Water politics slow the flow for agriculture and downstream users
Cache Valley farmers, water managers and Utah State
University scientists came together for the annual Utah Soil Health Partnership
event today to discuss new technology and new hurdles impacting local
agriculture – and water conservation dominated the discussion.
Matt Yost, an agroclimate specialist and assistant professor
at USU, presented his research evaluating different irrigation technology and its
impact on crop yield. Yost and his research team are aiming to improve
profitability for farmers and decrease inefficient irrigation methods.
“Even in the water years where we have all the water we
need, there’s still a lot of opportunity to optimize our water use,” Yost said
while introducing new irrigation technology. Yost and his team have shown that
new sprinkler nozzle technology can use 20 to 30 percent less water than
conventional nozzles while maintaining crop yield.
Nathan Daugs, the manager of the Cache Valley Water
Conservancy district, said farmers are on board for these technological
changes. “As they improve their irrigation system, their ground becomes more
productive so they can make a better profit,” Daugs said.
While technological improvement in irrigation practices is
beneficial for farmers and ecosystems, water politics can build figurative dams
in the flow of the state’s sacred resource.
“Farmers’ biggest hurdle is the state politics,” Daugs said.
Water law in Utah has followed the doctrine of prior appropriation for more
than 100 years, stating the first in time get the first right to water.
“Ultimately, agriculture has most of the water in the state
because agriculture also has most of the land in the state,” Daugs said. “Also,
it was all agriculture to start with.”
Technological improvements to irrigation can save large
quantities of water, but land owners aren’t allowed to lease out or profit from
the remaining share of their water that is conserved through irrigation improvements.
“On the grand scale, they don’t want to do huge improvement projects cause their right gets diminished,” Daugs said.
One proposed solution involves water banking, allowing water
users to keep shares in the “bank” when unused. This allows water that may have
been otherwise wasted to be reallocated to people and places that need it.
Water banking would allow users to profit off of their unused shares and take
from the bank in times of shortage. “In Cache County, most of our water isn’t
in storage,” Daugs said. “It’s runoff water from snowpack through the year. If
it changes to more of a rain-driven scenario for agriculture, we’re in a lot of
trouble real fast.”
Daugs is a proponent of the controversial Bear River
development plan, a $1.5 billion project to build dams on the Great Salt Lake’s
largest tributary. “If it all comes as rain, we’re going to have to have more
reservoirs,” Daugs said. “We gotta be able to store it [water] and use it the
rest of the year.”
As manager of the Bear River Water Conservancy, it’s Daugs
job to plan for the future. As climate change scenarios project decreased
snowpack and population in Cache Valley is expected to double within 30 to 50
years, Daugs recognizes something has to give so water resources don’t run dry.
“So far we’ve never seen that anywhere in the West,” said
Daugs. “They find a way to bring water whether it’s over a mountain or from
another state.”
Daugs said research needs to improve knowledge regarding the
impact of potential development on the Great Salt Lake ecosystem. “Those
studies will still have to be done to see where that water is going to come
from,” he said, hoping for a balance between water for agriculture,
municipalities and ecosystems.
