Saying we're in "high water" conditions is an understatement. Water is at the top of the information sign at the beach entrance. The bridges on 101 are intact, but when I rode through the medium length one before the one with the guardrails near CX Hill, the weight of a bike on the bridge pushed it down enough to get water through the slats. There is a spot not far from there where the trail is impassable due to water (one of the bends around the low lying areas) and a bypass is already starting to appear. The water was almost at the bottom of the large bridge on 101 and the CX Hill bridge is washed out again. There is also one part of 101 where the water partially covers the trail. I'm sure by the time I type this, the trail will be covered there. The lowest lying, farthest south area (nearest the lake) in the first part of 201 is also underwater and a bypass is forming. I did not make it in to the 300 (or through much of the rest of 201) as I had a fairly catastrophic sidewall puncture that left me walking out.
Everything that isn't underwater looks fine, but obviously we're going to continue to see issues while the water rises and the bypasses that are being created may not be desirable long term.
