MN DNR Rosgen II Training Course

This is a single source posting notification; there are no solicitation documents to download. The Minnesota Department of Natural Resources (DNR) has adopted the use of the Rosgen Stream Classification system, the Natural Channel Design approach to stream restoration, and the Watershed Assessment for River Stability and Sediment Supply (WARSSS) watershed assessment methodology and intends to purchase 12 training spots for the River Morphology & Applications course ; training students to conduct a geomorphic characterization and delineate stream types using the stream classification method. The class includes a combination of lecture and field sessions providing practical experience in the following subjects and activities:

• Integrating fluvial geomorphology concepts with problem-solving techniques
• Learning and mapping fluvial landscapes and valley types
• Pre-mapping landscapes and stream types on aerial photos and topographic maps
• Field validation of the bankfull stage at a USGS gage station
• Regional curve development
• Field methods to properly measure morphological variables and develop dimensionless ratios for assessment and design
• Stream succession and the central tendency of rivers
• Reference reach selection and applications
• Management applications using stream types

This purchase has been deemed a single source given the MN DNR staff that have been selected to attend are those that work directly with Applied Stream Geomorphology/stream restorations/watershed restorations and have permitting authority on problems impacting steam systems and river restoration and enhancement projects. If anyone has concerns regarding this single source request, you must contact Valerie Fellows via email at valerie.fellows@state.mn.us no later than April 22, 2026 at 2:00 PM Central Time.
