Crystal Lake suffered a summer fish kill in July 2015 due to low dissolved oxygen. This event will set the fishery back. Crappie and bluegill survived the kill, but size and densities have declined. Aggressive predator stockings (walleye and largemouth bass) were done in the fall of 2015 as well as a stocking of bluegill. In 2016, predator stockings of northern pike and largemouth bass will take place. This fishery will return, but in the short term anglers will experience reduced success.(2016)

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

The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed. Some limitations may apply for young children and pregnant women. Here’s a Fish Consumption Fact Sheet from the Iowa DNR and the Iowa Dept. of Public Health for more information. Here is a list of current fish consumption advisories for Iowa lakes and rivers.
