A crisp, open sky after dark, with stillness over the whole water with pressure dropping. Start the search at Porter Reservoir Number 4 along the margins and the shelf beyond them. Make the night the heart of the trip. Make the first hour count and build on it. Falling temperatures are switching fish back on.

Night
Delta County, Colorado, is where Porter Reservoir Number 4 sits. Around the bank it is pine and birch. It covers about 10 acres, so this is small water you can walk round in under an hour. Head to Cedaredge, 10 miles away, for anything you forgot. The big place round here is Boulder, 169 miles distant. There is no boundary nearby to worry about.
No depth figure appears in our records, so the bank has to tell you. The arms fish better than the open middle whenever the water is up. Built water gives depth close in, which suits a bank angler. Fish documented in Delta County include rainbow trout, white sucker, flannelmouth sucker, bluehead sucker and brown trout. What holds for the county may not hold for this water. At this water light and wind decide more than tackle does.
Between January at about 19°F and July at about 60°F, the water has a wide range to work through. Winter shuts the surface down for months. The lid usually goes in early May, which opens the strongest weeks of the year. Ice usually gives way near early May, and forms again about late November. Look to early summer and the first cool weeks of autumn. On this water that shapes the whole year.
No public source sets out the position on this bank. Nothing built is recorded close to the bank here. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Some banks are open only from a marked point. Night access is frequently treated as a separate matter. For a change of water, Porter Reservoir Number One is 0.6 miles distant. Confirm access to this water locally before you travel.
