to peak high flow periods, presumably accompanying snow melt entering the stream. Periods of rapid
temperature increase consistently occurred sometime between March and May, following the cessation of the
winter high-flow period. The most consistent phenomenon occurring every year in Twelvemile Creek (see
Figure 5.5) was an episode of sharp temperature decline that accompanied flow increases due to October
rainstorms. This phenomenon is likely an important cue to migratory fish, such as steelhead trout, which
commence moving upstream from the mouths of many streams along Lake Erie when the first surge of cold
water enters the lake from its tributaries.

Erie watershed, in relation to the size of each stream
