CWCB: Board meeting recap

A picture named lowersouthplatteriver.jpg

From the Pueblo Chieftain (Chris Woodka):

The [Colorado Water Conservation Board] approved $1.5 million in grants following 2008 legislation aimed at meeting the needs of the Front Range. The new grants approved on Tuesday — part of a 2009 allocation of an additional $1.5 million — opened up new avenues for sharing water on the Western Slope as well. The state is studying alternatives as one way to prevent the dry-up of 500,000 acres of farmland to meet the needs of cities if the state’s population doubles to about 10 million by 2050, as currently projected…

Doherty said the second round of grants was delayed in order to determine the first group of studies was progressing. In some cases, the grants Tuesday enhance efforts already under way. Only one of the grants approved Tuesday will affect the Super Ditch, a $31,000 grant to the Lower Arkansas Valley Water Conservancy District to develop a farm financial planning tool that allows farmers to determine if selling water through lease agreements is a good idea. A similar tool was developed during the first round of studies, but it was too specific to the South Platte basin, Doherty told the board…

The board also approved a $180,000 grant for the Colorado River Conservation District that would study the establishment of a water bank of per-1922 water rights that could be used to stave off a call on the Colorado River by downstream states. That idea dovetails with a proposal by the Gunnison and Arkansas basin roundtables to establish an account in Blue Mesa Reservoir as insurance against a call on the river by California, Arizona and Nevada under the 1922 Colorado River Compact. Most of the water that is brought across the Continental Divide would be subject to curtailment if there were a call. That water represents about one fourth of the flows in the Arkansas River above Pueblo, about half of Pueblo’s water supply and 80 percent of Colorado Springs’ water supply…

For the South Platte River basin, proposals are looking at several innovations, including:

– Lake Canal Demonstration Project — A $135,000 grant would look at improving flows in the Cache la Poudre River with methods like deficit irrigation and rotational fallowing. Environmental groups support the project, while irrigators on the Lake Canal would receive money for bypassing water in an area already heavily targeted by municipal purchases.

– East Cherry Creek Water and Sanitation District — A $111,000 grant looks at maintaining productivity on land through partial irrigation or conversion to dry-land crops after water purchases.

– Parker Water and Sanitation — A $320,000 grant completes a project to determine measurement of consumptive use by irrigating crops at levels lower than the historic use of water for corn. Parker’s study, with the cooperation of Colorado State University, attempts to show how part of the historic consumptive use could be sold to cities, while allowing irrigation to continue.

– Lower South Platte Water Conservancy District — A $300,000 grant looks at numerous ways to improve efficiency in how water is used and returned to the river.

– Colorado Corn Growers Association, Aurora and Ducks Unlimited — A $250,000 grant will attempt to quantify historic consumptive use on major ditch companies from Denver to Greeley in order to develop a model on how part of the consumptive use could be sold to cities needing water.

Energy policy — hydroelectric: Boulder Canyon modernization project designed to generate 500 kW of power

Here’s a release from Canyon Hydro via PRWeb:

Canyon Hydro, a USA manufacturer of hydroelectric turbine systems, has been selected by the City of Boulder, Colorado to supply the powerhouse water-to-wire package for the 5-megawatt Boulder Canyon Hydro Modernization Project.

Some of the project funding comes from the American Recovery and Reinvestment Act (ARRA) of 2009, which imposes strict guidelines for the use of goods manufactured in the United States. Canyon Hydro is the only manufacturer of this turbine class that is entirely owned and operated in the USA.

The project involves the replacement of an existing, 100 year-old turbine system with a modern, more efficient system designed by Canyon Hydro. The new Pelton-type turbine will be specifically designed for the unique requirements of the project, including special provisions to accommodate the existing penstock (water pipeline) connections.

Canyon Hydro will manufacture the turbine at its headquarters in Deming, Washington, and at its new CNC facility in nearby Sumas, Washington. Canyon’s newest computer-controlled CNC milling machine is capable of automatically machining all surfaces of the 1.35 meter (53 inches) Pelton runner to extremely tight tolerances, resulting in very high turbine efficiency.

About Canyon Hydro

Canyon Hydro is the waterpower division of Canyon Industries, Inc. The company has been in business for more than 35 years, and manufactures its own Pelton, Francis, and Crossflow-type hydroelectric turbines. Canyon Hydro also provides extensive refurbishment and replacement services, as well as on-site machining.
