Upper Stump Lake is part of the Stump Lake complex located in Illinois, just north of Pere Marquette State Park. The lake is accessible via a boat ramp at the Stump Lake Fish and Wildlife Area, which provides access to Upper Stump, Flat, Long, and Fowler lakes. This area is characterized by backwaters and slow-moving water, typical of the lower Illinois River region.

The lake complex offers excellent fishing opportunities for bluegill, crappie, and bullhead. Paddlers can expect to encounter various fish species and potentially observe wildlife in the surrounding area. The water is generally calm, making it suitable for paddlers of different skill levels.

When planning a trip to Upper Stump Lake, be aware that waterfowl management areas may be closed to access during certain times, as posted at the site. It's advisable to check with the Mississippi River Area office for specific restrictions and up-to-date information on access.

The surrounding landscape includes backwater lakes and side channels, providing a diverse paddling environment. The area between Grafton and Nutwood, where Upper Stump Lake is located, is known for its good sunfish and bass fishing, which may interest anglers who combine paddling with fishing.

While specific details about Upper Stump Lake's size and unique features are limited, it is part of a larger ecosystem influenced by the Illinois River and its tributaries. Paddlers should be prepared for potential encounters with various fish species, including Asian carp, which have become prevalent in the lower Illinois River system.

For safety and regulations, paddlers should be aware of any fish consumption advisories in the area, particularly for larger catfish, due to historical PCB contamination. Always check current advisories before consuming any fish caught in the lake.
