Fire has not yet reached either Landers Camp Spring or Kelso Valley Rd. I was section hiking along that section thru end of Wednesday (6/22) & shuttling some hikers around on Thursday (6/23). Most hikers are off the ridge line above Kelso Valley Rd due to the heat at midday combined with gale force winds at night (40-60 mph). Have to go to ground with shade at midday & cannot hike at night in gale force winds.

Hiked northbound from Cameron/Willow Springs Road to Robin Bird Spring.

At approximate Mile 562, significant erosion damage (2′ deep trench) on short stretch of trail. Easily side-stepped, but will continue to worsen.

At approximate Mile 565, steep hillside in state of extreme deterioration. Trail tread was sound and passable, but hillside above and below trail is unstable and is washing away.

From Mile 566.5 to 566.7 (the stretch of trail parallel and alongside Hwy 58) the trail has been obliterated due to heavy flooding. It was easy enough to follow however. Trail conditions okay above gate and beyond.

The most serious conditions and the primary reason for this report were blowdowns below Cache Peak, where trail leaves road MK10 and becomes single-track again, and Robin Bird Spring. I lost count of the blowdowns, in excess of 50 downed trees. Soft, moist soil and heavy winds took down live and dead trees in and out of burn area

Bird Spring Canyon Road (mile 631) inaccessible to vehicle traffic

On 6/13/15 a localized thunderstorm dumped 1.6 inches of rain on Bird Spring Pass (mile 631) in one hour, cutting the road two miles from its intersection with paved Kelso Valley Road. There may be more damage to the road higher up its approach to the PCT, but either way it’s impassible to vehicle traffic until repaired. I haven’t checked the approach from the east, but that may be washed out as well, and is in any case sandy enough 4 wheel drive is recommended.

Yellow Jacket Spring on the Pacific Crest Trail

May 29th, 2015

In 2014, we walked northbound along the Pacific Crest Trail until there was a sign that said ‘Yellow Jacket Spring’ and your only choice is left, which was down, down, down the trail. It’s this ragged trail (.7 miles) down and there is a clear path for about .5 miles and then it gets kind of lost. You just keep going down until you hit the valley floor. It gets difficult at this point and there is a rough path to the left and nothing really to the right. It’s obvious that your goal is left. However you keep searching but there is no true water. What you need to do is travel a bit left (south) and find the most damp ground. From there you can dig and seep water. We were able to spend our time and gather about four liters each (sucked) and be on our marry way. Remember though, .7 each way. The way back up I wanted to throw my life into the bushes.

Golden Oaks Spring repair

Check out our blog post about the repair: The glory of Golden Oaks Spring.

May 15, 2015: 

I think we have a reasonable flow for the hikers. The two sources of water (spring box and stream directly into the trough) come from different spots on the hillside so they are somewhat independent of each other.

Jerry, Pete –

Observations/measurements around 3PM on 5/14/15.

The trough had 4 ½” of clear water.  Flow from the slope into mid-trough was still good.  Hikers had built a causeway of large stones to get directly across to it without getting feet wet and left an open 1 gallon container beneath the drip for a minor reservoir for the next hiker – looked good.

Soil at the outside trough corners indicated leakage like what I saw last time – probably through the trough near the left corner; maybe around the trough at the right corner.  From last patching, looks like we were able to get about 2 more inches of trough water depth than before when it was about 2 ½”.  No apparent cause for the leakage, but they can be difficult to track down sometimes.  However, looked to me like enough depth for stock and the bear to be able to drink from easily.  Also, some hikers said that they filled directly from the trough, since it was clear and was faster.

No flow from the PVC into the trough at the right corner.  The syphon through the ¼” ID tubing had apparently outpaced the spring box replenishment and run dry; probably with about 4” of water in the spring box.

The water had returned to 19” deep at the spring box – it was ¼” lower than the outlet and likely stabilized at that level.

See table below for measured flows.  By inserting the smaller ¼” OD (0.156” ID) tubing into the ¼” ID tubing, the flow reduced from 19.6 GPM to 17.3 GPM with an estimated head of 27”.  Raising the tubing 6” at the PVC access coupling to reduce the head to 21” lowered the flow to 15 GPM.  Feeling that 15 GPM might also break the syphon, I removed a barb from a dead end of fencing and inserted it through the smaller tubing to further slow the flow.  Doing so outputted 11.7 GPM at the trough.  I left it at that.

Since head pressure is another major factor in flow, if the SB level does draw down (by output outpacing replenishment) the reduced head combined with the barb restriction in the tubing might just balance and produce a steady flow.

May 8, 2015: We made a return trip to the spring yesterday to complete needed repairs. John Shelton and myself hauled in equipment and supplies. We drained the concrete water trough and patched known cracks that leaked. It would only hold 4 inches of water before. We created a syphon for the spring box to drain to the trough. I’m not sure how successful this will be. John stayed over night last night and will adjust the flow today so that the level will stay the same in the spring box. Yesterday when we finished it was slowly going down. The existing flow that drains directly into the water trough continues from our last trip at a rate of about 1 Gal. every 15 minutes. What ever we end up with now is all we will get until Mother Nature gives us rain. We hiked a 2 mile section of the trail north of the spring to clear a know reported tree down on the trail and removed it.

April 30, 2015: I just returned Monday from Golden Oak Spring with my PCTA volunteer crew. The weekend went well as far as accomplishing what we planned. We brushed the whole hillside to see where we could grab any water flow. We dug 2 channels towards the spring box. I got in and cleaned out the box and brushed the sides to open any blocked wholes. We had some flow going into the box and thought if we drilled a few wholes we would get more. Bad idea!!! The water went in the box and as best I can figure went out the holes we drilled because the water never reached the height of the exit pipe. We also cleared a channel that drains directly into the watering trough. All these channels are lined and filled with rock. We replaced all the plumbing and modified the fence line to hopefully protect it from future damage.We tightened the complete fence line around the spring and repaired a corner H brace. The watering trough is cracked in one corner and leaks out as much as flows in. There is only about 4 inches of water in it.

We had extra time Sunday afternoon so we surveyed the trail in the burn area north of GOS. A total of about 3 miles. Found around 15 trees down on the trail. So Mon. morning set out and cleared these trees. I know there are more trees down north of the Green gate which is 6 miles north of GOS.

My plan is to return maybe next week and patch the trough and install a syphon which should create a small stream from 1/4 inch irrigation poly pipe out of the spring box through the plumbing to the trough. It should be a little clearer than the ground water seeping into the trough.

So in short it is a little bit better with potential for a little more. But it will still be taxed when the large volume of hikers go through in the next 3 to 4 weeks. Thanks to all my hard workers and Bill Carter’s fence expertise.
