Rode LewMo twice this week so this will be a more detailed post as I saw some things that need attention. No puddles today which was good but you could see what areas were damp. They mostly just need nicks or clearing of the low side so water flows off the trail instead of sitting on it. In general, LewMo is a more novice riding destination so certain maintenance item will be different from an "advanced" rider park (know your audience).
One of the dips on the yellow roller coaster section by the lake has cut up logs blocking the drainage so water will puddle on the trail.
On the pink trail, lining the outside of the turn with rocks is not a good idea, unless you plan to build up a berm with proper water diversion before and after it. If left this way, water will be kept on the trail and accelerate erosion.
On yellow if you want to block off a shortcut line, do it at the beginning of the shortcut and don't pile rocks in the middle of it where a rider could get stuck plowing into the rocks. Now if the plan is to cover these with dirt for a roller or jump, that would be cool but don't leave a half finished rockpile for someone to crash into.
A couple logs to cut. If these were at an advanced park I'd leave them but not here. On yellow a little after that rock pile above.
On red after the TempeWick bridge. Could cut half of it out to leave an optional challenge.
And on the left yellow split after the TempeWick bridge there is a dangerous leaner for an experienced sawyer to deal with.
@Id_rather_be_skiing not sure if some of that rock work was you but just wanted to pass some of my Trailbuilder's experience and knowledge on to you
