In Oregon, Upper Rock Lake falls inside Clackamas County. It sits at 4,416 feet above sea level. The closest town, Mount Hood Village, is 15 miles away. Beyond it, Estacada at 20 miles and Sandy at 22 miles. Others within reach: Rock Lakes 0.2 miles off, Lower Rock Lake some 0.7 miles off, Shellrock Lake 0.8 miles off, Serene Lake some 1 mile off and Hideaway Lake 1.7 miles off. No boundary runs near, so the county rules hold throughout.
The records we hold are silent on depth, so plan to find it yourself. Look for the band where the shallows give up and the bottom falls away. This is a lake, so the margins and the first drop matter most. Fish documented in Clackamas County include Coho salmon, rainbow trout, Chinook salmon and cutthroat trout. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. On Upper Rock Lake the first feature you find is usually worth a session.
Expect August near 58°F and January near 31°F on the long-run figures. The year gives four workable seasons without severe ends. Some winters give nothing at all, so plan for open water. April and May are the settled weeks, with October close behind. Upper Rock Lake runs to its own calendar within the local pattern.
No access rule appears in what we hold. There is no recorded infrastructure here; expect to find your own way in. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Bank access can be seasonal on ground like this. Close seasons apply to some species and not others. Rock Lakes sits 0.2 miles off and takes the overflow. Nothing here settles the position at Upper Rock Lake for certain.
