Michigan Stream Team. In 2002, staff from MDEQ, MDNR, USGS and NRCS met to discuss ways to share resources and to develop common methods for collecting stream morphology data
Original intent of the stream team was to develop a common method of taking stream measurements among agencies in Michigan taking such measurements in order to assemble a data base of the information and create regional reference curves for the entire state.
A reference reach is a channel segment that is stable, neither aggrading nor degrading, and of the same morphological type as the channel being assessed. The reference reach should also have a valley slope similar to that of the assessment reach.
The reference reach is used as the standard against which the assessment reach is being judged. To account for differences in drainage area and discharge between a reference site and an assessment site, data on channel characteristics (dimension, pattern, and profile) in the form of dimensionless ratios are developed for the reference reach.
Flow that maintains the pattern, dimension and profile of a stream channel.

The Stream Team has developed a proposal to take the necessary measurements and develop regional reference curves over a 3 year period, beginning with 2006 Field season. Funding is currently being determined.
