Blocking Watercourses and its Environmental Impact
Companies located next to watercourses or operating alongside them need to ensure that their operations and actions do not affect it in a way which violates any environmental legislation that is in place to prevent damage to the environment. This can affect companies such as timber and logging businesses who are felling enormous trees next to mountain streams/rivers which may fall in and block the flow, or manufacturing companies who are situated next to a watercourse and might accidentally or deliberately dump objects into the water, divert it or cause an environmental incident which pollutes it and proves harmful or deadly to living organisms.
Negative Aspects of a Blocked Watercourse
Whilst polluting the water and causing death or illness to fish who live in it and to animals and people who may drink or swim in it is often the primary cause of concern as it is the most common, the blocking of watercourses should not be overlooked however. Blocking a stream or river can cause flooding which can destroy animal habitats and cause damage to property. It may result in a health and safety risk if it were to destabilise buildings or structures and cause a collapse, and in severe flooding people can drown or be swept away by the strongly-flowing water.
Blocking a waterway can prevent the natural migration of fish such as salmon which travel great distances through the water to reach their breeding grounds. Depending upon where the blockage occurs it can trap fish in a certain area and result in a build up of silt and other material which leads to poor water quality and a hazard for the fish.
