The Fox Waterway Agency currently reports the Chain O’Lakes waterway status as OPEN.
Fox Waterway Agency
According to the most recent Fox River Status Update (September 25, 2025), no rain is forecasted for the lakes over the next 7 days, and inflows are expected to remain near current levels. – Illinois Department of Natural Resources
The Stratton Lock & Dam (which helps regulate lake/river levels) remains in operation; its opening hours are extended through September, per IDNR’s schedule (8 a.m. to midnight).
Gate operations at the Stratton Dam are guided by inflow, lake stage, and forecasts; when flows exceed certain thresholds (e.g. ~1,800 cfs), flood operations may be triggered.
Thus, for now, conditions are favorable for boating and navigation across the Chain, with no known closures or restrictions.
Water Levels & Flows
Fox Lake, the upstream pool, is currently projected to be between 4.00 and 4.15 feet in stage (gage height) for the near term.
Inflows (the water coming into the system) are estimated at ~698 cubic feet per second (cfs), with outflows around 746 cfs.
Since rainfall is minimal in the forecast, and inflows are expected to stay steady, water levels are likely to remain relatively stable over the coming days.
The Chain O’Lakes & Fox River water level graphs (on the Fox Waterway Agency site) reflect current levels across various gauge stations (e.g. Fox Lake near Lake Villa, Fox River at Johnsburg, tailwater near McHenry). – Fox Waterway Agency
Independent monitoring via FoxChain.uslakes.info also tracks daily levels and historical charts, which show that the lakes are not unusually high or low at present.
Fox Chain Lake
In short: levels are moderate, steady, and within expected operational ranges. No extreme flooding or drought drawdown is imminent.
Water Temperature & Clarity
Real-time fishing and lake data sites (e.g. LakeMonster) report a current water temperature of approximately 61 °F for the Fox Chain O’Lakes.

While I did not find a robust, system-wide recent clarity (turbidity) reading in the public reports, typical fall conditions suggest improved clarity in deeper zones, with possible mild turbidity near shorelines or in inflow zones.
The presence of zebra mussels in the system (noted in the I Fish Illinois profile) can enhance water clarity by filtering, but also affect ecosystems in other ways.

For anglers and swimmers, the cooler temperature signals that seasonal turnover may be underway or approaching in parts of the system, so stratification and mixing may affect oxygen and nutrient profiles.
Ecological & Fisheries Notes
The Chain is actively stocked with species such as walleye, largemouth bass, and muskellunge. – ifishillinois.org
Fish populations in the Chain are considered healthy; for example, the I Fish Illinois profile identifies the walleye fishery as “Very Good.” – ifishillinois.org
Because of zebra mussel presence, ecological dynamics (nutrient cycling, clarity, benthic habitat) are influenced. – ifishillinois.org
Anglers should watch for shifts in fish behavior as water cools: many game fish may move deeper or seek thermally stable zones.
Considerations & Tips for Boaters, Anglers, Residents
Watch levels and gate operations. Because lake/river levels are managed actively (via Stratton Dam), conditions can shift if rainfall or upstream inflow changes.
Be cautious near shorelines and shallow zones. Even though levels are stable now, autumn drawdown is possible later, and shallow areas can become hazards.
Use appropriate gear in cooler water. With temps near 61 °F, dress for potential chill, and use depth-aware techniques when fishing (fish may be deeper).
Monitor clarity and vegetation. Late season aquatic vegetation and decaying biomass can affect clarity and snag risk.
Check for advisories. Local agencies or lake associations may issue warnings (e.g. regarding water quality, fish consumption) that don’t always appear in broad reports.
The Fox Chain O’Lakes marinas are buzzing with activity this season. Boaters are making the most of the mild fall weather, and slips across the Chain are still active with weekend traffic.
Water Levels & Conditions
Water levels remain stable, with depths holding steady in most harbors and channels. Navigation is smooth, though boaters should continue to watch for shallow spots near the shoreline and sandbars, especially in the back bays.
Fuel & Services
Fuel docks are fully stocked, and most marinas are still offering full-service amenities, including pump-outs, mechanical support, and general boating supplies. Some smaller service docks have begun transitioning into reduced hours as the season winds down, so it’s best to call ahead before making a stop.
Seasonal Updates
Slip Rentals: Many marinas are beginning to take reservations for next season. If you’re looking for a prime spot on popular lakes like Pistakee, Fox, or Lake Marie, early booking is recommended.
Winterization: Mechanics are already scheduling winterization services. Boaters planning to keep their vessels in top condition should secure appointments soon, as schedules will fill quickly.
Events: A few marinas are planning small community events and live music nights before closing out their summer season—check with your local marina for details.
Overall Outlook
The marinas on the Fox Chain O’Lakes continue to provide a welcoming hub for boaters, anglers, and families alike. Whether you’re fueling up, stopping in for supplies, or looking to reserve a slip for 2026, the Chain’s marinas remain the lifeblood of lake activity.
Fishing the Fox Chain O’Lakes can be an incredible experience, but it’s no secret that this vast waterway system can sometimes be challenging to navigate.

Despite their reputation as a non-game fish, Freshwater Drum are actually noted fighters when hooked and are known to be rather tasty when eaten. Fishing tackle should target the bottoms of lakes and rivers where the fish actively feed.
