High Water Across the West: The Truckee River

Returning once again to my spring mini-series about all the rivers and lakes that are at higher levels than I've seen in quite awhile (most recent post), I decided this time to show a few pics of the Truckee River, which I drive by quite frequently. Actually, I drive by four times a month unless I happen to bypass Reno by taking another route: 1) across the Black Rock Desert, 2) via Wadsworth to Pyramid Lake and northward (this route is currently impassable because spring floods washed out the road), or 3) over the mountains from the Pyramid Lake highway to Highway 395 (when having to turn around because the preferred road was washed out north of Sutcliffe).

The first photo was taken at a scenic overlook near Patrick along I-80, looking to the southeast. The river is high between us and the dark brown mass of intrusive dacite that forms a synform known as Giant's Throne (you can read a little about this feature here or purchase the field guide here).
Here (above), from the same location, I zoomed in on the river just south of I-80. The trees were just getting their spring leaves and were bright yellowish green.
After a bit, I pulled off at the westernmost Fernley exit and drove south into Wadsworth, a small town along old highway 40 (which is not signed 40 anywhere in Nevada, afaik). These photos, above and below, were taken at a bridge over the Truckee in the eastern part of Wadsworth.
I zoomed in on the water roiling downstream from a cottonwood tree sitting farther out in the water than usual.
I couldn't resist a photo of this old church. Once upon a time, while in high school or early college, I painted a watercolor of a similar church located back east in northern Virginia. I'm still fascinated by the style — not sure why.
Unlike some other rivers in the west, the Truckee was nowhere near impacting the old highway 40 bridge from below.
The railroad bridge spans the Truckee less than 50 meters away from the highway bridge.
For some reason, this view looking downstream reminded me of swamps in southeast. Maybe it's just the way the trees were sitting out in the river.
While down on the river between the two bridges, I grabbed one more shot of trees out in the river. And after standing there for a few minutes, I remembered I had to get back on the freeway. 😢

All photos were taken on 14May2017. The river is still high.

High Water Across the West: Rye Patch Dam and the Humboldt Sink

Rye Patch Dam on April 19th. The water in Rye Patch Reservoir is high, but not at the high water mark that can be seen just past the spillway.
I'm moving slowly on this mini-series about the Humboldt River while working essentially 12-hour days and while (hopefully) recovering from some long-lasting bug I caught on the road or out in Elko more than two months ago. Also, my current work schedule of  9 to 10 days in a row gives me 2 to 3 days off that don't involve driving, so my off days tend to be filled with chores and not that much writing. Anyhoo, there I was traveling south on I-80 past the big bend at Humboldt Station, where I had stopped to take a few photos of the water in the Pitt-Taylor Reservoirs, when I decided—rather spontaneously—to drive down to Rye Patch Dam. As you can see from the first photo, the reservoir is high, but not quite to the high water mark.
Rye Patch Reservoir and Majuba Hill.
Here we're looking just west of north across a shallows, and we can see Majuba Hill just right of center in the distance. The main, deeper part of the reservoir is long and linear where it follows a canyon cut by the river into Lake Lahontan sediments.
The same view in June, 2016, from Google Earth.
A few Western Grebes swim in the shallows.
A closer view of one grebe.
I couldn't resist this view of the Humboldt Range.
Snow-capped Star Peak hides behind clouds. The Cordex Pit of the Florida Canyon Mine operations might be barely visible below Star Peak.
After my brief sojourn at the Rye Patch Dam overlook, I proceeded back to the interstate, speeding ever southward and then southwestward as the road made another broad bend near Lovelock. I was shocked at what I saw when I drove past Granite Point.
The Humboldt Sink had water in it!
At first, I thought it might be a mirage, and although these photos don't really do justice to it, it was indeed water, a small lake that has persisted, at least through my last drive by the area a week ago on June 11th.
A closer view of the Humboldt Sink and the West Humboldt Range.
And that's all for now, time for work! I've got a few pictures of even more water from another trip, but I can't promise when I'll get to it!

High Water Across the West: The Humboldt River at Winnemucca and Humboldt Station

When I started putting these photos together—while thinking about our last post about the Humboldt River in Carlin Canyon—I somehow (and quite erroneously) figured I could throw a whole bunch of high-water Humboldt River photos together in one blog post. The thing is, I have way too many, from several different localities and a few different days, and I hope to collect a few more before the water ebbs. So for today, we'll stick with these two spots, which I visited while driving I-80 from Elko to Reno on April 19th. The first shot looks westward toward Blue Mountain from the westbound exit onto West Winnemucca Blvd (exit 176).

The flooding in Winnemucca was really quite extensive when I drove through on April 11th (no photos) and then again on the 19th: several backyards and a few basements or first floors of houses near the defunct "Barrick Arms Apartments" were under water. The water had receded incompletely when I saw it last (May 28th).

These first pics show the Humboldt River's floodplain looking more like a marshy lake than it's usual dry self. Water level was slightly lower on April 19th than when I first saw it on the 11th.
Here's a phone-camera panorama, with Blue Mountain way off on the left and Winnemucca Mountain taking up the right half of the photo.
This Google Maps Street View image, a flashback to 2011, shows a more typical appearance of the same panorama, albeit from October rather than spring.
And just because, I've included a picture centered on Winnemucca Mountain. It's a prominent feature and a landmark for miles and miles. If you look closely, you'll see the two-toned "W" painted on its southeastern slope.

On that same day (the 19th), I pulled off I-80 at Humboldt House (exit 138, marked "Humboldt") and drove old Highway 40 back toward Imlay.
I crudely spliced together two or three photos looking northwest across what I thought was Rye Patch Reservoir.
It turns out that the entirety of the water seen in these photos is contained within the Upper and Lower Pitt-Taylor Reservoirs.
Here we see Majuba Hill behind blue water in the Lower Pitt-Taylor Reservoir. The light beige horizontal line between the water and Majuba are bluffs underlain by Lake Lahontan's Sehoo Formation. A narrow part of Rye Patch Reservoir proper runs between us and those bluffs, but we can't really see it, even though the water is running high.
Here we can see both the Lower and Upper Pitt-Taylor Reservoirs. The Lower is closest to us; the Upper is beyond the horizontal pale beige line separating the two bodies of water. The wide upper part of Rye Patch Reservoir lies not far beyond the Upper Pitt-Taylor, hidden from us by some irregular low hills. Off in the distance, we're looking at pointed, snow-covered King Lear Peak, part of the Jackson Mountains. The 8923-foot-high peak (2720 m) is about 45 miles away.

High Water Across the West: Honey Lake

I've recently had the opportunity to travel across part of the Great Basin of eastern California and northern and central Nevada, and have noticed a lot of high water, almost everywhere. Honey Lake, which has been dry to only partly filled during the last several years, is once again a lake. The first two photos are from the 11th of April; the last three are from the 25th.
The lake is beyond full for what has been typical for several years, with bushes drowned around the edges and fences under water. In fact, you can see a bit of a fence or gate in the picture above, near shore, a little right of center. Most of the fenceline is completely under water.
Here's a relatively broad view of the lake taken on April 25th.
I cropped the previous photo so it would closely match the first photo from the 11th.
And this photo matches the second photo from the 11th. If you look closely at the two matching sets, you can see that the water was slightly higher on the 11th, and had gone down a teensy bit by the 25th.

I have several years of pictures of Honey Lake: there are these comparison photos from 2007 through 2011, these few photos from May and June of 2015, and one photo from early March, 2016. Even more photos can be found by searching the blog for "honey" (along with a few from nearby Pyramid Lake). Most of my photos through the years have been taken from the Honey Lake Rest Area).

The Caliente Series & Caliente Camp Series

I'm bringing everyone up to date about my Caliente series because I'll be adding new posts soon. The series is multiple in nature: two related series have been running side-by-side. I'm calling the first one I started the "Caliente Camp series" and the second one the "Caliente series." In real time and in blog time, the Caliente Camp series started before the Caliente series.The Caliente Camp series: These posts are mostly about a helicopter exploration camp I was part of in 1978, with some accounting of the two 2009 road trips I took to the area to travel down old roads. These stories will continue have now been completed.
The Caliente series: These posts are mostly about my 2009 road trips to the Caliente area, although part of the two trips are documented in the Caliente Camp series, and some 1978 stories are told in at least one of the Caliente series posts. The Caliente series includes a couple posts about the geology and rock formations of the area, and other related items like the wildfires that were in progress during my second field trip. These stories will also be continued have been completed.
These two series overlap, and I've switched back and forth between the series, partly because I started the Caliente Camp series before I made the second road trip into the area and didn't know what kind of series I was starting.

Friday Field Photo #4

Gateway to Northumberland Canyon; photo looking east.

The entrance to Northumberland Canyon, coming in from Big Smoky Valley in central Nevada, is marked by a sentinel of Northumberland Tuff overlooking a dry wash that was in high flash-flood conditions on August 7, 1979, while I was doing field work in the area.

Well, that's a great lead in, but what I really wanted to do was post a field photo before Friday was completely over, and it looks like I've just barely made it. I took the photo a couple weeks ago while out driving around.

The cliff of strongly welded Tertiary ash-flow tuff looks like it may be capped by some black chert, and that would be Ordovician Vinini Formation chert on top of Tertiary ash-flow tuff. If that's what it is, it's pieces of chert and slide blocks the size of trucks, and larger, that slid into the caldera, forming an intracaldera breccia and slide-block formation that we called Unit 1, way back when.

A bit more on that later.

Summit Lake and Beyond: AK2008 Day 2

lodge We arrived at Summit Lake Lodge, which is for sale in case you are interested, in time for a slightly late lunch.
paws A friendly bear greeted us...
tables...so we went on in, found a place, and sat down. Summit Lake Lodge has good food, good beer, a good atmosphere, and a good view.
view Sometimes it's worth stopping at the gift shop at the south end of the parking lot - to get milkshakes, espresso, T-shirts, or other gift-type items.
shakes

lakeAfter lunch, we headed south on Alaska Route 1 to Tern Lake, where the Seward Highway continues south to Seward as Route 9, and the Sterling Highway continues west towards Sterling, Soldotna, Kenai, and Homer as Route 1. Tern Lake is a great place to stop to see wildlife, to stretch your legs, and to get a good view of more mountains and another great U-shaped glacial valley, seen above looking southeast towards Moose Pass.
graywackeAs you drive away from Tern Lake, to the west and back toward the Sterling Highway, you'll have ample opportunities to stop and examine several metagrawacke roadcuts like the one above, which is cut by a network of quartz veins. In fact, you can't miss seeing the slaty graywacke, even if you don't stop at Tern Lake - there are several good collecting places here and there near the triangular junction of the Sterling and Seward highways.
creekSuddenly, the parental driver (my dad) took a sharp left turn, and we headed into the woods toward the Tern Lake campground. fishiesA short walk from a little pullout on the dirt road before the camp will take you to Dave's Creek, a good place to view spawned out red salmon.
fishThe red salmon, or sockeyes, are still hanging around, some going barely going upstream, most barely holding their own against the current.
creek Above, the photo looks back toward Tern Lake at the head of Dave's Creek. Downstream and to the west, Dave's Creek joins Quartz Creek and empties into Kenai Lake near Cooper Landing. It's amazing: all these lakes have creeks and rivers going into them and out of them, and all of them eventually empty into the ocean! (Well, maybe I've been in the Great Basin too long - actually thinking that lakes and oceanward drainage are amazing.)

road The road goes on, pointing more-or-less toward Redoubt Volcano, which can't be seen through the clouds on this particular day.
cabin Finally, then, we found the right turn-off from the Sterling Highway, and we made our way on pavement and the dirt to the cabin - seen above in an earlier rendition before it was lifted off the ground after the September 1995 flood, which occurred not long after the painting of this strange picture.

Flash Flood on Highway 50

brown bushes As MOH and I were driving over Mt. Airy Summit west of Austin the other day, our first clue that thunderstorms had caused a little flash flooding was the brown, muddy, knocked over bushes on the side of the road.

mud Our second clue was - lo and behold, some actual mud and wet ground - in Nevada!

disturbed Our third clue was that someone had recently been pushing some dirt around, as though the water and sediment had actually flowed across the road.

equipment Ah, and who's been moving the dirt? Yes, there was a little construction activity in progress as we drove slowly through!

summit1 Mt. Airy Summit is a broad, almost unnoticeable summit about 15 miles west of Austin, and all the flooding activity had seemingly taken place on the east side of the summit. It didn't look like there was a whole lot of drainage area upstream from the flash-flooded dry washes - some washes on the north side of the highway and some small drainages right along the road.

Mt. Airy Mesa, the hill shown in the photo above, is formed of columnar-jointed ash-flow tuff sitting on some white to light greenish-yellow poorly welded tuff or lake deposits, the latter of which are strongly clayey.

mapThese rocks units are denoted as Tt2 and Ts2 on the Geologic Map of the North-Central Nevada, which are designated as being in the 34 to 17 Ma range. The large square in the map above is a township, about six miles on each side. [Note: this map shows Highway 50 going through Railroad Pass to the south on the road now known as Nevada S.R. 722, formerly known as Route 2, and before that known as Highway 50.]

summit2 The drainage area for the flooding seemed small to me, and possibly the clay in the Ts2 unit contributed to runoff. The thunderstorm must have dumped a lot of water really fast in the highlands at least on the north side of the highway, and possibly on the south side. [Note: "dumped", "a lot", and "really fast" are technical terms - well, I mean, I wasn't there when it was raining, and can't find a single thing written about this little flash flood that must have taken place on July 24th.]

deposits If you're working in an area, you can examine flash-flood cuts and deposits like this one when they are fresh. In a year, come back and look again: the dry wash will look much the same, but the bushes will be in better condition. If you come back year after year, you can gradually get an idea of what a dry wash looks like after a certain time has passed, and you will be able to estimate the date of the last flash flood by looking at any dry wash anywhere.

The fact that a particular dry wash flooded within the last year, or hasn't flooded for ten years - using the above estimating method - doesn't really say anything about whether the dry wash is ripe to flood again anytime soon, so don't use that estimate as a guide to whether you are safe from being caught in a flash flood. Some drainages seem a little more prone to flash flooding, and some types of drainage areas are more dangerous to be in during a rainstorm.

It would have been fairly easy to get above the flash-flood at Mt. Airy Summit because very few of the dry washes overflowed their regular stream banks; when they did, the water wasn't very deep - judging from the muddy watermark on the sagebrush maybe a foot or two at most. However, there would have been no way of knowing at the time how long the rain would fall or what size the flash flood would be. So it's a good idea to get to high ground when rain is pouring all around you or when it's falling upstream. Flash floods can run for miles and can carry large boulders or even pickup trucks with them.

sand springsWe saw only minimal evidence for other flash flooding between Austin and Fallon, Nevada - above, a little flash flooding had been going on on the west side of Sand Springs Pass, about 25 miles east of Fallon. Location of the photo is near Bench Mark 4372 in the lower left (southwest) part of the linked-to MSRMaps map. I've only been near one stream when it was in flash-flood mode. Water was roaring down the little stream on the west side of the Virginia Range south of Reno, Nevada. It never rose high enough to overflow the banks, but the sound of boulders smashing against one another was impressive.

UPDATE 11Jul2010: A good place to view the results of the flash flood, some of which can still be seen east of Mt. Airy Summit, is to park south of Highway 50 on the dirt road shown below, and to cross to the north side where the wash is about to go under the road.
