Long-term Reno forecast: Below average precipitation, above average temperatures

The federal government’s long-term forecast indicates little relief could be at hand for worsening drought conditions across the Reno-Tahoe region.

The U.S. Climate Prediction Center is calling for the likelihood of below-normal precipitation and above-normal temperatures in February, March and April. The 90-day forecast was released today.

Drought prompts natural disaster declaration for Washoe County

Western Nevada Drought

Western Nevada Drought. RGJ.com map

Nine Nevada counties as primary natural disaster areas because of a drought.

The U.S. Department of Agriculture’s announcement Wednesday includes Washoe, Clark, Lyon, Nye, Churchill, Lander, Mineral, Pershing, and Humboldt counties.

Agriculture Secretary Tom Vilsack said in a statement that he sympathizes with farmers and ranchers who are dealing with the lack of rain and snow, and assured them that the USDA will stand by them.

The designation means eligible farmers can qualify for low-interest emergency loans from the agriculture department.

Counties adjacent to the nine in Nevada are also eligible for assistance. Those include Douglas, Esmeralda, Lincoln, White Pine, Elko, Eureka, Storey and Carson City.

It also includes Mohave County, Ariz., Owyhee County, Idaho, eight counties in California and three in Oregon.

Truckee River Flows at Risk for Summer

There are growing concerns we’re heading toward a major water shortage. We’re halfway through the month of January and parts of our region have only received 5% of the precipitation that usually falls in this month. December was also dry with a little over 20% of average rainfall.

Water experts say the Truckee is already at a reduced flow and it will get worse as our reservoirs dry up.

Water Conservation Tips for HOA’s and Large Commercial Properties

The challenge of watering Homeowners Associations (HOAs) and other large commercial properties during a drought can be greatly reduced by using proven maintenance practices, integrating irrigation technology designed to water more efficiently and incorporating Xeriscape principles.

 

Following are practical tips provided by Signature’s landscape experts to help large properties keep landscapes healthy while using less water.

Tip #1: Determine the best water plan

drip-hoaIn communities where mandatory water restrictions have been enacted, large properties are typically faced with two irrigation options: watering on assigned days or participating in a designated water budget program. Because many commercial properties with large landscapes need more flexibility to deliver water to all their irrigation zones, property managers may elect to use a water budget. Water budgets determine a certain number of inches per year, gallons per square foot, or percentage reduction of water use based on evapotranspiration (ET). If using a water budget, the property can normally be watered any day of the week, but is limited to a prescribed amount of water. Irrigation professionals can help develop a program that is best for the property.

Tip #2: Perform proper irrigation maintenance

Improving irrigation system efficiency is one of the best ways to save water and money not only in a drought year, but every year. At system start-up and throughout the watering season, the system should be checked for leaks and broken heads and repaired promptly. Heads should be straight and not obstructed by tall grasses or plants.
Spray heads that mist or fog are indicators that the water pressure is too high and wasting water. Installing pressure-regulating devices will save water and help apply water directly to the plants.
Replacing mismatched nozzles and installing higher efficiency nozzles also save water. Many water providers offer rebates on high-efficiency nozzles, so be sure to check rebate qualifications online or ask your landscape contractor. Drip irrigation is recommended for watering trees, shrubs and flower gardens.
Drip irrigation systems are water efficient because they are not as susceptible to water loss due to evaporation, wind or surface runoff.

Tip #3: Incorporate water-saving technology

etsystemSmart controllers, also known as evapotranspiration (ET) controllers, measure soil type and characteristics, precipitation rates, plant water requirements, and weather to deliver only the amount of water needed. Controller types, features and costs vary, and some brands allow the entire system to be maintained remotely via the Internet.
Another important and inexpensive technology is a rain sensor, which prevents the irrigation system from watering during a rainstorm. Many water utilities offer rebates on water-saving technologies.

Tip #4:  Xeriscape

Xeriscape is more than a garden style or type of plant. It is a comprehensive approach to landscaping that combines seven landscaping principles to conserve water. The process includes proper design, soil prep, appropriate plant selection, water efficient irrigation, practical turf areas, mulches and appropriate maintenance. Converting all or part of an existing property to Xeriscape is another way to save water.

Tip #5: Schedule watering based on site conditions

Several factors must be considered when setting watering schedules on large properties, including soil, slope, plant types, exposures and existing irrigation technology. To adequately determine frequency and duration of watering, water application rates, soil characteristics, plant needs, weather variation and the capabilities of your irrigation technology must also be considered. For example in May, the controller might be scheduled to apply only 50 percent of the peak water budget that would be applied during the heat of July.
The amount of water applied at any one time should not exceed the infiltration rate of the soil or water will run off. Newer controllers allow for multiple start times so that the cycle- and-soak method can be utilized for better infiltration.

Tip #6: Hire a Pro

Not all landscape contractors are irrigation efficiency experts. When interviewing contractors, ask for water-saving successes from their work on similar-sized properties.
It is important to select a contractor who understands the principles of water management and also has the expertise to operate new technology. Providing the contractor the property’s water bill will help him better assess how to employ water saving measures.
