For instance, if there is a so-called “bathtub” – a depression between the beach and the first sand bar - very near the coast then this will have to be fished thoroughly before you start wading out. The water in here is relatively stagnant and is quickly warmed up by the first spring sun, and that will attract freezing trout. It is not uncommon to make contact with the first fish of the day in here. Not until the bathtub has been checked thoroughly will you be able to wade further out and continue fishing.
However, the fish are often found on the outside of the first sand bar rather than in the bathtub. Out here they have easy access to deep water if threatened by anything. It makes them feel safer and therefore easier to get to. Discounting early spring, when the heat of the sun is important for the fish, the very low coastal water is most productive during the hours of darkness. The fish will usually be found in this water predominantly in early morning and late in the evening – as well as at night.
If you are walking or wading along the coast, check the water by spreading your casting in the shape of a fan in front of you. If you are standing on a large boulder or a marked point, the thing to do is to spread your casting in the shape of a fan so that all the water is fished thoroughly. If wading is necessary, it should always be done with care. It is particularly important to be careful where the bottom is made up of large, slippery stones. A long wading staff is an excellent help. It can be used to feel the ground and for support in difficult situations.
