Runoff water is one of the leading causes of wild salmon decline. It carries pesticides, motor oil, and antifreeze to the rivers, which makes the breeding process harder as the eggs and hatchlings can’t handle pollution. For that reason alone, there is a need to reduce runoff water and also keep potentially harmful chemicals out of its way.
It’s a good idea to plant things where runoff water collects. The roots absorb some of the water, leaving the rest to dissolve in the soil slowly. However, you might want to do some homework to avoid plants that cannot handle wet feet. The last thing you want is a dead garden in the front yard.
The use of porous material is recommended
Naturally, rainwater is supposed to soak in the soil. But most people cover their compounds with materials that don’t let water through. As a result, the runoff water meets in the drainage systems, carrying everything in its path. To avoid this, use permeable pavers for the driveway and plant grass and flowers in the rest of the space.
Roofs collect a lot of water during a storm and harvesting it goes a long way in reducing runoffs. The idea is to trap water in a container for a sunny day. It can be used to fill up a pool or water vegetation. You can also direct the water to Dutch drains; gravel filled barrels with holes at the bottom. They hold water long enough for the ground around it to absorb it all.
Use organic fertilizer
Organic fertilizers are non-toxic, and that makes them a perfect source of nutrients and minerals for your plants. Most processed fertilizers contain harmful substances that may end up polluting rivers. Using compost in your home garden will keep your soil healthy and help save salmons.
