Ohio Stream Assessment Method Review

This summer MAD, in partnership with Ecosystem Planning & Restoration (EPR), and the Ohio EPA, has been working on surveying reference quality streams across Ohio’s six major ecoregions. The team has been evaluating metrics such as bank erosion, riffle and pool lengths and depths, substrate size, stream slope, floodplain connectivity and riparian vegetation quality to characterize key geomorphological and habitat features of the streams. This data in Ohio is being collected for the purpose of verifying regional curves as well as establishing and verifying reference curves in Ohio and applied to the Ohio Stream Assessment Method (OSAM). OSAM is intended to be used as the states’ updated stream functionality assessment as part of the effort for calculating mitigation credits and debits. Refinement of the OSAM […]

More than that though, we get to use this information to help clients determine what they have and what they can do with their properties. Oftentimes clients need this information for a baseline survey if the property is being put under easement or covenant. Other times, land managers wan to know where opportunities lie for restoration or where to avoid disturbance if rare species […]
