Look at all these fish on redds... they are hard to see and avoid when you are at the water level. I took this yesterday on a famous river in Alberta. Those grasses along the waters edge are about 20 inches tall (I picked them and they are just about the length of 2 sheets of paper). Compare that to the couple of large fish in the water (dark shape above boulder)... WOW.

These are other less obvious shots from earlier...
