The Bulletin recently ran a column titled “Central Oregon Crossroads: Are we moving fast enough to protect our waterways?” I always appreciate water articles and commentary, but the column did not address numerous local issues. Here’s a brief, partial overview.

Irrigators use somewhere between 85% and 90% of local water supplies. That water is mostly diverted out of rivers and supplied via canals dug into porous lava rock with a significant percentage lost to seepage and evaporation. Importantly, only part of that seepage returns to the aquifer and only after first reducing flows in a river.

Primarily at taxpayer expense, main canals are being piped, but this is a process that will take decades at an estimated cost of approximately $1 billion. There are no plans to significantly pipe the “lateral” canals that transmit water from the main canals to irrigators.

While some irrigators have installed efficient irrigation systems, many have not. For example, Central Oregon Irrigation District, the largest of the local irrigation districts, has a System Improvement Plan, which states that 25% of their “patrons” still use flood irrigation. This is a highly inefficient distribution method first developed in Mesopotamia over 5,000 years ago. Further, significant end spills (excess water running out the end of canals) continue.

End spills and agricultural runoff introduce pollution and raise water temperature in local rivers, especially the Crooked River. A water quality study released by Portland Gas and Electric, operators of the dam that creates Lake Billy Chinook, identified pollution in the Crooked River as a major source of degraded water quality in the lake and the Lower Deschutes .

Deschutes County tax policy can also be a source of water waste. Land categorized as exclusive farm use can get dramatic tax breaks even if the land has essentially no agricultural use or value. This leads some landowners to “water rocks,” as the saying goes, simply to use their water, maintain their water right and receive a tax break.

In the county, “exempt” wells can be drilled with no metering or monitoring. I have such a well, and while the rules say I can only water half of an acre, there is no measurement of how much water I pump and there are no usage costs. Exempt wells are a small part of the problem, but essentially all new development in the basin uses groundwater.

In a 2013 report, the U.S. Geological Survey stated that local groundwater has been dropping more than one foot a year since at least the mid-1990s, primarily due to a drying climate. This rate has certainly increased as drought conditions become the norm, glaciers disappear, the snowpack shrinks and population growth increases demands on a diminishing resource.

It may not be obvious yet, but we are already in a water crisis that will undoubtedly get worse. While the catastrophic ecological damage in the Upper Deschutes above Bend may be partially ameliorated due to recent changes by irrigators required by the Endangered Species Act, the Middle Deschutes below Bend, the Crooked River and Whychus Creek remain on life support due to low water levels and elevated temperatures.

As readers of The Bulletin already know, farmers in North Unit Irrigation District around Madras have some of the most productive farmland in Central Oregon but have junior water rights, and this year they will again have to leave some of their lands out of production due to lack of water. What you may not know is that many domestic wells are also going dry and local cities have limits on their ability to pump for municipal use. A shrinking aquifer also impacts local springs, which nourish wildlife and recharge rivers.

Water availability, quality, allocation, usage and monitoring are important issues in Central Oregon today — and will likely be critical in the foreseeable future. Without public demand for reform and strong political leadership, however, solutions will not be implemented.

Let’s not overlook another water guzzler. Beer. It takes on average 7 gallons of water to make one gallon of beer. That’s a pretty bad tradeoff to begin with, then you factor in that a good percentage of the final product goes outside of Deschutes it’s a lousy use of our water. Not that I'm against the micro brewery business, just pointing out the vast use of water that benefits a few financially.

No.

Ok Yancy, That's a nice essay, but you don't propose anything that even smells like a solution to this so called problem. How about golf courses? If I'm not mistaken, Bend has surface water gleaned from Tumalo Creek. And finally, if you are serious about this, you go first and decommission your well on your hobby farm. Truck in drinking water and allow your property to go back to nature. Lead by example.

Well, there are many solutions, but there is a 650 word limit for these submissions. Bend does not have surface water rights from Tumalo Creek. You may be thinking about Bridge Creek, a tributary of Tumalo Creek. You make an unfounded and untrue comment that I have a hobby farm. I do have a couple of acres, almost all of which is natural landscaping. In fact, I removed the lawns when I moved in. When discussing water, I think it's very important the keep emotions in check and extensively fact-check prior to making statements.
