The Nature Conservancy Council has welcomed the implementation of the EC Directive on the assessment of the effects of certain projects on the environment. This paper discusses its implications for nature conservation in fresh waters, particularly with reference to the land‐drainage and flood‐defence work carried out by the National Rivers Authority and its predecessors, to which the regulations SI 1217 apply. Environmental statements have been deemed necessary for only a small proportion of capital schemes initiated by the water industry since the Regulations came into force in 1988. The author has evaluated the nature‐conservation content of 15 of these statements against a combined set of objective and subjective criteria. The statements examined showed a high degree of variability in length, scope, style and presentation. In general, survey and data acquisition were poorly covered. The weakest area was considered to be the evaluation and prediction of potential impacts, and this is discussed in relation to the uncertainty and complexity inherent in biological systems. The need for monitoring the accuracy of predictions after the completion of a scheme received little attention, despite its fundamental importance in improving future project design, and in extending scientific understanding.
