the rebirth of the santa cruz river in tucson, arizona is an ecological miracle. the santa cruz river flowed year-round until human intervention dried its banks more than 110 years ago. recently, the city of tucson decided to pump water back into the river. 

after only two years of consistent flow, the river has bloomed to support dozens of mammal, amphibian, and insect species, 135 bird species, 149 plant species, and one very special endangered minnow. 

the growing interest in the river has sparked reconnection with tucson’s heritage. the city is expressing renewed interest in native ecosystems, sustainable gardening, and water conservation.

the southwestern united states is entering its 22nd year of a megadrought, making water resources more valuable and more scarce than ever before. lawmakers, scientists, agencies, and governments alike face the challenge of finding innovations to use the smallest amounts of water for the greatest total benefit. a solution to this major challenge flows through the heart of tucson. 

water conservation in the desert 

in 2001, arizona received its first delivery of colorado river water through the central arizona project canals, allowing the city to move toward more sustainable water use by using less groundwater and investing in stormwater.  in 2013, wastewater treatment plants began releasing reclaimed water into the santa cruz north of the city as a groundwater reclamation project.

reclaimed water is a way to recycle the water that comes out of a city as sewage. water treatment plants clean the water with chemicals and release it so it can soak back into the ground to recharge as groundwater.   

the water in the santa cruz is cleaned further by natural processes and eventually soaks into tucson’s aquifer. the city of tucson says that groundwater recharge with reclaimed water is a safeguard for drought for tucson. it’s a water bank for times of need.

in 2016, the director of tucson water, tim thomure, pitched a new project –– expanding the existing santa cruz recharge effort. he wanted another pipe to release reclaimed water in the heart of downtown tucson.

the idea came to life three years later as the santa cruz river heritage project.

sciences elevate the river’s health

the dragonflies weren’t the only surprise attendees at the “opening day” of the heritage project. organizers projected the event to be tiny; it was barely even advertised. there was one small tent with one crate of water bottles. more than 300 people –– and a mariachi band –– came to celebrate water returning to the river.

“it’s a trickle of water really, but such a small amount of water has created such enormous change,” bogan told me.

he wasn’t kidding; the santa cruz outflows about 1,500 gallons per minute as of 2022. for comparison, the mississippi outflows around 266,159,000 gallons per minute.

bogan and his team do continuous monitoring through species counts, species abundance surveys, and remote monitoring, which provide resources to the city of tucson to keep it healthy and prosperous. almost in disbelief, he said that, “after only 2 years of continuous flow, we’re seeing an incredible amount of biodiversity.” the rapid recovery of the santa cruz river is a beacon of hope to ecologists and citizens alike.

it seems to me that the santa cruz river has had a certifiable field of dreams moment –– with michael bogan as ray kinsella. except, in our desert narrative, the iconic line goes, “if you water it, they will come.”

the cultural significance of the heritage reach

the base of sentinel peak (known more often as “a-mountain”) has been sustaining life for over 4,000 years, making it one of the oldest sites of continuous agricultural activity in the country. the tohono o’odham and their ancestors, the hohokam, have been stewarding the land for uncountable generations. 

in 1910, businessmen drilled 20 wells at the base of sentinel peak, drying up the river completely in just five years. deprived of water, the trees that stood sentinel along the banks of the santa cruz for hundreds of years perished. for 100 years, the santa cruz has been dry and forgotten, its once-raging waters are now caged in a narrow channel of concrete. it remains as a dry scar on the landscape, like an artery with no blood to pump. 

the heritage project chose the new pipe location based on the rich history. but why is the return of water to the santa cruz called the “heritage project” and not the “recharge project”?

“returning water to the river is just one part of what ‘heritage’ means,” kendall kroeson told me as we walked the grounds of mission garden together. to kendall, the heritage project will be complete if the people, food, and history that santa cruz supported for centuries are highlighted along with the ecological success of the river.

the history of tucson’s birthplace is kept alive by the spirit of resilience and the hardworking volunteers at mission garden.

“tasting history”

kendall is the outreach coordinator for mission garden, a living agricultural museum of heritage fruit trees, traditional local heirloom crops, and edible native plants. it stands on the 4,000-year-old agricultural site.

as i spent time in the quiet walls of adobe around mission garden, i spotted hawks soaring in the crisp morning air and petit gambel’s quail scuttling under the underbrush. native habitat met flourishing gardens in a brilliant display of desert beauty.

it felt like a sister location to the santa cruz –– a sister that is upholding the heritage, biodiversity, and sacred knowledge of crop cultivation alive as she waits patiently for the river to flow again. 

mission garden is more than a connection to the past, it is an active facilitator of the future. kendall showed me a fallow plot that would become “the garden of tomorrow”.

“we need to make more food, with less land, and less water,” kendall told me. “it’s a huge challenge.”

the garden plans to showcase drought-resistant plants and drought-tolerant garden practices. it will be an example of sustainable urban agriculture for tucson and the southwest. they educate people on how to grow food themselves. backyard gardening makes food more nutritious, decreases the use of pesticides, and decreases carbon dioxide emissions.

“it is important to know what happened in the past to know what is possible for the future,” says kroeson. “here at mission garden, we’re here to help people ‘taste history.’”

generational change in tucson

“four to five generations of tucsonans have disengaged with the river,” luke cole told me.

luke is the director of the santa cruz project at the conservation nonprofit, the sonoran institute. he and dr. bogan expressed the same sentiment when i asked them, “what’s one of the most important impacts you’re seeing from the santa cruz?” they both answered that it’s the community change they’ve seen.

i talked to charles giles, a lawyer, and avid cyclist who has lived in tucson for more than 70 years. when i asked him about the santa cruz, he immediately responded that “oh, it had been dead for quite a while.” he’s right. before the heritage project, tucson’s relationship with the water that once sustained it was all but gone.

new generations of tucsonans will come to know the river as a place to learn about the value of biodiversity and the importance of water conservation. dr. bogan revealed to me that he is approved to create a program that will build a curriculum for educators of all grade levels in tucson and train 30 teachers over the next three years. he will endeavor to reconnect the newest generation with the river through the power of science and cultural awareness.

the soul of tucson

as the world faces massive challenges stemming from climate change, it is more and more important to find the most impactful solutions that need the least resources. the brilliance of the santa cruz project is that by adding water, a multitude of benefits have sprouted. cole noted the importance of this in urban ecosystems, telling me that we need to ”celebrate the multi-uses when they’re there.”

the santa cruz heritage project is making tucson more drought resilient, conserving water resources, supporting critical biodiversity, connecting a city to its heritage, and educating a new generation. the flowing river is changing the heart of tucson.

something about the sound of water in the desert sings the song of survival to the human soul. massive change can come from the tiniest of sources, just as a mighty river can be reborn from the smallest trickle. 

over the years new breeds of the popular fowl have been created to suit consumer tastes, which has resulted in the average turkey americans eat today.

this thanksgiving, you most likely will be feasting on broad breasted white turkey, like the one president obama was pictured with below in 2015 at the white house’s annual turkey pardon. this is the most commonly used breed of domestic turkey today.

the breed’s white feathers can be owed to selective breeding. according to julie long, a researcher at the u.s. department of agriculture, dark spots can sometimes be found on turkey meat due to pigmentation of colored feathers. most consumers would likely consider turkey meat covered in dark spots to appear unsightly. so, it has become common practice to breed turkeys in order to achieve colorless plumage, which results in meat void of these spots.

the broad breasted white dominates today’s turkey market. however, this genetic selection comes at a cost. traditional turkey breeds are slowly disappearing as the broad breasted white continues to be the most popular choice for thanksgiving dinner.

frank reece raises turkeys on his farm in lindsborg, kansas. he is a member of a declining population of farmers that raise heritage turkeys. these are the breeds that date back to the 1800’s. according to reece, the standard bronze is what was eaten at the first thanksgiving and was the bird that fed america from 1850 until 1950, when genetically engineered breeds began to grow in popularity.

this year, the standard bronze will make up less than 1% of the turkeys served on thanksgiving.

it makes sense for the broad breasted white to be america’s no. 1 choice. this breed grows much faster than a heritage turkey, offers more meat, and comes at a lower price than heritage breeds.

however, this efficiency comes at a price. the broad breasted white has been bred to be quite large and, as a result, it is unable to fly on its own. this weight is also responsible for a number of health issues. many of these turkeys suffer from heart disease, respiratory failure, and have shorter life expectancies than other breeds.

according to us news, the turkeys pardoned by president obama in 2010 died the same year due to health issues that came as a result of selective breeding.

this thanksgiving, consider a variety of options when choosing a turkey. the higher price tag of a heritage breed not only helps a struggling industry, but is by far the most authentic route to take.
