New York Irrigation District is a State of Idaho recognized Irrigation District operating in Ada and Canyon Counties. NYID has adjudicated water rights for 17,733.32 acres. The District currently has 16,221 water user accounts. The majority of these accounts are urban water users.
The Board of Control of the Boise Project (of which NYID is a member), annually sets the water rates. For 2017 that rate is $67.65 an acre. NYID charges a $15 per account and $1.50 per acre -- Office Charge to cover the costs of administering all of the accounts and running the District Office. NYID earns a share of the revenue of the electrical production from Lucky Peak dam and returns this to the water users. For 2017, the Lucky Peak credit to water users is $15.15 an acre.
The first irrigated farming in the Boise Valley occurred in the 1840s at Fort Boise, a fur trading post of the Hudson's Bay Company at the confluence of the Boise and Snake Rivers. Major settlement in the Boise area did not begin, however, until the local discovery of gold in 1862. By the following year, the ensuing gold rush brought almost twenty thousand residents to the Boise Valley, most had to rely on supplies of food brought from outside the region. Farmers and ranchers quickly established local operations to feed the mining camps, and by the time the city of Boise was founded in 1864, fields were already being irrigated in the valley.
Irrigation systems quickly grew from small canals dug by individuals to larger supply networks built and operated by private companies. With further discoveries of gold in the area and the arrival of the railroad in the 1880s, irrigated agriculture continued to be profitable. This in turn attracted outside capital. Larger companies developed larger canal systems, such as the New York Canal (which has since been modified by the Bureau), both for farming and to deliver water to placer gold mining operations. But by the end of the 19th century, about 148,000 acres were under irrigation, but irrigation in the Boise Valley faced several major problems, foremost among them a tangle of legal controversies over water rights and the need for upstream storage to provide reliable water supply late in the growing season.
Passage of the Reclamation Act of 1902 offered a solution to the problems, because a comprehensive federal project could untangle the legal web and could afford the cost of storage facilities. With the water rights cases about to be adjudicated, the Boise Project was authorized in 1905. It initially focused on irrigating lands along the Boise River. Major construction projects included the Boise River Diversion Dam, the Main Canal (now called the New York Canal because it follows the old New York Canal for much of its route), the Deer Flat Embankments which impounded a large off-stream reservoir known as Lake Lowell, and canals and laterals for the various irrigation districts served by the project, within 10 years, the Reclamation Service had built a hydroelectric generating plant at the Diversion Dam and another major storage facility, Arrowrock Dam at the juncture of the Boise River's main channel and south fork.
