Stream flow is the key factor as to how quickly coho salmon are able to reach Tenmile Lake. During some dry fall months, I have observed coho salmon swimming into the fish trap where Eel Creek, a Tenmile Creek tributary, leaves the lake as late as the first week in March. During normal years, there is seldom enough water to get decent numbers of cohos into Tenmile Lakes, where they are legal angling fare, until at least late October. Of course, everything depends upon creek levels. One good thing is that the sand bar where Eel Creek enters Tenmile Creek no longer blocks fish passage up Tenmile Creek.
