dc.description.abstract High densities of aquatic plant growth have the potential to cause dissolved oxygen depletion due to their proportionately high respiratory demand at night. Nuisance plant growth's can also degrade the appearance of a stream and can produce obnoxious odours when plant material dies and decays. A variety of methods can be used to control such plant growths. The advantages and disadvantages of several of these were examined as part of the Stratford-Avon River Environmental Management Study, with consideration being given to each measure's potential impacts on the stream environment and on water use, as well as to likely costs of implementation. The most promising measure examined was shading of the stream with bankside plantations of trees. Other methods considered less feasible for one or more reasons were mechanical and manual cropping, injection of herbicides into the stream, increased turbidity, and channelization. Combinations of measures were not examined but are potentially valid. An important method, limitation of the nutrients which support plant growth, will be addressed in another report in this technical report series.
