Lake Status Summary ( Full PDF Report )
The bluegill population was sampled in spring trapnet and in fall electrofishing surveys. The current bluegill population is rated as average, with the larger fish up to 7.5 inches in length. This population is of moderate density and in average body condition. The competition with the gizzard shad has reduced the bluegill condition and growth.
The current channel catfish population is rated as excellent, with the larger fish up to 25 inches in length. This population is of high density and in good body condition. 1,500 fish at 7 inches were stocked in 2016. An annual stocking of non-vulnerable channel catfish has occurred in the recent past. These stockings have established a high density population, and the stocking can be adjusted to an every other year stocking starting in 2017.
The white and black crappie populations have been an average rating in recent years. In 2017, the crappie regulation was changed from a 9 inch minimum length limit and 10 fish daily harvest limit, to a 25 fish daily harvest limit with no more than 10 fish greater than or equal to 10 inches. The goal of the new regulation is to allow the harvest of more of the slower growing black crappie, while maintaining and promoting the population structure of crappie over 10 inches in length.
The largemouth bass population appears to be defined by a high percentage of fish from 6 to 19 inches in length with good average relative weights. In 2017, the bass regulation for Argyle Lake was changed from a 1 fish greater than or equal to 15 inches and/or 5 fish less than 12 inches daily, to a protected slot length limit from 14 to 18 inches with 3 fish daily harvest limit. The goal of the new bass regulation is to increase the density of the bass population from 14 to 18 inches. The goal of the protected slot length limit is to create a high density bass population that is composed of fish large enough to be efficient predators upon the panfish and gizzard shad population. The benefit to bass anglers will be more fish surviving past 15 inches to catch, and for the anglers who want to harvest bass will be the opportunity to still harvest fish under 14 inches. The online IFISH tournament registration and result system was started in 2015. The tournament results showed these anglers spent 336 hours in 2015 and 576 hours in 2016 on Argyle Lake. They reported 14 legal fish in 2015 for .04 fish per angler hour. They reported 45 legal fish in 2016 for .08 fish per angler hour.
A total of 12 muskie were sampled by the spring trapnet survey in 2016. These fish ranged from 18 to 41 inches long. The body condition of these fish was low. A low density of quality size muskie are present. In 2016, 93 muskie at 10.75 inches were stocked. Annual stocking is now scheduled to maintain a low density of healthy muskie. In 2017, the muskie harvest regulation was changed from the statewide 1 fish daily harvest at a 36 inch minimum size, to a 42 inch minimum and 1 fish per day harvest limit. The goal of the new regulation is to protect the fish for at least 1 more year from angler harvest.
In 2016, 6,640 rainbow trout were stocked on 10/3/2016. These fish are annually stocked for the catchable trout program. The fall electrofishing survey collected 52 of these fish and they ranged from 9 to 14 inches in length.
The current redear population is rated as average with the larger fish up to 9.8 inches in length. This population is of very low density and in very good body condition.
The saugeye population was sampled by spring trapnet and fall electrofishing surveys. The current saugeye population is rated as good with the larger fish up to 27 inches in length. This population is of moderate density and in average body condition. In 2016, 11,935 fish at 2 inches long were stocked.

Argyle Lake was constructed in 1949 with funding from the licensed anglers of the state of Illinois.
History and Status of the Sport Fishery: The lake and its sport fishery are evaluated annually by spring trapnetting and fall electrofishing surveys. These surveys direct the fish stockings, fishing regulations and vegetation treatments.
