Glare on the water under a clear sky, with an easy breeze from the SSE with the glass slipping lower. Expect most activity at Upper Brennan Lake around inflow corners and shaded margins. If you pick one session, make it the evening. Work fewer spots, but work them properly. Cooling water has fish active and on the move.

Upper Brennan Lake stands in Clare County, Michigan. It sits at 906 feet above sea level. At roughly 4 acres, the whole thing is within casting reach of a single walk. On size it sits at the modest end of our Clare County list. Harrison is the closest town at 5.4 miles. The big place round here is Grand Rapids, 85 miles distant. No boundary runs near, so the county rules hold throughout.
Nothing we hold settles how deep this runs. Read the surface for the wind lane, then fish the edge of it. Weed, then depth: that is the order to fish a water of this kind. Open biodiversity records for Clare County list bluegill, largemouth bass and pink salmon. County records show the wider picture rather than this one place. At Upper Brennan Lake light and wind decide more than tackle does.
Seasonal averages run from 19°F in January up to 69°F in July. The year runs cold to warm and back, with clear transitions. Count the season from break-up, usually early April. From about early April to around mid December, expect open water on the long-run figures. Look to early summer and the first cool weeks of autumn. Upper Brennan Lake runs to that rhythm year in and year out.
Whether the bank is open is not something our records settle. The map shows no ramp or car park nearby, so this is a walk-in water. A small crankbait along the drop and a worm in the thick stuff cover the bass. Rules differ from one water to the next round here. Where tickets apply, they are sold in the nearest town rather than on the bank. Norway Lake sits 0.4 miles off and takes the overflow. Treat access at Upper Brennan Lake as something to verify.
