In a large mixing bowl, combine the cream cheese, sour cream, and mayonnaise until smooth and evenly mixed.
Add the salmon, lemon zest, lemon juice, dill, chives, Worcestershire sauce, paprika, pepper, and garlic powder. Stir gently until combined.
Transfer to a serving bowl, cover, and refrigerate until ready to serve. (see note). Arrange crackers, chips, or veggies around the bowl for dipping. Garnish with extra dill and chives if desired.
Notes
Store leftovers in the fridge in an airtight container for up to 2 days.
The dip will be quite firm right from the fridge. It's best to let it sit out on the counter for 30 minutes before serving to soften it back up. You can serve it chilled, but it'll be more like a spread than a dip.
