Look for Bull Frog Lake in the DuPage County part of Illinois. The ground round it is pine and birch. Small at around 16 acres: two anglers spread out cover most of it. Supplies mean a trip to Burr Ridge, 2.9 miles off. Beyond it, Willow Springs at 3 miles and Justice at 4 miles. A county boundary sits nearby, which can matter for local access rules.
Depth remains unrecorded, so treat the first session as a survey. Points where the flooded channel swings in are the reliable ones. Inflow corners move water, and moving water gathers fish. Records held for DuPage County cover bluegill, green sunfish and common carp. The list covers the county rather than this water alone, so treat it as a guide. Fish Bull Frog Lake where the bottom changes rather than where it looks deep.
The warm month here averages 74°F; the cold one sits at 22°F. Cold locks it up for a good stretch each year. Hard cover is dependable here; it goes around mid March. The season between ice runs from about mid March to mid December. Spring is short and heavy here; autumn is longer and steadier. Plan any trip to Bull Frog Lake around it.
There is no clear statement anywhere on who can fish it. Launch at Saganashkee Slough Boat Launch, 0.9 miles from the water. A car park sits roughly half a mile away. There is a mapped landing stage 130 yards away. You can camp 140 yards off, which suits an early start. A picnic spot sits half a mile from the bank. A toilet block sits 150 yards away. Rules for this water may differ from the county norm. Some ground is open by custom rather than by right, so tread carefully.
