Book excerpt: Excerpt from Aquatic Pests on Irrigation Systems: Identification Guide Extensive infestations of obnoxious plants and certain aquatic animals cause problems on irrigation systems, such as reduction in carrying capacity of the system, increased evaporation and seepage, clogging of structures, adverse environmental impacts, and water loss through transpiration. Because of the many problems created by these growths, steps are usually necessary to control them or prevent their occurrence. The methods employed to control these plants and animals differ widely due to differences in the organisms, such as growth habitat, organism metabolism, size, growth stage, and genetic characteristics. Correct identification of the organism is therefore important to the proper control recommendation. The simplified identification guide was prepared in response to requests from irrigation project operators and other personnel involved with biological problems requiring identification aids. It consists essentially of an illustration and a narrative description of some of the commonly observed organisms that become pests on the operation of irrigation systems in the Western United States. Not all animal pests that inhabit irrigation systems are included because many of these common ones such as muskrat, certain fish, and crayfish are readily recognizable by irrigation operating personnel. Some of the more serious and marginal ditchbank weeds have been included to illustrate a few typical problems on canals and drains.
