Dialga/Palkia is lvl 47, so be prepared. Warning: Don't use a Master Ball, he's quite easy to capture. Around 30-50 Ultra Balls will do.
After you capture it, go back to the HQ, and talk to Saturn. He tells you that the boss has gone somewhere and didn't return, and that Saturn has taken over.
Heres a tip: For me, Dialga was easy to catch, but there are a few more Sinnoh Pokemon that are really rare and cannot be caught unless you have caught Dialga or Palkia. Another thing, to get to Sunyshore City, you gotta catch either Dialga or Palkia, that's what the "power outage" is about. Hope this helped!
you will go to there veilstone hq, looker will run up to u, you go in there warehouse, about where you got the professers helpers pokedex back.
go to snow point city and take the boat there to the (triangle Islands)

If you are asking as to why they are not there, it is because you probably haven't defeated Team Galactic on top of Mt. Coronet, they will appear at the lakes after you do. *this is for Pokemon pearl, diamond, or platinum*
The Pokemon for Lake Verity,Acuity,and Valor are:Mesprit for Lake Verity,Uxie for Lake Acuity,and Azelf for Lake Valor.Hope that helps!
lake acuity
The Storage Key opens the Galactic Warehouse in Veilstone City. It is dropped by a Galactic Grunt in Veilstone City after you beat Jupiter at lake Acuity.
by snowpoint city.
If you have Pokemon Emerald in your GBA Slot (this also works for Pokemon Pearl and Diamond) Pokemon Platinum- Route 217, Lake Acuity Pokemon Diamond & Pearl- Route 217, Acuity Lakefront, Lake Acuity
Mars does not appear at lake acuity. If you beat mars at lake verity then go to the upper part of mt coronet and explore until you reach snowpoint city. If you're at lake acuity and beat Jupiter then go to the galactic HQ in veilstone city.
Route 217, Acuity Lakefront, Lake Acuity
It is found at Lake Acuity. If you defeated it, it won't appear. Also, I think it appears after you defeat Team Galactic at Veilstone City.
in the island in the middle of lake acuity
go to acuity lake (must have rock climb) then talk to Barry, then go to galactic Veilstone HQ building, and from there to Spear Pillar
you get it near lake acuity
Because you're not using Platinum. -hope this helps
He went to the lake near twinleaf and you have to fight team galactic
