The bluegill population improved slightly for the second year in a row. The percentage of bluegill greater than 8” was the highest in more than two decades and body condition remained good. If this positive trend continues, it should eventually result in a significant improvement in the size structure of the population. Fishing in the coming year should be fair with most keepers 6” – 8” in length and 0.25 – 0.33 lbs.
Catfish numbers remain low in East Fork Lake, but the average size of the fish is exceptional. Most fish will range from 3 – 10 pounds with larger fish up to 15 pounds common. Body condition of these fish is excellent. This lake provides some good bank fishing opportunities. Drift fishing the main lake is also very productive.
The size structure of the bass population improved slightly for the second consecutive year. The catch per effort fell, but, the percentage of fish over 15” in length increased significantly. Data from the annual population survey show 31% of the population exceeds the 15” minimum length limit. The number of fish just below the 15" minimum length limit remains high and, if mortality rates can be reduced for bass > 15”, the large number of smaller bass (12” – 14”) should further improve the size structure of the fishery in the coming year. The body condition for all sizes of bass has also improved to well above the minimum standard. Bass fishing should be fair to good in 2016 with most keeper fish ranging from 15” – 18” in length and weighing between 1.6 – 3.5 pounds.
The size structure and size of the walleye population remains stable. Four year classes were collected in this year’s survey, but the catch rate of just over 5 per hour remains below average. While the number of walleye has declined over the last 5 years, a significant percentage of the remaining population is comprised of older larger fish, with many in the 3 – 6 lbs. range.
The white crappie population showed some improvement in the past year, but remains below optimal. The population is still dominated by a strong year class of 8” – 9.5” fish. There are also a large number of 6” – 8” fish that are growing rapidly and should contribute to the creel by late 2016. All sizes of fish were in good condition. The percentage of fish over 10” in length improved over the past year to 20%, up 9 percent from the previous year and, if growth rates remain good for the large year class of smaller fish the size structure of the population should improve further in the coming year. For the spring of 2016, most keeper fish will range from 9” – 10.5” in length and weigh from 0.5 – 0.7 lbs with a few larger fish up to 14”.
