Swalley Water Rights

Despite being one of Oregon’s smaller irrigation districts, Swalley has returned the largest amount of water to the Deschutes River (through its conservation projects) than any other district. In 2009, the District completed the piping of 5.1 miles of its main canal along with several smaller laterals. Altogether, the District has returned ~39 cfs of water, with an 1899 water right (the most senior on the river), to the Deschutes River. This extrodinary conservation effort has benefitted ~45 miles of the Deschutes River, from the North Canal Diversion Dam in downtown Bend to Lake Billy Chinook. Since 1995, the District’s annual diversions from the Deschutes River have effectively been reduced by nearly one-third, leaving more water in the river for salmon, steelhead, other fish and wildlife, and recreational benefits.

Season 1: April 1 - 30 & October 1 - 31

Druring these times, we deliver at the 30% rate. Our maximum diversion is 34.548 Cubic Feet per Second (CFS) from the Deschutes River. Swalley has no storage rights or reservoirs to draw from. Due to cold/wet Fall weather or scheduled maintenance, the District may decide shut down early. In such an event, notifications will be posted to this website and sent out to patrons where/when practicable.

Season 2: 50% - May 1 - 14 & September 15 - 30

Druring these times, we deliver at the 50% rate. Our maximum diversion is 46.199 Cubic Feet per Second (CFS) from the Deschutes River. Swalley has no storage rights or reservoirs to draw from.

Season 3: 100% - May 15 - September 14

During the peak of summer, at the 100% rate, Swalley delivers water at ~7 gallons per minute (gpm) per acre. For example, if you had 2 acres of water rights, your delivery would be ~14 gpm. If you had 0.5 acres of water rights, your delivery would be ~3.5 gpm. Our maximum diversion during the peak sumer season is 87.217 Cubic Feet per Second (CFS) from the Deschutes River. Swalley has no storage rights or reservoirs to draw from.











Central Oregon Irrigation District (COID) & Swalley Intermingled Deliveries
Swalley and Central Oregon Irrigation District (COID) have an agreement to exchange certain deliveries on the edges of the two districts' delivery systems where better delivery can be provided to the customer due to proximity to certain facilities. This is a long-standing agreement confirmed by the State Watermaster for Oregon Water Resources Department (OWRD).

Deliveries made by Swalley to COID customers must follow Swalley water right delivery scheduling as well as the rules and regulations of Swalley (and vice versa). Note: Some COID deliveries may be placed on certain rotation schedules as deemed necessary by COID. Deliveries to Swalley customers made by COID follow COID's delivery schedule (and potential rotations). For more information, please contact either the COID or Swalley offices.


Avion Water Deliveries

Avion Water is a quasi-municipal water supplier in the Central Oregon area. In some subdivisions they provide dual piped systems which provide both drinking water and irrigation water. In some cases they deliver Swalley irrigation water rights to customers through their own private infrastructure. When that occurs, the billing is made by Avion and paid to Avion and the delivery is the responsibility of Avion Water. Avion Water pays the irrigation assessment to Swalley, and then passes that assessment and the cost of delivery on to their users. If there is not adequate water delivery or a problem occurs, Avion will contact the Swalley office to keep customers informed.


Conserving Water

Irrigation districts throughout Oregon’s Deschutes Basin are implementing an array of water conservation, fisheries improvement, and hydropower projects. These projects help hardworking small family farmers and ranchers raise crops, and benefit the environment. Since the 1960s the Deschutes Basin Districts as a whole have significantly reduced their water use. These conserved water supplies are increasing instream flows in the Deschutes River, Crooked River, Whychus Creek, Tumalo Creek, and other smaller tributaries; improving habitat for salmon, steelhead, other fish and wildlife; and providing recreational benefits. Many of these projects, such as piping irrigation canals, also increase public safety and create the opportunity for developing small hydropower generation with zero carbon emissions.



Swalley's Ponderosa hydroelectric plant was built in 2010, making it the first small-scale hydroelectric plant built in the state of Oregon since 1990.
