No further info, but since in February it is often too cold to swim and early February is typically a slow time of year, this is when they do things like pool and water park refurbishments so I'm not surprised. I was at POR in September and one of the quiet pools was closed - and it was 90 degrees! If it does get warm enough to swim while you're there, I am sure all 4 of the quiet pools and the POFQ pool will be open.
