The Iowa Department of Natural Resources says heavy rainfall Chickasaw and Bremer counties has caused a 60 foot by 40 foot section of the dike on Martens Lake on the Sweet Marsh Wildlife Management Area northeast of Tripoli to fail.
Wildlife biologist, Jason Auel says the Wapsipinicon River and Plum Creek got a lot of rain.
A 60 foot by 40 foot section of the dike washed out on July 23rd and that caused water to be lost from the 255 acre lake.
While it probably won’t have a major impact on wildlife in the lake, he says has impacted boat ramps and access to the popular spot for fishing.
He says the boating does tend to drop off near the end of July, but they are also getting close to the time when people start scouting out spots for duck season. He is not sure yet if the washout impacted fish.
Auel says they are trying to analyze everything to determine how to handle the problem with the dike and other damage.
Auel says they flooding may also have done some damage to the Aldo Leopold recreation area along the Wapsipinicon east of Readlyn.
Auel says they will try to assess that damage once they are safely able to do so.
