What Glen Island offers and where to find it
Glen Island sits in the southern basin of Lake George, roughly midway between the western shore near Glens Falls and the eastern shoreline. The island itself is small and rocky, but the real fishing happens in the shallows surrounding it — water that rarely exceeds 15 feet and often runs 6 to 10 feet deep. Both smallmouth and largemouth bass hold here year-round, with smallmouth dominating the rocky structure and largemouth tucked into the weed edges on the south and west sides.
Access is by boat only. Launch from Hearthstone Point Public Campground on the western shore (a New York State Parks facility with a fee), or from the public launch at the north end of Lake George Village. Glen Island lies roughly 2 to 3 miles north of the village launch, depending on which side you approach from. The island has no landing area and is not a destination in itself — you fish the water around it.
Key Takeaways
- Glen Island's shallow, rocky perimeter holds smallmouth bass year-round, with the best fishing in spring and fall when water temperatures stabilize.
- Largemouth bass congregate in weed beds on the south and west sides, particularly in summer when aquatic vegetation is thickest.
- Boat access is required; launch from Hearthstone Point or Lake George Village, both with parking and facilities.
- Soft plastics, crankbaits, and topwater lures work well on the rocky structure; spinnerbaits and weedless presentations work better in the vegetation.
Seasonal patterns around Glen Island
Spring (April through May) brings smallmouth into the shallows as water temperatures climb from the 40s to the mid-50s. Fish the rocky points and drop-offs on the north and east sides of the island with small crankbaits and soft plastics. Largemouth move into the weed edges later in spring, usually by late May when the water reaches 60 degrees.
Summer (June through August) shifts the bite to early morning and late evening. Smallmouth retreat to slightly deeper water (12 to 15 feet) around the island's perimeter, but they still respond to topwater lures at dawn. Largemouth stay shallow in the weeds; throw spinnerbaits and weedless soft plastics along the vegetation lines. Midday fishing is slow unless you work deeper structure or shade.
Fall (September through October) is often the most consistent season. Water temperatures drop back into the 50s and 60s, and both species feed aggressively. Smallmouth return to the shallower rocky areas, and largemouth remain active in the weeds. This is when you can catch fish throughout the day, not just at dawn and dusk.
Winter (November through March) slows the bite considerably. Ice forms on Lake George most years by late December. If you fish before ice-up, focus on the deeper edges around the island (15 to 20 feet) with small jigs and live shiners. After ice forms, ice fishing is possible but requires checking current conditions and local regulations.
Tackle and lure choices for Glen Island structure
Smallmouth on the rocky structure respond best to 1/4- to 3/8-ounce crankbaits that mimic shiners and dace, the natural forage around the island. Rapala Shad Raps and Berkley PowerBaits in silver or natural colors work consistently. Soft plastics — 3- to 4-inch worms and shads rigged on 1/8- to 1/4-ounce jigs — let you work the rocks slowly and feel the bottom.
Topwater lures produce strikes in low-light conditions, especially in spring and fall. Small poppers and walk-the-dog baits create commotion that draws smallmouth from deeper water. Cast toward the rocky points and work the lure steadily back to the boat.
Largemouth in the weed beds need weedless presentations. Spinnerbaits with willow-leaf blades (1/2 to 3/4 ounce) helicopter through vegetation without fouling. Texas-rigged soft plastics — 5- to 6-inch worms in dark colors — let you punch through thick mats. If the weeds are sparse, a shallow-running crankbait can work, but expect snags.
Line choice matters on the rocks. Use 8- to 12-pound fluorocarbon for crankbaits and soft plastics; it's less visible and abrasion-resistant. For topwater and spinnerbaits, 10- to 15-pound braided line gives you better hook sets and control in weeds.
Water depth and structure details
The north side of Glen Island drops off gradually from 6 feet to 12 feet over about 50 yards. This transition zone holds smallmouth, especially in spring and fall. The rocky bottom provides cover and attracts crayfish, the primary food source for smallmouth in Lake George.
The east side is steeper, with rocks and boulders creating a more dramatic drop to 15 feet. This is a good secondary spot when the north side is crowded or when you want to fish slightly deeper structure.
The south and west sides are shallower and weedier. Aquatic vegetation — primarily curly-leaf pondweed and coontail — grows in 4 to 8 feet of water. Largemouth hold along the weed edges and inside pockets of open water within the vegetation. Work these areas slowly and methodically.
Timing your visit and managing crowds
Glen Island is popular, especially on weekends during spring and fall. If you want solitude and consistent fishing, plan a weekday trip. Early morning (first two hours after sunrise) is productive and quieter than midday.
Summer weekends draw recreational boaters and swimmers, which can disrupt fishing. If you fish in summer, go early or wait until evening. Fall weekdays offer the best combination of good fishing and fewer boats.
Check Lake George water conditions before you go. Wind can make the shallows choppy and difficult to fish. Calm mornings are ideal for sight-fishing the rocky areas and working topwater lures.
Regulations and what to know before you fish
New York State regulates Lake George. Smallmouth bass have a 12-inch minimum length and a daily limit of 5 fish. Largemouth bass have a 12-inch minimum and a daily limit of 5 fish. Possession limits and season dates can vary, so check the current New York Department of Environmental Conservation (DEC) fishing guide before you launch.
A New York State fishing license is required for anyone 16 and older. You can purchase a license online through the DEC website or at most bait and tackle shops around Lake George. A one-day license is available if you don't want to commit to a full-year license.
Boat registration is required for any motorized vessel. If you're renting a boat, the rental facility handles registration. If you're launching your own boat, verify that registration is current before you leave the launch.
Nearby alternatives if Glen Island is crowded
If Glen Island is packed, the rocky shoals north of Carleton's Prize (another small island nearby) hold similar smallmouth populations and see fewer anglers. The western shore near Hearthstone Point has shallow rocky structure that produces well in spring.
The deeper basin south of Glen Island, around 20 to 30 feet, holds largemouth and some larger smallmouth in summer. This area is less crowded and can be productive if you're willing to fish deeper structure with jigs and live bait.
Frequently Asked Questions
What's the best time of year to fish Glen Island?
Spring (April–May) and fall (September–October) are most consistent. Water temperatures are stable, fish feed actively throughout the day, and you're not competing with summer recreational traffic. Summer can be productive early and late in the day, but midday is slow.
Can I fish Glen Island from shore?
No, Glen Island is accessible by boat only. You must launch from Hearthstone Point or Lake George Village. If you don't have a boat, consider renting one from a local marina or fishing guide service.
What size bass can I expect to catch?
Smallmouth typically range from 10 to 16 inches, with occasional fish pushing 18 inches. Largemouth average 12 to 15 inches. Glen Island is not known for trophy fish, but it's reliable for consistent action and solid-sized bass.
Do I need a guide to fish Glen Island?
No, the island is straightforward to locate and fish. If you're unfamiliar with Lake George or want to learn the structure faster, a local guide can accelerate your learning, but it's not necessary for success.
What should I bring for a full day of fishing?
Bring sunscreen, water, snacks, and a hat. Weather on Lake George can change quickly, so pack a light rain jacket. A depth finder or GPS is helpful but not essential if you're fishing the visible rocky structure. Bring extra tackle — the rocks will snag and break lures.
