A clean, cloudless night over the water, with almost no wind to speak of and a falling glass. Give inflow corners and shaded margins the first hour at Round Lake. Block out the hours from night into morning. Cover water early, then settle where the signs are. The autumn feed-up is on; baitfish areas are the key.

Round Lake lies within the bounds of Dubuque County, Iowa. It sits at 614 feet above sea level. The water measures roughly 4 acres, so nothing here is far from anything else. It is low-lying compared with other Iowa water we list. East Dubuque sits 3.2 miles from here and is the nearest stop. Further out sit Dubuque (4.4 miles) and Asbury (8.6 miles). The boundary is near enough that local access rules are worth double-checking.
Depth is unmeasured here, so let the shoreline guide you. Weed, then depth: that is the order to fish a water of this kind. Read the surface for the wind lane, then fish the edge of it. Open biodiversity records for Dubuque County list bluegill, johnny darter and largemouth bass. County data is a starting point rather than a guarantee. Read Round Lake for ten minutes before the first cast goes out.
Climate records put July near 74°F and January near 18°F. Cold locks it up for a good stretch each year. Hard cover is dependable here; it goes around late March. Climate figures give an open season running late March to mid December. Right after break-up, and again as the nights sharpen, is when to go. Time your trip to Round Lake by conditions rather than dates.
Access status is simply unknown for this water. We find no slipway, car park or made path within a short radius, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Rules differ from one water to the next round here. Some stretches are reserved and marked as such on the ground. Failing this one, try Galena Lake, 14 miles away. For Round Lake in particular, ask before you travel.
