Bright, clear skies over the water today, with a soft NNE wind with pressure dropping. Whatever swims in Upper Derby Lake should be near the first drop-off and weed lines. Bank on the middle of the day and treat the rest as bonus. Give the likely spots time before moving. Autumn rewards covering water while the fish roam.

Set in Denver County, Colorado, this is Upper Derby Lake. Around the bank it is open valley. About 21 acres of surface, which puts the far bank inside easy sight. The closest town, Derby, is 4.7 miles away. Commerce City is 5.3 miles away, with Aurora at 6.2 miles. Others worth noting: Derby Lake (0.4 miles), Landora Lake a touch under 1.3 miles, Lake Mary (1.6 miles), Reservoir D a touch under 2.4 miles and Bluff Lake (4.3 miles). Two sets of local rules meet not far from this water.
We hold no survey for this water; read the slope of the shoreline instead. A reservoir gives you a hard edge, a shelf, and not much else. Held water runs deepest at the wall and shallows back to the inflow. Species logged across Denver County include common carp, white sucker, bluegill, green sunfish and longnose sucker. Records at this level tell you what is in the area. At Upper Derby Lake the first feature you find is worth twenty minutes.
Climate records put July near 74°F and January near 30°F. The swings are modest, so patterns change slowly. Cover comes and goes, so treat it with suspicion rather than trust. The hot months push the fishing to dawn and dusk. On Upper Derby Lake the same rules apply, with local timing.
The paperwork position is blank for this one. The car has to stay half a mile away, which shapes how much tackle you bring. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Bank access can be seasonal on ground like this. Signs go up and come down, so check on the day. The nearest alternative is Derby Lake, 0.4 miles out. Rules at Upper Derby Lake are worth checking on the day.
