Fish Status



Black crappie numbers continue to improve but remain low. Growth rates and body condition are good. In spite of the relatively low numbers, some anglers successfully target crappie each spring and consistently catch limits. Best fishing is around tree tops in the warm arm in early spring. Site Regulation: White, Black or Hybrid Crappie: 10 fish daily limit; 10" minimum length limit.



The bluegill population is in extremely poor condition. High summer temperatures (Newton Lake has very little thermal refuge) and a dense population of shad contribute to poor reproduction and slow growth. This lake is not recommended for bluegill.



Natural reproduction is tremendous in this cooling lake. More recently, the growth rate and size structure of the population has improved. Although still dominated by smaller fish, the population contains an adequate number of large fish to provide a good quality fishery. For 2017, the majority of the catch will be comprised of fish 1 - 4 pounds, with some larger fish up to 5.5 lbs. These fish are in excellent body condition and because of their abundance, there is no daily creel or size limit. Bank fishing opportunities have been expanded to include the shoreline bordering all non-restricted areas of the lake. For boat anglers, drift fishing the flats in both the warm and cool arms of the lake can be productive year round.



The size structure of the bass population in Newton Lake declined last year. The percentage of bass greater than 18" fell by just over 60%, and comprised only 7% of the total population. At the same time the catch per effort skyrocketed to an incredible 251 bass per hour! This lake continues to support a very good bass population, however, the fishery appears to be on the verge of change. The amount of hot water discharged into the lake has declined significantly, and this has resulted in a reduced growing season. In short, it is transitioning from a cooling lake to an ambient lake. In the near term, recruitment continues to be good and, with body condition and growth rates above average, the fishery should remain stable for the near future. For 2017, Newton Lake should still provide excellent angling opportunities. Anglers can expect to catch large numbers of fish from 15” – 20” in length ranging from 2 – 6 pounds. The majority of bass exceeding the 18” minimum will weigh between 3.5 – 7 pounds. Site Regulation: 3 fish daily limit; 18" minimum length limit.


Very Good

Angling opportunities for this species look good for the coming year. The catch rate in 2016 increased significantly to just above the historic average. The population continues to exhibit excellent growth rates and body condition. Two large year classes of fish will contribute to the fishery in 2017. Most of these fish will range from 12” – 15” with larger fish up to 17” common. Fish the main lake points or troll the flats to locate fish and then cast to schools. Site Regulation: Unlimited except no more than 3 fish over 17".
