Type of channel configuration

modified - Modified waterways are natural waterways that have been straightened, usually as a consequence of diversion, dredging or diking, and have not reestablished a natural meander pattern.

natural - Natural waterways are naturally occurring water bearing features, typically with headwaters, that have not been significantly altered from their historical meandering flow path or floodplain in any manner or, if historically altered, have reestablished a meandering course passively or through active restoration

artificial - artificial

Extent of channel modification

low (5 - 25% affected) - low (5 - 25% affected): Definition of code value [low (5 - 25% affected)] in CVD extent_of_channel_modification

majority (50 to 75% affected) - majority (50 to 75% affected): Definition of code value [majority (50 to 75% affected)] in CVD extent_of_channel_modification

mostly or all (75 to 100%) - mostly or all (75 to 100%): Definition of code value [mostly or all (75 to 100%)] in CVD extent_of_channel_modification

none or only trace (LT 5%) - none or only trace (LT 5%): Definition of code value [none or only trace (LT 5%)] in CVD extent_of_channel_modification

Waterway classification

Waterway classification: low, moderate, or high plus natural, modified, or artificial, or else unknown

Decision tree question (for making classification determination)

0

1 - Is there credible knowledge of fish use (e.g.,density or population estimates, fish removal counts, or visual counts by a qualified fish biologist during mid- to late-summer low-flow period? If yes, does that knowledge/information definitively indicate either high or low/no use?

2 - If no credible salmonid use information is available, or if such information is ambiguous or may be unreliable, is there a total fish passage barrier identified in an existing GIS database or through other credible local information? If a total barrier is present, then the use of the waterway is classified as “low.”

3 - Is there known to be summer flow, a spring present, or is the channel a side channel to a mainstem river?

4 - If flows are unknown or uncertain, is the contributing (upstream) watershed area sufficient to generate summer flow?

5 - Is there a geomorphic feature present that indicates seepage, or is there a backwatering effect causing standing water and that is also connected to a perennial stream?
