It is 0.5 miles if you were to walk on the outer sidewalk that's furthest from the lake, by the road. How I came up with the answer? Zoom into lake, select a point on the sidewalk surrounding the lake. It should pull up longitude and latitude coordinates. There will be an option that says measure. Follow the sidewalk around the lake.
3 mile radius.
Around just the lake itself i would say it's more like a mile or mile and a half
3 mile loop
