Yes, there is a reason for it - it's just not that good of a hard water lake (I put about 20 winter days there every year because is it very close to me so I can go for couple of hours whenever I like to). I rarely see others there.
There is a lot of good spawning water there so fish tend to spread all over (unlike some other local lakes where perch, pike and crappies are a lot more concentrated). Launch area bay is not that great of a spawning bay so perch can be hard to find. The other end of the lake is better in that regard but requires a lot of moving around and knowing the lake well. Good luck. Bring even bigger shovel!!
