How big is gull lake say compared to sauder (rattlesnake)

[fluxcore]

I was supprized to find out after doing the math that gull lake has over 7 1/2 times the surface area (7.6 !) as sauder res (rattlesnake). Although rattlesnake has some deeper spots gull lake has a mean overall dept of 18ft and rattlesnake is only 12ft. Didn't realize how big sylvan & gull lake actually are.
