I would definitely go with the FHM & GSH for initial forage.

Crayfish would be good IF you can get a native species that does well in ponds - no idea what that might be in Wash state.

Other fusiform (torpedo-shaped) fish could be a good addition, especially if they have the potential for long-term forage. Can you stock YP out there?
