on the model — that's where the groceries are. Call it 0.7 mi long by 0.6 mi wide at the broadest reach. The water lies in West Berkshire. For a second option, Sonning Eye gravel pit lies 5 mi northeast.
Early season brown trout use the shallows, holding in 2 to 16 ft. Even in summer they hold at 5 to 16 ft; winter keeps them in 2 to 16 ft. The chart's best answer is Break off the point — drop-off, 7 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 16 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 16 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (7 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 16 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 16 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (7 ft) | Jigging spoon, Small stickbait (slow) |
Spring puts european perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 5 to 16 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 5 to 16 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 5 to 16 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 5 to 16 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
