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.
