you find it at map 5 or at that place with electric Pokemon
you have to make your way through the game. the three lake Pokemon are rare and than you can catch giritina. im not sure if you can catch both dialga and pialka. than there are more but you have to buy the Pokemon stratrgy guide to find the others like heatran corsilina and regigias
Regularly obtainable Pokemon: Diamond: Dialga at Spear Pillar Pearl: Palkia at Spear Pillar Uxie at lake acuity Azelf at lake valor Mesprit at lake verity (after interacting it will wander sinnoh) Heatran at stark mountain Regigias at snowpoint temple Giratina at turn back cave Cresselia at full moon island For more info, go here: http://www.serebii.net/diamondpearl/legendaries.shtml
