Lake Status Summary ( Full PDF Report )
Bluegill were less abundant in 2015 than in the previous year, but the quality of those fish increased, as evidenced by the fact that 60% were larger than 6 inches and 37% exceeded 7 inches. Bluegill were also in good condition.
Channel catfish are generally not a large component of the annual electrofishing sample, and 2015 was no exception. In fact, only six were collected, which represented an increase compared to the previous year. These fish were in excellent condition and ranged from 21 to 25 inches in length. Annual channel catfish stockings help support a fishery which is very popular with the angling public. Site Regulation: 6 per day creel.
Black crappie were collected in 2015 at a rate that was somewhat less than the previous year. Black crappie ranged in size from 3 to 14 inches; 55% were larger than 8 inches and 25% exceeded 10 inches in length. White crappie were similar to black crappie in abundance. The size range of these fish (3 to 14 inches) was also similar to that of black crappie, as were other statistics — 50% larger than 8 inches and 19% over 10 inches in length. Crappie weighing more than 2 pounds are regularly reported by Mermet Lake anglers. Site Regulation: 25 per day creel.
Largemouth bass were collected at a slightly substandard rate in fall 2015, but 69% were larger than 12 inches. 62% were also longer than the 14 inch minimum size limit, and 14% exceeded 16 inches in length (the new length limit, which will go into effect April 1, 2016). Bass condition remained excellent. Site Regulation effective 4/1/16: 16” limit and 3 per day creel.
Smaller numbers of redear were included in the 2015 sample than bluegill, but these fish ranged from 8.5 to 11.5 inches in length and were in excellent condition.
Location: Mermet Lake is a shallow, 452-acre, IDNR-owned impoundment located in Massac County approximately 10 miles north of Metropolis.
Description: Mermet was originally built as a water supply for flooding adjacent wetland compartments for waterfowl hunting, but sport fish flourished when stocked, and the lake has been managed for fishing for approximately 50 years. Curlyleaf pondweed, an exotic aquatic plant, invaded Mermet in 1999, and has caused occasional summer fish kills since then, but annual herbicide treatments have generally been successful at controlling the impacts of this plant in recent years, allowing the sport fish population to slowly recover.
Additional Lake Information: The outboard motor limit is 10 hp, but boats with larger outboards are allowed to operate at no-wake speed. Mermet Lake is closed to fishing during the duck season.
