From The Sterling Journal-Advocate (Jeff Rice):
A South Platte River Water Update will be held in Brush on Wednesday [January 12, 2022]. The half-day program includes updates on the Master Irrigator Program, the Northern Integrated Supply Project, salinity in the South Platte and the Platte Valley Water Partnership project.
The update will be held at the Riverview Event Center, 19201 County Road 24, near Brush. It will begin at 8:50 a.m. and run until noon. Lunch will be served.
The Colorado Master Irrigator program offers farmers and farm managers advanced training on conservation- and efficiency-oriented irrigation management practices and tools. The program is the product of efforts led by several producers, district management representatives, and others interested in conserving groundwater in eastern Colorado. The program is modeled on the award-winning Master Irrigator program created and run since 2016 by the North Plains Groundwater Conservation District in the Texas panhandle.
Greg Peterson of the Colorado Ag Water Alliance and Roxy McCormick, Master Irrigator in the Republican River Basin, will present the information.
[Brad] Wind, general manager of the Northern Colorado Water Conservancy District, will provide an update on NISP. Construction has been under way for several month on the project, which will provide about 40,000 acre-feet of new, reliable water supply. The project consists of two reservoirs, Glade and Galeton, a forebay reservoir, three pump plants, pipelines to deliver water for exchange with two irrigation companies and for delivery to participants, and improvements to an existing canal to divert water off the Poudre River near the canyon mouth.
Grady O’Brien, CEO of Neirbo Hydrology, will present information on salinity in the lower reaches of the South Platte River. Salinity has been a growing problem as urban development and agricultural irrigation have added to the river’s saltiness. The water doesn’t taste salty – it contains only 0.12 percent salts compared with ocean water’s 3.5 percent – but the increasing salinity does have a negative impact on the soil. Salt in the soil suppresses the level of potassium, which is necessary for plants to take up nitrogen and create new plant material.
Old-fashioned flood irrigation used to leach the salts out of the soil, but more efficient irrigation methods don’t put enough water on the ground to do that. And, while the amount of salt in the river at Sterling seems miniscule, it is nearly twice the amount in the Denver area, just above Broomfield, and more than six time the salinity of the river above Denver.
Joe Frank, general manager of the Lower South Platte Water Conservancy District, will talk about the Platte Valley Water Partnership. It is a joint water supply project by the LSPWCD and the Parker Water and Sanitation District to use a new water right that the two entities are developing along the South Platte River near Sterling.
The project will use new and existing infrastructure to store and transport water for agricultural use in northeastern Colorado and municipal use along the Front Range. The partnership involves the phased development of the water right. The early phases would involve a pipeline from Prewitt Reservoir in Logan and Washington counties to Parker Reservoir, which supplies the City of Parker. Later developments would see a 4,000-acre-foot reservoir near Iliff on land owned by Parker, and a 72,000-acre-foot reservoir near Fremont Butte north of Akron. A pipeline, pump stations, and treatment facility will also be built as part of the project.
