Sun Valley Lake near Mount Ayr: Fishing Spots, Seasons and Access

• Overview

  Sun Valley Lake is listed under Ringgold County, Iowa. The surface lies 1,132 feet up. At 398 acres this is proper open water rather than a pond. The perimeter runs near 7.2 miles, so plan the walk before you start. For supplies, Mount Ayr is 13 miles out. Des Moines is the closest city, 57 miles away. A county boundary sits nearby, which can matter for local access rules.

• Where to Fish on Sun Valley Lake

  Depth is not on record here, which means reading the ground instead. Draw-down through summer strips the margins, so follow the water out. Built water gives depth close in, which suits a bank angler. Records held for Ringgold County cover brown trout, white sucker, channel catfish and rainbow trout. What holds for the county may not hold for this water. On Sun Valley Lake the quiet end is the one worth the extra effort.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 75°F, while January sits near 21°F. The year splits cleanly: hard water, then open water. The lid usually sets by midwinter and gives way around mid March. On average, mid March opens the water and mid December closes it again. Reckon on open water from spring through to late autumn, with May and June the strongest. Sun Valley Lake runs to that rhythm year in and year out.

• Tackle & Baits

  The access position is unclear from public sources. The nearest mapped parking is half a mile away, so the last stretch is on foot. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Where the road in crosses private land, ask first. A polite question at the farm gate opens more banks than anything else. Failing this one, try Loch Ayr, 11 miles away. Confirm access to Sun Valley Lake locally before you travel.
