Take care that you do not yield to temptation and just take a little peep too many and from too close a vantage point whilst out with the dry fly early in the season. Right now our allies in the margins have not yet grown high enough to help us in our attempts to be unnoticed by the fish.
You may find some blades of fleur-de-lys are high enough now for you to hide amongst. If so, do use them where you can. BUT... whatever you do, you must resist the temptation to raise your head up to get a better view of the rising fish. These pictures help to illustrate the point. The first is what you might see while standing well back from the water's edge and so unseen by the rising fish. Having spotted the rising fish you sneak in low to hide amongst the cover.
The second picture shows you what your (hidden) head height view is likely to be. It is not as easy to see the rises. That is when the temptation is strongest. Resist it! Make your cast and reap the reward of your stealth...
