Flooding Due to Lake Water Levels Rising Too High
Although not a problem in Caughdenoy Marina, flooding around lakes is becoming increasingly common. Climate change is a controversial topic, but the overwhelming weight of scientific evidence shows that global warming is a fact. While any single weather event cannot be attributed to climate change, over a number of years higher precipitation levels have led to an increased number of flooding incidents, and continues a pattern which now extends over several decades. In addition to higher rainfall levels, heavy rain storm are becoming more frequent. As a lake water rises, and the water level creeps higher and higher, the first impact is on the recreational facilities, boat ramps, parking lots and boat storage being the first affected. Next high water levels can inundate homes, close roads, displace people and animals, trigger mudslides, and wash sewage and debris into the lake. Many tons of sediment can be deposited into a lake as wind, waves and high water erode the lakeshore.
Lake Outburst Flood
Although not very common (last seen in Wind River Mountains, Wyoming), a lake outburst flood can occur when water which was dammed by a glacier or moraine (an accumulation of soil and rock) is suddenly released. These types of lakes can hold millions of gallons of water, a large part of which can be released in a matter of days. This can cause rapid erosion in a downstream river valley, or on a downstream floodplain, and are big threats to property life and basic infrastructure.
The health effects of flooding
There are a whole host of health issues resulting from discharges of untreated water and wastewater. If flooding enters residential areas, then septic tank failures can occur in addition to sewers being overwhelmed and animal waste around the shorelines is washed away. Public drinking supplies can be compromised leading to the need to boil drinking water to kill off bacteria.
Types Of Water Damage
The type of water damage including that caused by flooding is categorized into three main types.
Category One: Clean water damage is caused by non-toxic water sources. This can often occur in the home due to a broken faucet, or overflowing sink or bathtub.
Category Two: Grey water damage is caused by water that contains a limited quantity of pollutants, and can be a health hazard for local residents. This can include water from a washing machine discharge, or a cracked sewer line.
Category Three: This type of damage is as a result of flooding occurring, or sewage backing up into a home. It is the most dangerous type of damage, flood damage of this type needs professional water cleanup from experts like Enviral Restoration. Action needs to be taken immediately to prevent further damage and stabilize the situation before drying and restoration can begin.
The Nature Conservancy is working to protect rivers, lakes and watersheds – to transform the way river systems are managed and developed and inspire people to get involved. The Nature Conservancy believes that integrating natural solutions, as well as implementing agriculture best management practices, can help us realize significant cost savings alongside the invaluable return of improved water quality and quantity.
