I have a ditch on our property which fills up with water from Oct. to May and then it dries out.
Every year I catch about 3000 coho fry that become landlocked and put them back into the river.
In the mix of fry which varies from smolts to a lot of fry that are about 1-11/2 inches long.
My question is,are these small fry likely born in the ditch or have they migrated from the river?
The ditch is a windy 500 yards long before it enters the river.
Have never seen any salmon activity in the ditch although it's hard to see because of water clour.
