Well no one can totally guarantee when a stocking has actually been completed. Employees call in sick and/or ODFW is maybe understaffed, trucks occasionally break down, bad weather, etc. can all delay or cancel a projected planting. I'd have doubts that it's any better in Washington, or anywhere else.
However, I totally get it. I've traveled to places over the years where I expected it to be stocked. Only to find zero fish. It's frustrating for sure. So I--among many others I am sure--do wish that ODFW would restart their stocking confirmation phone recordings again.
