We all love a wake, but do we know the costs? There can be a bunch, depending on whether wake boats are used responsibly. Here we’ll just look at how wakes interact with the lake bottom, because wake boats can be really damaging to shallow lakes, and Lake Windermere is really really shallow!
So what’s all the fuss about? How can a wave be harmful? Well, below the surface, a lot more is going on than meets the eye. The sediment on lake beds often stores a lot of nasty things, like metals, pesticides and other chemicals. Thankfully, when they’re locked away in the lake bed, they are pretty harmless to the health of the lake.
But, when wake boats are used on shallow lakes, the wake stirs up the sediment on the lake bed, throwing it up in a murky cloud and filling the lake with the contaminants it contains. These contaminants can be damaging to wildlife and can enter the water supply.
Scientists are therefore now recommending that wake boats are not used until a depth of 8m. Sadly, the depth of Lake Windermere is only about 6m at its deepest point, and only about 3-4m on average!
But that’s not all! The wake ‘bouncing’ off the bottom of the lake also means your wave won’t be as nicely shaped: it’s for this reason that wake boat manufacturers also recommend keeping your wakes to waters deeper than 8m!
So, what to do? Well, if you need your wake fix, please do it on deeper lakes, where your wave will be all the sweeter and won’t damage the lake bed and contaminate the water!
