– The Iowa Department of Natural Resources has temporarily suspended
its regular trout stocking on five streams due to stream temperatures
ranging between 70 degrees and the low 80s.
The
DNR is temporarily not stocking trout at Bohemian Creek, in Winneshiek
County, Turtle Creek and Spring Creek, in Mitchell County, Twin Bridges,
in Delaware County, and Upper Swiss Valley, in Dubuque County. Streams
will be evaluated weekly to determine if the suspension will be lifted.
“We
need to have either the weather cool off or get some precipitation to
increase stream flows which should help stream temperatures to
decrease,” said Brian Malaise, hatchery manager at the Decorah trout
hatchery.
The fish coming from the trout hatcheries are in 50 to 56 degree water.
“The
trout stocked earlier in the year in those streams have become
acclimated to the warmer water and can find springs with cooler
temperatures, but trout being taken from 50 degree water at the hatchery
cannot be stocked in 70 to 80 degree water without some mortality,”
Malaise said.
