Previously Planted Willows Hold Stream Banks Together
The recent flood on Bighill Creek and other surrounding trout streams was from a lot of rainfall falling in just one day. The high water levels flowed fast and furious for a breif time that was a powerfull natural event for such small streams. The recover will be quick this year!
The photo above shows how a large clump of streambank was prevented from rolling into the stream channel, by a thick clump of willows that we had planted on this site. This eroding stream bank is stabilizing over time, since the first willow plants were completed on this site.
The photo above shows how willow plants that were planted to stabilize an eroding stream bank, have survived the flood and the dense root systems were successful in preventing further stream bank erosion, at this particular site.
This eroding stream bank, like many others that have been planted, is now considered stabilized. The future growth on these sites will further enhance both fish and wildlife habitat, but also improve the water quality in the stream. It will take a few more years on many sites, for the new native willows and trees to establish root systems to help hold the soil stable, along the water’s edge in the stream.
It has been over a week since the flash flood on BH Creek and the water is still flowing high. More rain has been the reason for this. As the water starts to receed and clear up, it will be interesting to see the newly scoured streambed, with plenty of clean substrate and deep pool and cover habitat for trout.
The flood waters bent over the larger planted willows in a downstream direction. It will be interesting to see how many of these willows stay permenantly adjusted by the flood, over time.
