 Welcome to Water Smart!

The following irrigation scheduling recommendations are based on data from our weather stations located in Santa Rosa. This information is also available via a recorded phone message at (707) 543-3466. Visit the CIMIS website provided by the Department of Water Resources for detailed information.

If your timer has a seasonal adjust/water budget % option, schedule your controller with a warm summer month's (July) schedule, then use the watering index on the left side of this page to adjust your irrigation schedule to match the current weather. To learn how to use the watering index click here.

* The irrigation season has ended for 2016, and as a result there will be no watering recommendations for the Santa Rosa Area. Check back in with us in early spring 2017 for water recommendations.

**For younger trees, follow the recommendations for the appropriate water use plants until roots are established. For mature trees, apply the recommended water once a week slowly to avoid runoff. For larger, well established trees apply twice the amount of recommended water every two weeks. Trees should be watered in multiple locations within the drip line (canopy) of the tree.

For help determining sprinkler type, precipitation rates, or information about using Water Smart for your entire garden, call (707) 543-3985, Monday through Thursday and alternating Fridays.

HISTORICAL DATA

The following documents contain evapotranspiration data and rainfall data for our weather stations on the East and West side of Santa Rosa. The document is separated into three sections:

Reference Evapotranspiration (ETo) Data in inches, which displays reference evapotranspiration rates for cool season turf 4 to 6 inches tall, well watered, and densely planted in large pastures.

Rainfall Data in inches, which displays rainfall data collected at the Laguna Wastewater Treatment Plant in Santa Rosa.

ETo in inches Minus Effective Rainfall in inches, which combines the data of the first two tables. Because not all rainfall received is useful to plants, rainfall data has been adjusted to account for this. That is why the title of this table refers to "effective rainfall".

Caring for Trees is a Wise Use of Water

Urban trees provide many benefits and deserve our care. They enhance our quality of life, clean the air, increase habitat, create shade and help us save energy.

Although trees in Santa Rosa usually receive plenty of rain water in winter, most trees will need irrigation in summer as the days grow longer, hotter, and drier. You can help trees on your property to thrive by watering the right amount at the right time.
