CREATING GROWING STRONGER THROUGH
CLIMATE CHALLENGES
How the Flathead Valley's shifting water patterns create both risk and opportunity for local food systems through systemic design.
Few know better than the participants in a local food system how intimately a community is shaped by the rhythms of regional climate. It is one of the most fundamental and dominant systems by which local cultures and economies must orient themselves.
But what happens when something so fundamental starts changing its rhythms? What do you do when your choices are between stumbling into a spiraling struggle with the land and creating alignment with the new cadence?
THE CONTEXT // 01
CLIMATE AND THE VALLEY
I have been building a model to use for systemic design in the Flathead Valley. Its purpose is to identify places and dynamics where interventions lead to resolved disjunction and, even more importantly, sustained systemic improvement.
In that initial post, I introduced the structure of the model I would use to explore the systemic context of the valley. One of the core components of that model is the climate layer.
Historically, the Valley has enjoyed a relatively favorable climate given its regional position. Reliable emissaries from the Pacific Coastal systems provide distributed precipitation throughout winter and fall. The mountains encompassing the valley contribute to a robust hydrological system, most notably the snowpack and Flathead Lake, which further stabilize the Valley and provide it with special water reserves.[1]
While the valley's climate is in a state of general shift, we will focus for now on how water patterns are shifting and what that means for the local food system of the Flathead Valley.
THE PROBLEM // 02
A QUESTION
OF TIMING
What is more valuable, a quart of water or a quart of diamonds? What about when you are dying of thirst?
The word "rhythm" is used because it highlights the critical element of the water challenge faced by the valley: timing.
Historically, late spring would trigger snowpack melt, releasing a significant amount of accumulated snow precipitation (up to 100 inches) into the valley.[1] This meant that water was available later in the season, when the vast majority of the 15-19 inches of rainfall that reached the valley floor had already fallen.[2] The result was a historically consistent "water boost", enabling farmers to sustain agricultural products through the late season. This late season represents a very vulnerable period of the year, when precipitation is lowest, temperatures are highest, and the plants, animals, and soil systems are thirstiest. Water availability is the greatest protection against serious failure.
That late-season boost is disappearing. Data shows that snowpack releases are occurring earlier and earlier, taking the water boost out of sync with current agricultural practices.[1] Additionally, the flows fed by the melting snowpack are declining as the snowpack depletes.[4] Entwined with the earlier and lower snowmelt is the trend of increasing dryness and heat.[3] These three systemic forces create a greater need for water just as water availability recedes.
Risks to local producers:
Late July and through August are already vulnerable times for many food producers in the valley. According to past data, during this segment of the summer, 78% of days are dry, and evapotranspiration peaks.[3] This is when most summer vegetables hit their peak water demand. Inadequate water during this delicate time can lead to a loss of harvest, reduced production quality, and soil degradation.
Heat events are also most likely during this time. The 2021 heat dome event, which pushed temperatures to 102-105 degrees Fahrenheit across the valley, demonstrated that this isn't a theoretical concern.[5] AgriMet stations in the region record ET rates of 0.25-0.30 inches per day during heat events.[5] That means crops can lose an inch of soil moisture in less than a week without irrigation. When temperatures exceed 95 degrees Fahrenheit during flowering, pollination fails in many crops.
Drier soils reduce evaporative cooling, which can amplify heat. This is when a reinforcing feedback loop is known to form and accelerate soil degradation. Even as harvests come in, degraded soil leads to lower harvest quality.
Risks to the local food economy:
A bad year cascades. Even if the producer survives, every upset reverberates through a local system, affecting relationships and downstream viability. Local food systems are networks of trust. A producer who can't deliver consistent volume loses the restaurant account. A processor that can't get enough local cherries starts sourcing from out of state. A grocery buyer who heard "sorry, the harvest didn't come in" too many times stops making space for local. Uncertainty destabilizes local food economies.
Governance risk:
Montana operates under prior appropriation: first in time, first in right. When water runs short, senior rights holders can "call" junior rights to shut off until senior allocations are satisfied. Some senior rights in Montana date back well over a century.[8]
This creates a cliff, not a slope. A farm with junior rights may suddenly lose water access, putting it at untenable risk. The governance system wasn't designed for a climate in which shortages become structural rather than exceptional.
Three systemic forces — earlier snowmelt, declining snowpack, and increasing heat — create a greater need for water just as water availability recedes. The timing mismatch is the core challenge.
THE OPPORTUNITY // 03
SYSTEMIC DESIGN
AS A RESPONSE
While the need to adapt might seem intimidating, these dynamics offer significant opportunities. All of the risks identified above are systemic, and they are exactly the kind of challenges systemic design is meant to solve.
- Use knowledge about how general systems work to find the appropriate root risk category.
- Select intervention strategies from a list of patterns known to connect and resolve the risk category.
- Adapt the patterns to the local context until they become concrete, actionable interventions.
Step One:
The water timing problem is, in the world of general systems, known as a "stabilizing stock and flow" or buffer problem. Spring delivers a large surplus, but summer demands the draw. Using Donella Meadows' leverage points framework: buffers are "stocks relative to their flows" and act as a stabilizing force in any system.[7] As snowpack diminishes and releases earlier, the buffer that the valley's agriculture has relied on disappears.
Step Two:
Stock and flow issues have a few options: (1) Moderate the flow, (2) improve or replace the stock, (3) Remove the dependency on the stock and flow altogether.
Step Three:
Here, the systemic design opens into a marketplace for pre-existing solutions:
Moderating the buffer flow: Drip irrigation vs flood, precision irrigation via soil telemetry, shade cloth to reduce transpiration, and revised governance strategies.
Placing or replacing the buffer stock: Farm ponds, communal or civic reservoirs, deep wells, hugelkultur.
Removing the dependency: Dryland practices, new plant and animal selections, "lookahead crops", integration of permaculture, and diversification.
INTERVENTION 1 // 04
WATER-CONSERVING TECHNIQUES
This intervention aims to reduce water intake requirements and improve soil water retention.
Intervention technique:
Deep mulching (4-6 inches) combined with drip irrigation, soil organic matter building, and succession planting timed to moisture availability.[6]
5-year impact:
Despite worsening water deficits, farmers can continue to meet current local demand. Farms using deep mulch and drip report cutting water use nearly in half compared to overhead irrigation.[6]
10-year impact:
The savings from low-water techniques compound. Producers who have built soil organic matter have had more time to maintain downstream relationships while developing new ones.
30-year impact:
Farms have adapted and diversified, shoring up their own economy and those of downstream actors such as processors, retailers, and logistics operators.
INTERVENTION 2 // 05
CLIMATE-ADAPTED PRODUCTS
This intervention is about developing new, viable products better suited to the climate the valley is trending towards.
Intervention technique:
Phased transition to drought-tolerant crops (dry beans, garlic, winter squash, paste tomatoes) paired with on-farm processing capacity (drying, curing, canning).
5-year impact:
Farm trials 1-2 acres of dry beans or garlic alongside existing production. Farmers market customers discover "Flathead-grown dry beans" as a new local product.
10-year impact:
Dry-tolerant crops expand to 30-50% of acreage. On-farm processing adds winter revenue and overall value to the production chain.
30-year impact:
A cohort of valley farms has built drought-adapted production systems with integrated processing. They're selling shelf-stable local products year-round with higher revenue per gallon of water.
CONCLUSION // 06
ALIGNING WITH THE NEW RHYTHMS
The climate layer is the foundation of this model because it represents the non-negotiable constraints of the valley. The widening summer water deficit is an intimidating challenge, but it also presents opportunities to shift from reactive crisis management to proactive engineering. With proper alignment of technique, technology, and economic problem-solving, we can realign with the valley's new rhythms.
FINAL NOTE: The valley's water rhythms are shifting. The choice is between stumbling into a spiraling struggle with the land and creating alignment with the new cadence. Systemic design offers a path to the latter.
