A clear night sky over the water, with the water lying quiet and pressure leaking away. Twin Valley Lake should fish best around shallow cover and weed edges today. The productive run goes afternoon into evening. Start on the obvious water and expand from there. Fish follow the bait in autumn, so find one to find the other.

Twin Valley Lake is set in Iowa County, Wisconsin. The surface lies 909 feet up. Around 136 acres of surface means several distinct areas to work. Some 3.9 miles of bank gives room to move when the wind turns. Nearest town is Dodgeville, 4.8 miles off. Madison sits 35 miles out, and it is the nearest city worth the name. No county line comes close, which keeps the paperwork simple.
Recorded soundings reach about 32 feet at the deepest point. Built water gives depth close in, which suits a bank angler. Look for where the old bank line still shows under the surface. Survey and observation records for Iowa County include brown trout, rainbow trout, bluegill and common carp. Read it as a county summary, not a water-by-water list. Read Twin Valley Lake before you fish it and the day goes better.
Averages here run 71°F at the top of summer and 15°F at the bottom of winter. The year splits cleanly: hard water, then open water. The open season starts with the thaw, near enough early April. On the long-run averages the water opens up around early April and starts locking again about early December. Fish feed hardest at the start and the close of the open season. That is the shape of the year on Twin Valley Lake.
Nothing we hold confirms whether access is permitted. There is a slipway at Twin Valley Lake Boat Landing, roughly half a mile off. The nearest mapped parking is half a mile away, so the last stretch is on foot. Overnight stays are possible half a mile away. Facilities include toilets around half a mile from here. Some banks are open only from a marked point. Where parking is tight, arriving early solves most problems. Cox Hollow Lake 9, 1.4 miles away, makes the obvious fallback. Treat access at Twin Valley Lake as something to verify.
