So in the interest of catching up, for starters, our endangered butterfly habitat were recently showcased on the Farm Service Agency’s blog. And, as Val mentioned, we were recently awarded Yamhill Conservation Landowner of the Year for our stewardship of them, as well as our gully plug project (more on developments there soon, I promise). I gave a talk at the annual award dinner, which seems to have gone well. If you’re interested, a pdf of my presentation is here (5Mb).

Our property is split by 4 seasonal creeks, one of which is nearly perennial. Work in the past has focused on increasing the riparian cover and shade on these creeks, and more recently, raising the water table in the perennial one, with an eye towards increasing our water supply.

The site has ~12′ of fall from the intake to the pump, and that span covers about 200′ to where the pump sits. From there, it’s around 30′ of elevation gain over 800′ of distance to get to the water storage. The pump will deliver about 1/2 gpm 24 hours a day, giving us 700 gallons of water a day to operate on, far more than our current roof rainwater tank and feeble well can provide.

Here’s a video of it in action…pardon my lack of videographer skills

The site is far from our power supply, and while we looked at solar options, the location is surrounded by trees that are growing fast. This solution should last a long time…I’ve heard of old ram pumps in California mining country that ran for decades after being abandoned.

This summer, we’ll be going on a trenching frenzy to distribute the water into all of the pastures at strategic points…I’m very much looking forward to not dragging a poly pipe and water troughs around.

Some photos and her eulogy follow, for ours, and genealogy’s sake. While she was a very active woman, the last few years saw a broken hip, with the attendant difficulties that brings. Added to that, her outliving of all of her siblings, her husband, as well as one of her children, by the end, didn’t leave her anyone left to take care of. Her active mind didn’t have anything to focus on, and she started to drift into confusion and frustration.

Rest in peace, Grandma, where clarity and vitality is yours again…we love you, and we’ll miss you.

Lorene (Rumph) Sanders was born in 1923 on a farm near Mercer, Missouri. She was raised on the farm along with her two brothers and one sister. This was a very hard life for everyone as her Mother passed away when she was ten years old. The great depression was at its peak. The farm had none of the facilities we are accustomed to today; no electricity, interior plumbing or running water. The majority of the Mother’s chores were left to Lorene. Her sister Pauline married and moved away shortly after her Mother died. Her brother, JD worked the farm and her baby brother Robert was too young to work the fields. Lorene graduated in 1941 from Mercer High School in Mercer,MO.

She married in 1940 to Joe Sanders and moved to Iowa and lived on the farm of his parents. Their first daughter, Emma Jean, was born in 1942. Later that year Joe enlisted in the Army Air Corps and subsequently was stationed overseas in the European theater. Lorene stayed with his parents to help on the farm. He was honorably discharged in 1945. In 1948 Michael was born and then in 1950 Sara was born.

Seeking a better life they moved with their three children to California in 1952. After living in the Los Angeles vicinity for two years, they moved to Palmdale in 1954 and lived in the same house ever since. Lorene, besides being a homemaker ,worked as a cook at a Lancaster restaurant and the NASA cafeteria at Edwards. Her last job was as a clerk at Boeing.

Prior to Joes death in 1981 they enjoyed fishing outings in Baja and the Salton Sea as well as outings with JD and family at Pismo Beach for clam digging and with JD’s, Robert’s and Pauline’s families for salmon fishing at Coos Bay,OR. Canning the salmon at the camp was a highlight of the trip.

Lorene loved to work in her yard with all her flowers – plant them, water them, and look at them.

One of the downsides of managing a property that has been abused in the past is dealing with erosion issues. But, as the old saying goes, crisis = opportunity. Our property was overgrazed heavily in past years, to the point that some of the wet areas were eroded over 10 feet in some places. This irreplaceable soil ended up in our local creeks and rivers, and most of it now sits in the bottom of the Pacific ocean. Meanwhile, the land responds by forming a gully, which is unstable and drains the local water table.

We’ve taken several measures in the past to fix these gullies, in fits and starts, mostly with the planting of willows to stabilize the beds of the channels. This year, I (along with technical help from friends at Waterways Consulting) ramped up the effort to keep our winter rainfall from draining away quite as fast. Hopefully, these grade control structures will raise the bed level of our seasonal creeks, and provide water for farm and wildlife later into the summer.

This pic is the site before I worked on it, except for clearing some native blackberries. It’s my highest priority for increasing water supplies, since it’s just upstream of our ram pump intake. If this treatment works as envisioned, there’s 4-5 locations upstream of here to implement more of these practices.

And the pile of equipment required

First, the channel was trenched it’s entire width and into the banks, around 8″ into each bank, and a little less into the bed of the channel. All of the fill generated was placed upstream.

Some scrap fencing was measured, along with some geotextile fabric
, to span the channel. Dog optional.

Attach the fence to the filter fabric, using wire or zip ties. Make sure that the fabric is on the upstream end of the fencing so that flows will push it onto the fence. The more holes you make in the fabric, the more points of failure you’ll have, but if you don’t have enough, the fabric could come loose. I did 1 tie every 24″ or so. Place the fence-fabric piece into the trench, and spike the fence into the banks with rebar.

Seal the ends and bottom with 3/4″- (three-quarter minus) gravel…I used about a third of a half-yard pickup load for this. Put some on both sides of the fencing, but put the most on the upstream side (the downstream side may wash away). Use some rocks or urbanite pieces to create a splash apron for the water to exit the structure safely.

Next, it depends upon the channel being repaired. This one was ~2′ deep, so the 5′ default width of the filter fabric was twice as tall as I needed. I could have cut it, but I wanted to incorporate a lot of slop into the design for this initial effort. This channel can really get raging in high water times, so if overbuilding helps it survive, then it’s worth the extra cost. And, folding the entire piece over, instead of cutting, is a bit easier since it was just me doing this

The top, or crest of the structure should be at, or slightly below, the grade of the lowest adjacent bank. The left bank in the picture is ~5′ higher than the right one, so the right one is the one we want to make sure we have the right level on. You can see the gravel and some of the salvaged concrete splash apron installed. Placing it on grade with the right bank will allow overflow to flow onto what was presumably a floodplain/wet meadow in the past. The water, even at it’s most destructive, is shepherded onto land that can spread and absorb it.

Next, install t-posts to hold the fabric-fence structure. I should have put them downstream of the structure, but some existing concrete was already in the channel, and I wouldn’t have been able to pound through that. I’ll need to tie it together tighter, and watch it during high water.

The straw/old hay bales go in next, to provide volume and roughness for sediment to deposit onto, as well as provide plants with a place to establish. We’ve used bales for erosion control in the past in this area, and when they work, it’s great, but in some conditions, high water will make them buoyant, and once they float, they’ll head downstream, taking out a lot of works in their path. 2 pieces of rebar spiked into them at an angle, and some additional concrete on top of them to prevent floating, should do the trick.

Tie the fence to the posts in multiple locations.

Add more gravel to the upstream side of the structure. I added some along the sides of the bales, and some against the structure itself. Once the water starts flowing, I’ll monitor it and see where the water is flowing, and adjust accordingly with rocks, concrete scraps, and/or gravel.

The last step for now is to compress the center or the crest downward, creating a V-shaped weir where you want the water to default to flowing. The little boy is included for scale, as well as his victorious climb on dad’s project. As well as a cautionary tale against having him choose his own clothes in the morning

It’s a little bit too early to tackle the next step, the willow staking. Ideally, as soon as the leaves come off of the local willow grove of choice, they are ready to cut. 2′-3′ lengths, 1″ in diameter, stuck into the bank in and around the straw bales, will provide root strength, which will ultimately be what holds this all together long-term.

And the final step is to wait for the rains to return, and watch it during high water. Some of my favorite pastimes. I’ll lay in a supply of rebar, gravel, and broken concrete in the event that the wooly winter that’s been forecast comes to fruition.

A gully is a response that land makes to erosion, either up or downstream of it. Upstream, flows get concentrated and speed up, and when they reach a softer point, the begin to wash away soil, dropping the level of the stream bed. This drop increases turbulence, which can increase the amount of soil washed away. As the erosion continues, the gully “walks” upstream, as it’s base gets continually eroded away.

Downstream actions can also cause gullies. When a channel is dug out (for example, in the deepening of a pond), it can create a drop location, or nickpoint. If the soil there is soft, it will create a gully that will run upstream until a balance is reached between flows and soil integrity. Often, this balance is reached in the form of an incised channel. The water level is lower than it was previously, and the soil doesn’t store as much water as it once did.

When we moved here, our dog Boomer fell into a gully created by these erosion events. We were walking through some brush, and he pretty much vanished with a yelp. After I pulled him out, I found the hole created by the gully over 6′ deep. As I got to know the farm better, I found more of these sites (but none as spectacular), usually just downstream of every place where a fence crossed a channel.

These gullies create a problem for a dryland farm such as ours. We are entirely reliant on a combination of rainfall and groundwater. While our rainfall is around 50″ per year, it mostly falls when it’s not needed, from Oct – May. The groundwater component of our water is what carries us through the drier June-Sept period, when the temperatures are warmer and most of our region’s productivity is expressed.

Part 2 runs down what we’ve done to address some of our gullies.

This was taken in March 2003 from a ladder near a spot where the laying hens had just moved from.  Note the small green patches to the left of the English Hawthorne in the midground…

and this was taken in Feb 2010 (but without a ladder).  The knee high firs are looking pretty good.

This was from the same spot as before, on the ladder in March 2003, now looking east.

and in Feb 2010

Here’s a shot looking SE, up the “Low Pass” of Old Moore’s valley road

and here’s the shot from Feb 2010 from my guesstimate as to where it was taken. A lot more trees in the valley these days.

and a 50′s-era shot to the south of South Moore’s Valley.

and the closest approximation to the location.

It’s neat to see how a landscape can change, both in under a decade, and then over the decades.

While I’ve been wanting to do this post for a while, what finally sparked me to get it all organized was this article in the local paper by a local historian. The money quote:

Puckerville, in Moore’s Valley area, tried also to become a town. In the late 1880s and ’90s, Puckerville items in Yamhill County newspapers reported talk of a new store “in our berg,” the organizing of a literary society, and this confident item: “Puckerville has more get up and go than any other town its size in Yamhill County.” But Puckerville’s “get up and go” never “got up and grew.”

It looks like my next historical investigation will be finding out where this Puckerville town was. Moore’s Valley is a very small place, so it can’t have been more than a few miles from us, but I haven’t heard anything about a town site around here. Add it to my list…

Scrape together some change and drop them some at the link below.

It’s a pretty fascinating tool…pounds of meat consumed per capita per year, access to grocery stores, WIC redemptions (pictured), and farmer’s markets are available down to the county level. We spent a good chunk of the evening playing around with it. It’s a good lead-in to Blog for Food month
