Not exactly a lake... more like a long muddy pools formed by the drainage system   ... very tricky to go there...  There's only one narrow entry point for cars surrounded by residential gated communities .. with bicycle logo imprint on the sidewalk at the entry side ... When inside just walk along the path with lots of pokestops .. they keep spawning along the straight path.. 

I think the guard post is for the residential gated communities.. Don't think they allow you to enter but I might be wrong... I used the other side open for public.. Sorry no gps, but I used waze.. If you reach the guarded post just continue since its in a circle.. the entrance is at the other side.. slightly hidden.. with a big bicycle logo on the sidewalk entrance.. Good Luck, 

Thanks for the feedback, i guess i will pass on Shellder for now 

Also some feedback from me

Taman Desa Recreational Park: Kabuto and Seel spawn not often. Only caught 1 Seel during my 1 hour stay.

Ara Damansara Park: Managed to get 5x Kabuto within an hour. Based on my 2 days trip

Holiday Inn Glenmarie: Managed to get 11x Omanyte within 45 mins. Suggest to go late night when the clubhouse is close

Confirmed pikachu nest
