Looking north of Anoka for a lake? Here's the quick version on Lake George.
How big is Lake George?
The DNR's 2025 aquatic plant survey puts Lake George at 517 acres. That's a real lake, big enough to boat and fish, not a pond with a few docks on it.
How deep is Lake George?
The deepest spot is 32 feet. But most of the lake is shallow. The DNR counts 383 acres as littoral, the shallower water where plants grow. That's about 74% of the lake.
So ask how deep the water is off the end of the dock on the exact lot you're looking at. On a lake like this, it changes a lot from one shoreline to the next.
Why do people like Lake George?
The DNR describes it as a lake with a long-standing reputation for largemouth bass, with good water quality and lots of cover. Northern pike are abundant, and the DNR says there are some real trophy bass in there.
In winter, the DNR notes the shallow, sandy shoreline and clear water make it a good lake for darkhouse spearing.
Where's the public access?
The boat launch is inside George Lake Regional Park, run by Anoka County, and there's a fee to enter the park. You get there by heading north from Highway 10 on Anoka County Road 9.
Does Lake George have invasive species?
Yes. Eurasian watermilfoil showed up at 22% of the DNR's survey points in 2025, up from 18% the year before. The Lake George Improvement District organized a 2025 treatment covering 32.2 acres to target it.
