Seasonal Water Needs
Want to do your part to save water? Grass needs much less water in April, May and September. Adjust your lawn watering based on Spokane and Kootenai counties seasonal watering needs. A calendar of watering needs was calculated using daily data from local Agrimet Stations for the years 2015, 2016, 2018, 2019, 2020, and 2021. A three-day running average was calculated to estimate how much water you would need to apply to your lawn if you water every three days. Notice how much less water is needed in spring and fall.
