Where is the cheapest indoor public pool/outdoor public pool & yoga classes in placerville california?

I live in placerville california 95667 is the zip and I have been having the hardest time finding an indoor pool or even an outdoor public pool to use when its too cold to hop in the rivers here(for winter usage) So anyone that can inform me of where there is a cheap indoor/outdoor public pool thats available during the winter time will be greatly appreciated. Also where is a cheap yoga class location around here? most yoga places i find are over 50$'s im not sure if thats the cheapest or not but figured id ask. The yoga and pool places dont by any means need to be at the same location just somewhere near placerville. Please let me know the prices too Thanks
