DES MOINES – Iowans interested in the addendums to three DNR studies to improve water quality in Meadow Lake in Adair County; Lake Anita in Cass County and Green Valley Lake in Union County; can view a presentation on the Iowa DNR’s YouTube channel.
Meadow Lake and Lake Anita were previously listed on the state’s impaired waters list for high levels of algae and Green Valley Lake was previously listed on the state’s impaired waters list for high levels of algae, turbidity and low levels of dissolved oxygen The DNR conducted studies in 2019 for Meadow Lake and Green Valley Lake and in 2023 for Lake Anita. These studies showed how the respective problems were caused by too much phosphorus in the lake. The problems impact recreation on the lake and aquatic life.
Subsequent to the respective studies, Meadow Lake and Lake Anita were listed on the impaired waters list for turbidity issues and Green Valley Lake was listed on the impaired waters list for pH issues. The addendums explore the relationship between these new impairments of turbidity and pH and the previous studies focus on phosphorus and how they are connected. The addendums are designed to give a more complete story in relationship to listed impairments in order to better serve as a guide for local resource agencies, partners, stakeholders and residents to improve the lake.
The full documents can be downloaded on the Iowa DNR’s website at the following:
