Playing by the Hydrozone Landscaping Rules

/in , /by

Hydrozones are the different areas of your landscape with different irrigation needs. These needs can vary greatly in a single yard. By managing your water distribution to meet the needs of each hydrozone, you can minimize water waste and promote healthy plants.

For example, plants with similar growing requirements including water needs should be planned and planted together so water can be applied as efficiently as possible through rainwater catchment, supplemented by irrigation. 

The amount of sunlight and shade, temperature differences, soil conditions, slopes, and plant root depth should be considered, along with plant water needs, to create hydrozones. Even when the soil is the same, a full sun area is one hydrozone, full shade areas are another, and mixed exposure areas create yet a third zone.  

Within your irrigation system, each individual irrigation valve should water a separate hydrozone populated by plants with similar water needs, living conditions, and root depths. Plants with high water needs such as vegetables or lawns must be on their own hydrozone. Sprinklers or emitters on this zone shouldn’t water anything else, including hardscape areas such as sidewalks.  

Don’t overdo it with irrigation 

 Each hydrozone should have sprinklers or emitters generating the same amount of water, and they should be spaced out so that every plant in the zone gets the same amount of water. If the spray of two sprinklers overlap, plants receiving water from both will receive much more water than they need. In cases like this, sprinklers should be turned away from each other, or placed farther apart. Professional landscapers call this “matched precipitation.”

Oroville Dam Repairs Aren’t Enough, Feds Warn. Should State be Forced to Plan for a Mega-Flood?

/in , /by /The Sacramento Beeby Ryan Sabalow and Dale Kasler

Federal regulators are raising new concerns about the troubled Oroville Dam, telling California officials their recently rebuilt flood-control spillways likely couldn’t handle a mega-flood. Although the chances of such a disastrous storm are considered extremely unlikely — the magnitude of flooding in the federal warning is far greater than anything ever experienced — national dam safety experts say the Federal Energy Regulatory Commission’s concerns could have costly repercussions for California. The public agencies that store water in Lake Oroville may be forced to spend millions of dollars upgrading the dam.

Water Managers Along Colorado River Figure Out How To Live With Less

Climate change is growing the gap between the river’s supply, and the demands in the communities that rely on it, including seven western U.S. states and Mexico. The federal government recently released proposals called Drought Contingency Plans designed to keep the Colorado River’s biggest reservoirs from falling to levels where water is unable to be sent through the dams that hold up Lakes Powell and Mead.

Fall Back and Save Water As Clocks Change

/in , /by /Water News Network Mentioned: San Diego County Water Authority

Whether you are excited about an extra hour of sleep or dour about losing an hour of sunlight at the end of the day, daylight saving time ends Sunday, Nov. 4. The annual adjustment is a great reminder to perform several important household tasks, such as replacing smoke alarm batteries and restocking emergency preparedness kits. The San Diego County Water Authority asks residents to add one more important task when changing the clocks: Adjust irrigation systems to save water in the months ahead.

The election for the District 3 seat on the Coachella Valley Water District board could be pivotal for the agency’s future as a challenger works to unseat the current board president, potentially tilting the balance of power away from large agricultural landowners. Ed Muzik, general manager of the Hi-Desert Water District in Yucca Valley, has tried to unseat incumbent John Powell Jr., one of three farmers on the water board, with claims that he is the “non-conflicted” candidate in the race.

OPINION: Water Supplies Sufficient for 2019 and Beyond

/in , /by /Ramona Sentinelby Jim Madaffer Mentioned: San Diego County Water Authority

A welcome rainstorm in mid-October provided the first significant relief from months of very hot and dry weather — and then the weather turned hot and dry once again. That cycle is a reminder of two important facts of life of San Diego County:

  • On average, we get about 10 inches of rain a year — far less than what we need to sustain our $220 billion economy and 3.3 million people.
  • With continued investments in water supply reliability and water-use efficiency, we can continue to thrive in this amazing place.

As we look toward the rainy season, it’s worth taking stock of why we have sufficient supplies for 2019 regardless of the weather.

In a First, California Abolishes Compton’s Water District Board After Years of Dirty-Water Allegations

/in , /by /Los Angeles Timesby Angel Jennings

State officials on Wednesday removed the elected board and general manager of a water district that for years has been accused of serving brown, smelly water to its customers in Compton. With a 22-page decree, the State Water Resources Control Board abolished Sativa Los Angeles County Water District’s five-member board of directors and ousted its manager. In their place, the state appointed the county’s Department of Public Works to temporarily run the district while officials seek to merge the small district, which delivers water to about 1,600 homes, with a larger provider.

California water officials said Wednesday that the $1.1 billion spillway at the nation’s tallest dam will be in full working order if it’s needed this winter, nearly two years after it was damaged and thousands were forced to flee. Crews have finished pouring concrete on the main spillway at Oroville Dam, though it still needs to cure for a month and other work is necessary before it can be used, the California Department of Water Resources announced. Crews will also continue pouring concrete on an adjacent emergency spillway.

Battle Ahead in Colorado on Water Conserved for Lake Powell Storage

/in , /by /Water Deeply (New York)by Brent Gardner-Smith

Colorado’s western slope water managers have doubled down on their position that they will oppose federal legislation creating a new regulated pool of water to boost the falling level of Lake Powell unless Colorado adopts a policy that the pool should be filled only on a voluntary basis. At a well-attended water meeting last week, Andy Mueller, the general manager of the Colorado River Water Conservation District, said that without a new state policy putting limits on how water can be stored in the big reservoir, “You will find that our district, the Southwest District and hopefully others will be, frankly, opposing the federal legislation.”
