UNDERGROUND WATER

Here's a link to start a search, but there's very little limit to what a person can discover online.

We’re used to water coming from overhead or from up the mountain and staying on the surface.  But there is a LOT of action under the ground.  in fact, there so much of such complexity and mythology that I can only point to categories and maybe suggest search engine material.

In spite of obviously shrinking population, Valier keeps needing more water and the water uses keep increasing rules and standards.  For instance, the old water tower that had supplied the town “forever” was measured and found wanting — not able to supply enough water to put out a fire in the school, for instance.  This was outside anything anyone had imagined, but there was no way to just ignore it.  Today there is a second water tower big enough and tall enough to need a red light on top to warn airplanes.

The well levels had been shrinking. We already had four, and wanted to sink another one.  There was enough money for four attempts.  Two were inadequate and were simply capped, though there was a scheme to use one as slow irrigation.  Things were tight, debatable, and dependent on human memory and theory about where to drill.  Finally some people insisted on a water witcher and it’s blurry whether or not that worked.  It was controversial.  In the end a successful well was found and seems to work.

Here are some stats from Pondera County.

As I began to search materials to begin this little post, I watched for hot springs, one of the most beloved luxuries of Montana, cherished by humans and bears alike.  I’m not talking about Yellowstone, which is a bit over the top, but rather the ones that have been developed into spas.  But I’ve always wanted to visit the quiet, small, nearly secret ones cherished by hippies and other lovers of the land — like bears.  I was surprised that hot springs seem only to be recorded on the West side of the Rockies.  Technically, these are surface pools, not underground.  But that may just be an artifact of reporting.  I knew a family who warmed their large chicken house with hot water from the ground.  

There’s a catastrophic side to thinking about underground water.  When the continental glaciers melted 10,000 years ago, huge aquifer reserves formed underground.  When found, we thought of them as inexhaustible and freely pumped them out to crops.  Now we discover we are emptying the spaces, creating grottoes that might collapse.  Because there is always tectonic pressure from the Pacific plate, this might weaken the area along the Rockies, creating another massive earthquake as we know has happened in the past.  There is no way to ever replenish these subterranean bodies of water.

Fracking, pumping water full of chemicals down oil wells to force out more oil, has also become a worry as ground water becomes contaminated and small earthquakes are triggered.  We have the idea that the ground is much more solid and inactive than a long term look shows us. Common ingredients of fracking fluid include methanol, ethylene glycol, and propargyl alcohol. Those chemicals, along with many others used in fracking fluid, are considered hazardous to human health.

Many old wells, some of them once artesian, even oil wells, have been simply abandoned rather than plugged and recorded.  Sometimes they are marked by rusting debris left behind or leaking poisons draining into waterways.  People have seen the hazards and costs of this failure to repair our endless burrowing and piercing, so they have worked at recording their location and size.  Legal requirements would be enforced if the miscreants could be found.

Small towns and homesteads are dependent on water.  Valier is a source of water for local “dry” farms where there is no well.  An assigned access for improvised tank trucks in town is always busy.  An earlier hydrant next to the small grass airfield had to be shut down because it had been used by a crop duster who stored his chemicals nearby.  He moved his operation to the country, but not without urging since it was so convenient.

The town itself is basically a cooperative meant to take in underground water, distribute it to households, and accept back a system of septic pipes that take it to lagoons designed to treat and settle it.  The piped systems of gas and wired systems of electricity and electronics follow that pattern.  There is always argument about how much of the underground well water is oozing over from Lake Francis and how much is following separate paths through the geology of the East Slope.  Constant testing of the incoming potable water and outgoing lagoon water is required by the state.

The Valier town employees spend a lot of their time digging up yards and streets in search of broken pipes.  The trees the residents enjoy constantly try to infiltrate water systems for their own uses.  In my yard two big fir trees have separate fates.  We removed a huge root from one that might have forced a sewer break, but the other one never gets water except from rain.  Some of us stopped watering when state-required water meters made it expensive.    Both are approaching the limits of their life and pessimists like to tell me they will fall over on my house.  They’re slanting.

The underground with its water secrets makes a potent metaphor.  I’ve stood next to the backhoe watching to see what will appear and the town workers are just as curious.  Until recently when the state is demanding a map of pipes, no one really knew what was down there or even what it was connected to — early day improvisations meant shared or doubled or abandoned lines.  At one point a city employee had asked for a device for holding ditches open so it didn’t collapse on shovelers down in the trench.  It is expensive: two big steel plates with legs in between that has to be moved by the backhoe.  The town council refused to buy one until a collapse trapped a man.  It didn’t kill him, only wrenched his back which will afflict him a long time.

We are sustained by the flow of water through the earth and sky just as we live because of the constant flow in and out of our bodies through flesh and breath.

DITCH RIDERS

So far I’ve met two ditch riders in Valier, but there must be more.  Maintenance is a big part of making an irrigation system work.  Yet this is a job most people have never heard of and may imagine amounts to nothing.  QUITE the contrary!


"DITCH RIDER" 

Job Description:
1) Controls irrigation system to convey water to farms in assigned area, according to rights, or as instructed by WATER CONTROL SUPERVISOR or other officials, for irrigating fields and crops: Contacts water users to determine quantity of water needed, and time and duration of delivery.
2) Computes and requisitions quantity of water required.
3) Operates gates, checks, turnouts, and wasteways to regulate waterflow into canals and laterals.

4) Measures or estimates diversions of water from canals and to water users, and calculates and records quantities delivered for use in computing charges to farmers.
5) Patrols assigned area by foot, horseback, or motor vehicle to detect leaks, breaks, weak areas, or obstructions and damage to irrigation system.
6) Removes debris and makes emergency repairs to banks, structures, gates, and canal roads.
7) Fills holes and exterminates rodents.
8) Writes reports and records daily deliveries, number of users, amount of water used, and other data required by law or company.
9) May prepare reports on condition of system and equipment, and replacements or repairs needed.
10) May supervise crew workers cleaning ditches, raising ditch banks, repairing concrete and wooden structures, erecting fences and gates, and other maintenance work after irrigating season has passed.
11) May take annual crop census and make weed and other surveys.
12) May patrol canal at night to determine that water is flowing in prescribed volume into users' ditches.

NIGHT RIDER

He’d been a ditch rider patrolling the irrigation canals for many years, but he’d never done it at night before.  Once he was out on the little trail along the built stream traveling from the high east slope down to the fields, he began to wish that they hadn’t given up the old system of riding horseback for the modern all-terrain vehicles.  Even lit with a headlight and knowing where he was going wasn’t as useful as a sure-footed horse that knew the path.

One would think that a straight-shot of water moving right along would keep itself clear, but that’s because they didn’t know how industrious and effective beavers can be, esp at night, nor how brush and mud caved in the sides.  A slope like that down through the foothills of the Rockies was a natural engine powered by gravity and hydraulics.  Once it got down to the flats, it could still be tricky for anyone trying to swim in it if someone upstream made a major release from the dam at the headwaters.

Animals used the canals the same way they used natural creeks, deer following along because growth was lush, cougar following because there were deer, and grizzlies because they are peak opportunists.  He was hoping that the noise of the ATV motor and the headlight would alert bears to stay back in the brush, but he spontaneously began to sing as well.  Since he was fond of the stories of the early open range, he sang cowboy songs.

The trouble with this strategy was that he made so much noise that he couldn’t hear the sounds of the night.  Maybe an owl now and then.  The sound of the water, of course.  And sometimes he could see the bright dots of deer eyes.  He could tell they were deer, not cougar, from their size, height and movement.  Small nocturnal animals also froze, glittered, slipped away.

Then the motor failed.  It would not restart.  Small motors are always tricky.  He could not think of a reason.  Silence was sudden.  He turned off the headlight to keep from running down the battery.  Now there was nothing to do but wait for morning when someone would come looking for him.  He had a powerful flashlight and a baloney sandwich.  Cell phones wouldn’t work along this stretch.  Cell phones are an urban invention.  He also had a .357 handgun, just in case.  They were a military invention, but they could stop a bear if the repellant spray didn’t work.

Now it was dark but far from silent.  The breeze sang.  Stars pricked through the sky everywhere and he wished he’d paid more attention to learning the constellations when he was a Boy Scout.  He wished for a full moon, but it was a slender little crescent.

When the bear came, he didn’t see it — just knew it was there.  The smell, but also the displacement of space on the trail.  He tried not to spike adrenaline because he knew the bear could smell it.  It didn’t seem like more than one bear, no cubs was good.  Breeding season was over so a boar would not necessarily want to challenge competitors.  His brain raced on and on, dredging up factoids and ideas that weren’t even relevant.

Time stopped.  

He wondered whether it would be a good idea to turn on the flashlight.  Even if it blinded the bear, it would be depending on its ears and nose more anyway.  If it had been later in the summer, the bear would have been so intent on eating everything vaguely edible that he would have been in more danger.  He thought about his baloney sandwich, whether he should throw it to the bear.  Would it be a peace offering or a snack that implied there might be more?  He thought ridiculously about what would happen if he threw the sandwich hard enough to hit the bear on its nose.  Should he unwrap it?

Nonsense.  Get the bear spray.  Lazily, he hadn’t put it close to hand, so would the search for the can be movement that triggered a charge?

“Whuff!” said the bear, shifting its feet, bobbing its head.  Then it crashed peacefully off into the brush along the canal and out across the empty space beyond.  When the night rider's rescuers came, he could point out the grizzly tracks and tell the story.  They would be impressed.  He might add a few details.
