Opinion: California Can’t Waver on Water Regulation

/in , , /by /CalMattersby Samantha Arthur and Ngodoo Atume

Over the past decade, California has gone from being the state with the least groundwater regulation to adopting a law that serves as an international model. How the state implements its landmark groundwater law during California’s worst drought on record could inform global climate change adaptation practices for generations.

The Golden State has one shot over the course of the next 20 years to bring its depleted aquifers into balance and achieve sustainability. Californians are counting on the Sustainable Groundwater Management Act to get the state there.

Water Conservation is Critical in San Diego County as Colorado River Declines

/in , /by

Sandra L. Kerl, general manager of the San Diego County Water Authority, issued the following statement in response to the U.S. Bureau of Reclamation’s 24-month projection for water levels in Lake Mead and Lake Powell.

“Today’s announcement by the Bureau of Reclamation is a reminder of just how important it is to increase water conservation across San Diego County and the rest of the arid West. An increasingly hot and dry climate is creating unprecedented challenges for water supplies that will impact life in the Southwest for the foreseeable future.

“The San Diego County Water Authority continues to participate in discussions about the future of the Colorado River. We also continue to highlight the value of the conserved water transfer agreement between the Water Authority and the Imperial Irrigation District, the cornerstone of the landmark Quantification Settlement Agreement, or QSA, negotiated in 2003, as well as our investments in concrete lining sections of the All-American and Coachella Canals to conserve water previously lost to seepage. Through the QSA, the Water Authority funds critical conservation efforts in the Imperial Valley that provide the San Diego County region 277,700 acre-feet of highly reliable, cost-effective conserved water supplies each year. Further, the QSA enables California to live within its historic 4.4-million-acre-foot annual Colorado River apportionment while providing a roadmap for current efforts to balance the complex economic, agriculture, environmental, most notably the Salton Sea, and water-use needs in the Colorado River Basin.

Colorado River water

“The Water Authority has not been asked to make any voluntary reductions to Colorado River water supplied by IID under Reclamation’s call for additional basin-wide conservation. If cuts were deemed mandatory to IID through an official Secretarial declared shortage to Priority 3 water in California, the Water Authority would take a pro-rata reduction of its IID transfer supplies.

“Investments by San Diego County residents in other water sources and storage facilities will continue to shield the region from the worst effects of the drought. At the same time, the potential for mandated water-use reductions should inspire every San Diegan to decrease their water use, for instance, by taking shorter showers, reducing irrigation of decorative grass, and upgrading to efficient appliances.”

Can The Lake Powell Pipeline Still Happen?

/in , , /by /Salt Lake Tribuneby Brian Maffly

Already in doubt from the West’s changing climate, a proposed pipeline across southern Utah remains bogged in a regulatory limbo that could hold up the project indefinitely.

If built, Utah’s 143-mile Lake Powell pipeline would draw up to 86,000 acre-feet of the Colorado River’s flow — depleted by drought and overuse — from the ever-shrinking Lake Powell for use in St. George and Kane County.

By the time Utah water bosses clear a stalled environmental review and secure the water rights, however, there may be no Lake Powell as we’ve known it, just a “dead pool” stacked behind Glen Canyon Dam. Complicating this bleak picture is the pipeline’s current design, which places the intakes above the lake’s future levels, leaving them high, dry and unusable if the drought continues to drain the lake.

7 States and Federal Government Lack Direction on Cutbacks From the Colorado River

/in , , /by /KUNCby Luke Runyon

As the Colorado River shrinks, the seven states in the western United States that rely on it for water and power need to cut their use dramatically to keep the biggest reservoirs from getting critically low, according to federal analysts.

But a recent deadline for a plan to conserve an unprecedented amount of water came and went without many specifics from either the states or the federal government on how to achieve the cutbacks.

The Fight Against Drought in California Has a New Tool: The Restrictor

/in , /by /CNNby Stephanie Elam

The pretty, cloudless blue skies over perfectly manicured lawns represent an ugly reality for California’s Las Virgenes Municipal Water District as it grapples with the historic megadrought ravaging the American West.

Despite a lack of any measurable rain in months, the carpet of lush, green grass likely means homeowners are either not getting the message about the dire need for water conservation, or they are ignoring the warnings.

Getting the Dirt on Healthy Landscape Soil

/in , /by

Soil is essential to a healthy landscape and efficient water use. Learn about your soil’s characteristics and how to care for it. The results include easier maintenance, a healthier environment, and a more beautiful landscape.

Here are some simple tests to help you evaluate your soil.

Soil Drainage Assessment

Evaluate your results based on the drainage rate. First, dig a hole 12 inches wide by 12 inches deep. Set aside the soil for additional tests.

Next, fill the hole with water. Let it drain overnight. Then fill the hole with water a second time. Set a stick in the hole so water just reaches the top. In one hour, measure the drop in water from the top of the stick in inches.

Drainage less than one inch per hour: Poor Drainage. This may be due to high clay content or soil compaction. Add compost to the soil before planting to improve soil aggregation and water infiltration. Select plants that can tolerate poor drainage or consider using raised beds or mounds. Regular surface applications of shredded mulch may be helpful for long-term management. Irrigation should be scheduled for short cycles and long soak periods to meet plant water demand and avoid runoff.

Drainage is between one to three inches per hour: Acceptable Drainage.

Drainage more than three inches per hour: Water moves too quickly through your soil. Add compost before planting to hold the water in the root zone longer and select plants tolerant of fast drainage. Regular surface applications of shredded mulch may be helpful for long term management. Irrigation scheduling may require longer watering times to ensure plants have enough available water at the root zone.

The Worm Test is another method of providing insight into the health of your soil biology. Sift through the soil removed to perform the drainage test. If you can’t find at least ten earthworms, your soil is low on organics and will benefit from the addition of compost when planting. Use shredded mulch after planting to continue to feed the beneficial organisms. Worms help reduce soil compaction, allowing water and air to move into the soil to provide healthy growing conditions and maximize efficient water usage.

Determine Your Landscape Soil Type: Squeeze It and Jar It

The Squeeze Test can help you determine the texture of your soil. Start by taking a handful of moistened (but not wet) soil and squeeze it firmly. Open your hand and determine which of the following it most resembles.

High clay content soil. Holds its shape and does not crumble when you poke it lightly. Sand is quick draining but has a limited ability to retain nutrients and moisture. Sandy soils often benefit from the addition of organic matter.

Loam is generally considered ideal soil because it retains moisture and nutrients but doesn’t stay soggy. Clay is typically nutrient-rich but has poor drainage. Drainage can sometimes be improved by deep cultivation which breaks up the hard layer of soil

For the Jar Test, use a one-quart size glass container, such as a Mason Jar. Add one cup of soil from the garden. Add three cups of distilled water. Close and shake the jar until all solids are suspended in water.

Place the container on a shelf and wait 24 hours. If the container is cloudy, then wait another 24 hours. After 48 hours, the layers should be settled with sand on the bottom, silt in the middle, and clay on top.

Measure the layers in proportion to each other. Refer to the graphic to determine your soil type based on the proportions of sand, silt, and clay. Refer to the USDA soil triangle with the soil separation percentages to determine your soil texture.
