WebIFIM studies begin with a review of the history of a river regarding fish presence and their life histories. Field studies are conducted at selected locations where depth and velocity measurements are made, as well as other habitat conditions. The field data is used in the models to develop values Web• An IFIM study is used to address a “problem”; we do not know that there is a problem, so why should we move ahead with an IFIM? o Study will be used to address a process not a problem and will not be used to make a decision on whether an instream flow program should be implemented.
