Water Monitoring Data

The Watershed Monitoring and Assessment Section collects and disseminates water-related data.  All of our raw data is provided through our Iowa STORET Retrieval web application.  We also provide "data" to the public in the form of decision-making tools, like the Water Quality Index.  Choose from a subject below to explore our data.
