Arrived at the Rio Don Diego after breakfast, and found a dirt path next to a bridge, leading off Hwy 90, into a pueblo (which is just a wide spot in the road). The dusty path was just large enough for the little rent-a-car to fit thru, passing very close to small casa’s , tienda’s and a pool hall, and we ended up in a clearing on the rivers edge.
The river was about 50 meters wide, and has a fairly strong current, so after a bit of wading, and struggling against the moving cool, water (especially where it was more than a few feet deep). We decided to hire a boat. I explained him my interest in riverine fish, so as we motored down el rio, and he skirted the shoreline all the way from the pueblo to the sea and back again, over half an hour each way.
We stopped at a rickety shack for a rest, on the shore of the Caribbean, where I compared the river water temp to the sea.
The water in the river was clear as glass, and the substrate much like pool filter sand, giving the appearance of a desert except for right along the waters edge. There, fallen trees, occasional water lilies, and lush overhanging vegetation provided the only cover for fish trying to escape the many predatory birds.
