I drove by the stream project today in WW State Park which is just downstream of the Hwy 74 bridge. Unfortunately, all the bank sloping and just erosion control blankets did not stop an almost "total washout" of this new project. However, the banks they did rip rap did stay in place for the most part in a few small areas. Again, unfortunately, its the second time they did a project there of similar type that has washed away within the last 10 to 15 years. For those of you who complained to me about this project not being very good because it held no pool depth, was shallow and provided little trout habitat, I guess you won't have to worry about it anymore, its pretty much totally GONE! The area now has straight up and down eroded banks throughout most of its length. Of course, maybe they will spent another several hundred thousand dollars of our money in an attempt to fix it?
ADDED: to be fair, the project we are doing on Garvin Brook also received damage, but 95% of the damage was limited to soil being washed away. There isn't really anything that can be done to stop that from happening when there is a 5 inch rain fall event . That is particularly true when the banks had just been sloped and seed days before the event took place. However, what is important is the banks and structures did not washout because rock was used to make sure that would not happen. The point being is one project is almost a total redo, while Garvin Brook just needs soil put back on the rock and re-seeded. What it boils down too is the fact rock does not turn to liquid mud and wash away like dirt does.
