287-acre lake in Sudbury District, Ontario. The lake tops out around 50 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Augusta Lake maps at 288 acres behind 6.1 miles of shoreline. The 2.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 88% of the surface — that's where the groceries are. Figure 1.5 mi of water from one end to the other, 0.9 mi at the beam. It sits in Sudbury District. Arts L. sits 0 mi north — the closest neighbouring chart.
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 15 to 50 ft, wintering in 15 to 50 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 50 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 9 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
