Fish Iowa - Lakes, Ponds, and Reservoirs - Nashua Impoundment (Cedar Lake)

Fishing Forecast

Cedar Lake is an impoundment on the Cedar River in Nashua. The dam, originally built in 1916, was the site of the hydro-electric powerhouse for Cedar Valley Electric Power Plant operating until 1963 when a flood shut it down. After years of minimal operation, the dam was renovated in 1989/90 allowing the plant to generate electricity again. The lake maintains an outstanding Channel Cat fishery and is stocked annually with fingerling Walleye.(2023)

Consumption Guidelines

Iowa-Caught Fish Are Safe to Eat, In Almost All Cases

In nearly all cases, Iowa fish are safe to eat. Cleaning and/or preparing the meal causes most of the problems regarding taste or color of fish. Like all living creatures, fish are susceptible to diseases, parasites, and other naturally occurring conditions in the water. If you suspect your fish is affected by any of these conditions, do not eat it. Consider eating smaller and younger fish which usually have lower levels of contaminants than larger ones. Most contaminants accumulate in larger, older fish. For additional information, check out our resources for eating and cooking Iowa caught fish.
