hi everyone im new to the forum,had a question about water temp.I went out of sandy creek yesterday morning and started in 100fow started picking up some small fish in 110fow,fished 110 to 160 for couple hours caught 7 small fish decided to move out.got a 9lbs king in 250fow hung out awhile nothing else.Decided to try deep.Ran to 450fow put a rigger in 50 down and water temp was 40 degrees.Im not very experinced fishing deep and first year with down temp on ball.I was wondering if it is unusual to find water that cold that close to the surface out there or if it is normal?Bye the way i trolled from 450fow to 550fow and didn't mark a thing so i pulled em and headed in
