Surface water sampling on the main stem of the Redwood River and two of its tributaries (Clear Creek and Three Mile Creek) continue each growing season (May through September). Monitoring at each of the sites will extend throughout the implementation phase of the Redwood River Clean Water Partnership Grant. Samples are collected during two year storm events on a four hour interval. Grab samples are taken from Lake Redwood at monthly intervals. Base flow samples are monthly throughout the growing season. Data collected at these stations is analyzed and reviewed to identify trends. Water quality data plays an important role in assessing watershed improvements.

Other monitoring sites: In response to flooding in the early 1990s, grant funds were obtained to expand the stream gaging network in the state. A number of organizations (Minnesota Division of Emergency Management, Minnesota Department of Natural Resources, National Weather Service, and the United States Geological Service) are working together to make the stations operational. Gages were placed according to where more specific data were needed, and community support was evident.
In 1999, there were thirty-eight new stream gages put in place around the state. One is still in place in the Cottonwood River Watershed, this gage is located on the river near Springfield. Another was placed in the Redwood River Watershed, near Marshall.
