Fresh or salt water fishing the second week of April

My family and I are going to be in Washington and would like to do a little fishing with out spending a load. Please fill me in to the best spots and gear to catch them. We do have some salt and fresh gear.

The only reason that I say this is that ALOT of the Freshwater Lakes in Eastern Washington anyhow, do not open for season until the Last Weekend in April - the 25th.
There are a couple of Lakes in the Spokane / Medical Lake area that are open all year round - Silver Lake, Lake Spokane ( found under the Spokane River Resevoir ). Check the Angler's Guide under the Tackle Box Tab - Eastern Washington Lakes
