A clean, cloudless night over the water, with flat calm through the day with the glass on the way up. Activity on Rim Rock Lake should centre on the shallows early and the drop later. The night should out-fish the rest of the day. Push the good hours hard and rest through the dead ones. Autumn rewards covering water while the fish roam.

Rim Rock Lake is set in Delta County, Colorado. The ground round it is rolling bush. This is a pocket water of some 13 acres, and every part of it is reachable from the bank. Nearest town is Cedaredge, 9.5 miles off. The nearest city of size is Boulder, 162 miles away. Being near a boundary, it pays to know which side you are fishing.
Nothing in our records gives a depth for this one. Standing timber shows when the level drops, and fish sit against it. Held water runs deepest at the wall and shallows back to the inflow. Delta County records list rainbow trout, white sucker and flannelmouth sucker among the fish reported. The list covers the county rather than this water alone, so treat it as a guide. On Rim Rock Lake the obvious spot is not always the productive one.
The seasonal spread runs 17°F to 56°F. Spring and autumn carry the fishing; summer and winter test it. Ice is part of the season here, ending near mid May. Averages place the thaw at mid May and the freeze at mid November. Late spring and early autumn carry the year between them. Expect Rim Rock Lake to follow that timing.
Access is not recorded for this water. A made slipway is half a mile from here, which settles the boat question. You can camp half a mile off, which suits an early start. There are toilets mapped about half a mile away. For the trout, small spinners and a box of nymphs cover both approaches. A phone call first saves an afternoon. Keep proof of licence with you rather than in the car. January Reservoir sits 0.2 miles off and takes the overflow. Check the position on Rim Rock Lake before loading the car.
