Yosemite, what are the goals for your pond?
At your elevation and being spring fed, my bet is your ponds stay rather chilly year round. This may not be conducive to growing warm water game fish very well...
Managing typical game fish in smaller ponds, say less than 1 to 2 acres is very challenging without extensive management efforts. If one doesn't feed and take an active management role, expectations for such ponds should be very minimal.
