Not long to go until the spring now. I usually kick off my season on the Usk around mid-April although some folks up in Scotland and Wales start as early as mid March.....
Mid April is a time of transition. It is the time of the season when fishing expeditions, previously inspired by hope, become fishing expeditions radiating with the strong sense of rod-flexing anticipation. Combine this with a yearning to brush off the last winter cobwebs and you can see what drives me on my annual spring pilgrimage to the magical Usk valley.
A critical component of successful Olive fishing is to be highly tuned in to exactly what is going on above and below the water. Being aware of the various stages of Baetis rhodani is paramount as each individual stage will become a trout target as the hatch progresses. Like other members of the Ephemoptera order (mayflies) the life cycle of Baetis rhodani consists of; 1) egg, 2) agile darter nymph (various instars), 3) emerging nymph, 4) sexually immature dun (sub-imago) and 5) mature dun (imago). The astute fly fisherman will keep track of the hatch as it unfolds and the corresponding trout activity, changing tactics accordingly. Hawk-like observation, rapid changes of tactics, adaptability and quick thinking provide the key to successful spring Olive fishing.

As soon as flotillas of LDO duns start to sail downstream it is time to start scanning the water for any signs of activity in the plethora of gutters, runs and riffles, so characteristic of the upper river. Look for a nice lengthy run or pool below a long bumpy riffle. Remember, riffles are the nymph factory of any freestone river due, in part, to the increased oxygen concentration and the stable structure of the river bed which provides an excellent habitat for nymphs. When searching for productive water, try to avoid the runs and pools directly below waterfalls because the plunging water swallows up any adult duns drifting downstream reducing the density of flies perched enticingly on the surface.
So if you are wondering how to satisfy your springtime urge to be on the water then why not visit the Usk valley to see the olive spring for yourself?
