HARLAN – Iowans interested in the results of a DNR study to improve water quality in Prairie Rose Lake in Shelby County can view a presentation on the Iowa DNR’s YouTube channel.

Prairie Rose Lake is on the state’s list of impaired waters for high levels of algae and turbidity. The current study, or DNR water quality improvement plan, shows how these problems are caused by too much phosphorus in the lake. The problems impact recreation on the lake and aquatic life.

The plan explores the amounts and sources of phosphorus entering the lake and offers potential solutions to reduce those levels and work toward fixing the problem. The document is designed as a guide for local resource agencies, partners, stakeholders and residents to improve the lake. 

The presentation is available now at through Sept. 8. The full document can be downloaded on the Iowa DNR’s website at the following:

Public comments on the plan must be submitted by Sep. 8 to the following:

Mail:  Jeff Berckes, care of Iowa DNR, Wallace State Office Building, 502 E. Ninth St. Des Moines, Iowa 50319

After gathering Iowans’ comments, the DNR will forward the final plan, also called by its technical name of Total Maximum Daily Load (TMDL), to the U.S. Environmental Protection Agency for approval.
