River Fly Fishing & Casting
River fly fishing starts off on opening day at the beginning of August in the lowlands around Cressy. In mild conditions there is always a chance of a fish on the dry, especially in the smaller streams.
Other well known waters around Cressy, such as Brumbys Creek, fish will be collecting snail and depending on water levels, there can be some good tailing and mooching activity.
In years where we have floods the Macquarie River has many backwaters and ditches where the trout can be found patrolling, collecting worms and grubs. A Wigram’s Robin and a fur fly are a couple of favourite in sizes 12 – 8.
Toward the end of August and early September the first stone fly are hatching on Brumbys Creek. Into September and October mayfly activity gets into full swing on many of the streams in the north of Tasmania, such as Brumbys Creek, Macquarie River, Lake River and St Patrick’s to name a few favourites.
On the cooler days snails, scud, caddis patterns suspended under a dry can work quite well.
The well known mayfly of the brown dun emergers in overcast, drizzly conditions as water levels recede on the Macquarie. They return as the famous Red Spinner to lay their eggs during the calmer, warmer days.
Various other mayfly species of smaller sizes such as the baetids and caenids are hatching on the lowland rivers before the real summer heat settles in. Of course rainfall and cooler conditions towards summer can prolong these hatches. By this time on a number of the warm days, especially from October onwards, beetle falls can be an occasional to regular occurrence.
Through the hottest periods, as far as the rivers are concerned, time is best spent looking for cool flows through the Brumbys Creek tailrace, or St Patrick’s River with its generous bank-side vegetation providing shade over riffle along with more consistent terrestrial insects such as grasshoppers and beetles.
As the season begins to cool off a little many good days of dry fly activity with trout sipping down ants and a resurgence of mayfly into March and April rounds the season off nicely.
Fly casting – rivers
Fly casting nurtured in the river environment often leads to the greatest skills, especially for tight, accurate casts.
Casting on the lawn and on open, slow flowing water is a good place to get the feel for a rod and how to get the line to do what you want.
The effects of wind is another challenge to be dealt with, on how it affects the airborne line during the cast and the presentation.
Current strength, direction on a stream or river determines how the fly and the line behave.
Obstacles, trees, floating debris, long grasses, fences, overhanging branches.
Stream craft – rivers
Bank-side and aquatic vegetation, geography, geology are pretty much fixed factors. The climate, water level, temperature, rate of flow are in constant change, which in turn alters things such as dissolved oxygen level, life cycle and abundance of various species of creatures within the habitat.
I learned at the beginning of my fly fishing journey that to stop on arrival at any given stream and watch, move slowly, watch some more, all the while putting gear together, is a much more profitable exercise than just jumping in and throwing a line. Take the time to observe things like the insect life that is present, the trout that are rising, or lack of, the lay of the stream and where the fish are or may be. The approach for arrival at the water, a walking or wading route, a line control strategy for casting (trees, wind, water flow etc.)
It didn’t take too long to dawn on me from what I was seeing, hearing and reading that there are ways to go about things for good results.
As you travel up a river and read the river, fish the river and enjoy the fishing, you notice that there are pockets of water, and sometimes stretches of water with few fish, and there are other areas where fish populations are more abundant. This is down to some of the fine detail of how the whole ecosystem works.
