Spinner,
I graduated from Mt. Hood in 1990. That pond is EASILY accessible by anyone and everyone. It's almost always crowded. So, go early if you can.
BTW, the ODFW schedule indicates that it will be/was stocked the "week of" the 17th. Rarely is a stocking done on Monday. But, it will be done "sometime" during that week. So, it likely has been stocked by now.
There is a state park, with a dock, at Detroit. I fished there in June. I C & R'd over 30 trout from one pocket of water that day. Then found more trout the next day, in another pocket. If you have time, it's worth the trip...especially if you can stay a day or two. There is a day use fee.
