Sprague Brook will hold up to heavy rains well because the trail layout is designed in such a way that it really isn't susceptible to washouts. The last time I was there after a heavy rain all the drainage was perpendicular to the trail and flowing into well established drainage tracks which is totally different than water flow on a fall line trail (like those driveways Geoff)which is what causes washouts. Point of reference is the ATV uphill / downhill that is directly down a fall line and is highly eroded. The only other place that is susceptible to washouts is the snow mobile trail which is about 75% fall line from top to bottom and is why it appears slightly different at the bottom after every heavy rain. It's high on my list to layout a single track to the west of the snow mobile trail with multiple switch backs (hopefully non bench cut) which is sustainable and a lot better climb than the snow mobile trail.

My dog and I hiked the entire trail yesterday and then some more today. There are some deep mud holes but no wash outs

I was over into Eden and Boston Sunday and there must have been some flash flooding. A lot of wash outs, Clarksburg Rd was closed due to debris and damage. There were several gravel driveways that washed down the hill into the creek.
If that cell traveled East over to Glenwood, I am sure that more than a little of Sprague Brook washed out.

A lot of work still needs to be done on the west side, and will be, especially come fall when trail work days start up again.

But, if it remains dry like it has been for a week now, yeah you can ride. Hopefully tonights rain forcast will be light or non-existent.

Woohoo, no rain today after all. The whole loop might be in good shape for the group ride Wed. See you all out there after work.

I went out and checked things out tonight. I saw where you had knocked down the berms starting on the west side. Itworked perfectly and those sections were well drained after Saturday's drenching rains. Further up that side was a different story, though. The "accidental section" was a real mess. I think that while we should fix that with some corduroying sometime, we should also just clear out the original intention out to the pipeline. There is a wet section or two on the old road that we meant to use, but the sides of the road are high and dry. That way you could just use the accidental section when it is dry. Elsewhere out on the west side there are more berms to knock down and several very short sections in need of corduroy, and the trail should then be fine. But until then, there are many wet sections on that side. The very wet area just above the trail just before the crossing of the Brook definitely drained onto the trail, but there's not a whole lot you can do right there.

The east side, in great contrast was great. 99% of the time the drainage was working well, with only the occasional spot with no drainage, but those were only a few feet in length.

If the rains aren't too hard with the front coming through tonight and there's riding Wednesday before the meeting, I would strongly suggest just riding on the east side. Do it out and back a couple of times.

As for technique in knocking down the berms, you did a great job. The key thing I was concerned about was that some might just cut a small channel hoping the water would drain out. That works well until the first bike comes through and blocks out the small channel. Don't laugh, I've seen it done before. The way to take care of the berms is to pull it away the whole length of the blockage and then some.

Eventually, what you want is to be fully down to the mineral soil. As one may notice, anywhere where there was a bench cut (i.e. into the mineral soil) the trails were extra great. Basically, the goals should be to see none of the black soil that you see now in most of the piney sections. That all needs to be removed so that you can see the light brown mineral soil. That will happen with use, but it is better to remove as much as you can manually or else the organic material will end up as a new berm.

Jon,
Ben and I were out putting up trail signs on Tuesday afternoon. We knocked down some of the berms (Ben showed me how to do it, so if it's not right... blame him) on the side that starts clockwise. Hopefully this rain is draining better in those areas. We only made it about 1/4 way around so thier is much more to do.

Jon, I already have a list of interested people that I'll forward to you (with e mail addresses) for this exact purpose.

I thought you were to busy but looks like your back :D so might as well let you handle this.

If anyone is headed out there tomorrow I get out of work at 4 and can head that way to help out. It is supposed to be a nice day I hear. I would need to see how it is done since I have never done trail work yet.

If we could find the time to knock down the organic material berms, it would take only a day of dry weather to get the trail ridable. If someone does have the time, let us know and we can fix you up with instructions (there is a right way and a wrong way to do this) and some tools. It doesn't have to be a formal scheduled work day. A lot can be done by a single person with some free time. Indeed, the trail has benefited quite a bit from Kevin and Ben doing the "single person with some free time" thing.
