April 1, 2014 to November 30, 2016

Funding Source(s):

Iowa Department of Natural Resources (IDNR)


Goals and Objectives:

To provide the Iowa Department of Natural Resources with a diagnostic and feasibility study of Silver Lake, Palo Alto County, Iowa for planning and implementing lake and watershed improvement efforts.



Silver Lake monitoring activities for lake, tributary, and outfall locations were completed in January 2016. We have completed all physical, chemical, and biological analyses of water samples collected for the project. We are currently analyzing the dataset for the diagnostic study and identifying restoration alternatives for improvement of lake water quality. We hosted the second local steering committee meeting in March 2016 to discuss findings from the diagnostic study.


Future Plans:

We will submit the final diagnostic study report and recommendations for the feasibility study to Iowa DNR by September 30, 2016. With the help of Iowa DNR, we will coordinate a public meeting and two local steering committee meetings during Summer through Autumn 2016 to present findings from this study to the public and to develop effective restoration strategies with community leaders, respectively.
