    My permit for an eleven day Nankoweap to North Kaibab Loop had a start date of September 23rd. On the 22nd I hiked about 4 miles from Point Imperial to the trailhead just outside the park, setting the stage for an early start on the 14 miles to the Colorado River.

    On Day 2 I started around 7 am, and got to Nankoweap Creek at 2 pm. I was beat and dry, getting by on just 3 liters of water in 90°+ temperatures. But the fun was just starting, as I could see the Colorado on my way down, and it was a deep, muddy, brown. I had started after a late season storm that filled the river with literally tons per minute of silt. I pumped 4 liters of clear water from the creek and headed to the river and the bottom of the Nankoweap delta. Once there I dug two trenches in the sand to support my 1-gallon ziplocks that were to serve as "settling" buckets. I added alum, waited two hours, and began pumping. By my third liter I knew I was in trouble – the pump was already getting "stiff". (The pump was a PUR/Katadyne Hiker with a new cartridge.) I let two more gallons of water settle overnight and repeated the process in the morning to accumulate a total of 6 liters.

    GC Water1
    Well, there's a problem …

    GC Water2
    The "water plant".

    On Day 3 I started my 4 mile (river miles) trek downstream to Kawgunt Canyon. It was brutal. Temperatures in the sun were around 100°. Stopping during the day to settle and pump water just didn't seem to make sense. Had there been a trail it might have worked, but route finding, picking my way through the cactus and over the boulders, in less than optimal light wasn't an option. It was hard enough in full light. It took me 6 hours. And most of the 6 liters of water. I immediately set up the "water plant", sipping the remaining half liter as I waited. Pumping was arduous. But at least it was going.

    Day 4 was similar, starting off with 6 liters -12 pounds of water – route finding along the river for 5 miles, and then hitching a ride to below the Little Colorado River. The LCR was even browner than the Colorado.

    GC Water3
    The Little Colorado River, below the island.

    It was obvious by the amount of debris and trash that a major event was underway. And that the water issue was now getting worse. I continued, a little past Palisade Creek, to a nice sand bench for camp. It had been only a 13 mile day, but I was beat and dry. Six liters over 10 hours in those temperatures was just not enough water. My urine was a deep golden brown, and my body was complaining. I had been ready for a tough trip, but the extra 10 pounds of water weight and the temperatures were killing me. As I was pumping it became clear that the filter could quit at any time.

    I had planned on taking the Escalante Route to the Tonto, staying at Hance Creek, Grapevine, Lone Tree, Bright Angel, and then hiking out to the north rim. I could have settled water, purified with tablets, and toughed out drinking sludge for the two days it would have taken to reach the Hopefully clear water at Hance Creek. But what if it wasn't clear? I knew another major storm was due the next day which could blow out all three of those sources. And the flip side was that flows in Grapevine and Lone Tree would be so low that Only a pump could suck out the water – which I had experienced on a previous trip – and I no longer had faith in the pump. Then I considered that I had several major washes to negotiate, with flash flooding and rock fall significant concerns.

    So I decided to bail out by hiking up the Tanner Trail. Seven miles, 4,700' of climbing, 12 pounds of water, and about 8 pounds of now "extra" food.

    Day 5 was a short hike to Tanner. I set up the "water plant" hid out in the shade by the river where it was only 95°, read a little, and contemplated my fate.

    Day 6 started in the dark, pumping the last of the water for the hike out. The handle on the pump snapped on the 6th liter.

    Water4

    The decision was affirmed. I made it to the rim in 7 hours. Ten minutes later the deluge began, and continued through the night. Reports of gully washers and falling rock drifted in the next day. A Phantom Ranch camper was evacuated after taking a serious hit while in her tent.

    Lessons Learned –
    A) Take 4 1-gallon bags to reduce the cycle time. Take a "sludge filter" to improve drinking murky water. Be mentally prepared to drink less than optimal water. Go in with enough physical conditioning to cope with the extra weight.

    B) It's OK to bail out. I'm generally not one to shy away from adversity. I don't mind suffering. Type 3 Fun is fine. But in this case too many things seem to be stacking up. I think I made the right choice. Nankoweap is still there if I want to try again. And so am I.

    Hi Greg

    What can I say? I suspect I would have bailed out when I first saw the water.
    You survived.

    I used a similar setup when hiking the Paria Canyon: I used empty milk jugs to settle the particulates. Given the time need to settle and filter the water, I wonder if it would have been easier to just chemically treat the water. You have to wait for the silt to settle anyway. My 2 cents.

    Katadyne Vario:

    has ceramic pre-filter which protects the main filter and it can be easily cleaned.

    It's a little heavier filter, but being able to clean the ceramic pre-filter means you can keep on and on using it…

    I've had two PUR (now Katadyn) pump handles snap off and it's really an engineering failure since the plastic weld holding the palm push handle to the shaft is tiny and prone to snapping.

    I came up with a good fix which can take some abuse. See—

    PUR 1

    And see—PUR 2

    I just got back from an easy GC backpacking trip, and the Colorado still looks like chocolate milk (the muddiest I've ever seen it, and I've gone 1-2 times/year since 2003).

    Not surprised to hear that the river route between Nankoweap and Kwagunt is still hellish… I think I intimated that in a previous posting. Between the heat and the trees/canes/bushes, it's always a "character builder"!

    I hope you had a good trip, despite some unnecessary extra inconveniences!

    I know nothing of the area so with that in mind-
    Could you not dig a trench or hole in the sand and pump that water as it percolated thru the surrounding material? Prefilter as many times as needed with clothing to avoid the filter plugging? Just tossing ideas, I'm sure you're experienced enough that these ideas wouldn't work or you would have tried them. Would centrifugal settling be any benefit?
    Thanks for the report- still fun on my end to read of the trip.

    "I just got back from an easy GC backpacking trip, and the Colorado still looks like chocolate milk (the muddiest I've ever seen it, and I've gone 1-2 times/year since 2003)."

    By any chance did they happen to do one of their periodic "flood" level releases from the dam? As far as I know they have done this a few times on purpose, mostly experimentally, as a way to see if it could help restore the riverside ecosystem. The dam turned the Colorado below it into tailwater – great for trout but not so great for the native ecosystem. In particular it was speculated that if they let down a flood on the Colorado it would mimic the pre-dam processes that built up sand bars and places for things to grow. Supposedly it worked, but it doesn't take a genius to guess how difficult it would be to get public support for doing this periodically – say twice a year.

    I'd guess you would have heard something about it if they had done that. Seem like a weird time of year to do it as well. Probably in this case the muddy water is more of an anti-release condition. Sort of makes you wonder if having more earth around the river, as it was pre-dam, if it might filter out some of the fine silt. However, the lower green seems just as bad without the excuse of the dam.

    Lake Powell is hovering around 50% full. This year for the first time ever, Powell reduced the flow down to Lake Mead, because Mead is at its lowest level since 1937. 1937 was the year Mead finished filling up after completion of Boulder Dam. I like that name better than the new name.

    The mud is nasty silt. It can't really be filtered. Best method is to have enough water containers to let the silt settle overnight, transfer the cleared water in the morning, purify with chemicals, and be willing to carry copious volume of water in your pack. Not many willing to do this, and most people shouldn't be hiking there this time of year unless acclimated to deserts.

    The water below Boulder Dam is clear. Of course not as scenic as The Canyon.

    Good news is the Colorado will eventually fill Powell and Mead with silt. Then the river will reclaim everything. Too bad we won't be around to see it.

    What would happen if you drank that water without filtering or letting it settle? (assuming you had treated it somehow, maybe by boiling it)

    My gallon bags had about 1/4 cup of solids in them – from "flour" to identifiable pieces of "sand". I was able to get about 2 liters out of a gallon bag – so about 1/8 cup of the solids, had they not settled.

    I was going through 8+ liters of water a day.

    Eat a cup of sediment a day for a week and let me know what happens.

    "Best method is to have enough water containers to let the silt settle overnight, transfer the cleared water in the morning, purify with chemicals, and be willing to carry copious volume of water in your pack."

    This is what I have always heard Nick, though I have not tried it yet. I have always read and been told that getting water from the Green/Colorado was "impossible" without this lengthy step first as the thick silt pretty much clogs any kind of filter or pre-filter so fast.

    I am in the school with the people that say the low level of the lake is a good reason to knock the powell dam down!

    While its nice to read about pleasant trips, I always learn SO much more reading about trips that didn't go as planned, especially when it involves the kind of decision you had to make (evaluating your condition and environment, and deciding whether to bail). I personally find that these sort of experiences stay with me a lot longer (and not necessarily in a bad way).

    So thanks for the report!

    Ultralight centrifuge? It could happen!

    But seriously I love to read the definitive article on how to separate, treat and ph balance that kind of water for backpacking. While the BPL staff are at it they can also check out the sediment ingesting idea as an option. If it doesn't work they can at least sell is as a "Jackass" episode.

    As far as I can tell, the last 2014 controlled water release from Glen Canyon Dam was in April, so I doubt the muddiness is from that… However in the past couple of months, Arizona has received record/near-record rainfall from several hurricanes (including one that decimated Los Cabos, Mexico). I suspect that this unusual amount of rain may have affected the Colorado.

    The quality of the silt is really unique there. It's almost "oily" — it's just so fine. Whenever possible, I try to tank up from side creeks and avoid using the river entirely as a water source (but sometimes it's inevitable, and it really slows you down waiting for it to settle). The silt makes an already challenging environment even MORE challenging!

    After bailing from my hike, I went fishing at Lee's Ferry Arizona, the outflow of the Glen Canyon Damn on the Colorado.

    About 7 miles below the dam, the Paria River by itself was dumping a Huge amount of sediment into the Colorado. Above the Paria, the Colorado was crystal clear. Below, it looked like "chocolate milk".

    USGS staff were monitoring the flow rate and sediment load on the Paria. It was the second time in under 2 weeks that the river had "flooded". It was very apparent after letting a collection bottle settle, for less than 30 minutes, that fully half of the bottle of "water" was sediment. They said the Paria contributes about 1 million tons of sediment over 6 to 12 storms each season.

    .PariaDischarge
    The Colorado above the Paria was ranging between 8,000 and 12,000 cfs, so at times, the Paria was almost doubling that volume.

    And as I saw on my hike, the Little Colorado River was also contributing enormous amounts of sediment. In talking with fish biologists working on the Colorado, I learned it was their opinion that one particular small drainage of the LCR had flooded.

    Only one or two intense local storms are enough to make the river "muy colorado".

    Thanks for the report Greg. You had the misfortune of being in the ditch during the most impressive flood cycle since at least October of 2006. Tough conditions for sure. I'm headed down at the end of the month and am looking forward to seeing the results.

    In my experience there's not much you can do in such situations other than drink a lot of silty water. Let it settle a bit, treat it with chemicals, add drink mix, and try not to dwell on it. After a few days of that you'll be grateful to have packed extra toilet paper.

    Thanks, Greg, for your clarification of the causes of the current Colorado river conditions. I *thought* it must've had something to do with the recent rains. And it makes perfect sense that the major feeders (Paria and LCR) would be responsible for messing things up. (The smaller side creeks looked clear — maybe a bit higher flow than normal, but nothing extreme.)

    Good thing you hadn't planned a Paria Canyon backpacking trip! ;^)

    I rarely use chemicals but I've seen Chlor Floc clear up some chocolate milk water.
