What is drought & why is it important?
Drought is the absence of precipitation, rather than the presence of an event such as a hurricane, tornado, or fire. It's often described as a “creeping phenomenon” because it slowly impacts many sectors of the economy and operates on many different timescales.

- What is Drought?
The National Weather Service office of the NOAA defines drought as "a deficiency of moisture that results in adverse impacts on people, animals, or vegetation over a sizeable area". [15] Drought is a complex phenomenon − relating to the absence of water − which is difficult to monitor and define. [16]
Healthy ecological systems support every form of life by providing food, water, and energy; regulating pests, floods, and diseases; supporting spiritual, recreational, and cultural activities; and sustaining other critical functions, including soil formation, pollination, and nutrient cycling.

- Water Management During Drought
Drought may be caused by combinations of insufficient snow accumulation, hot and dry weather, or delay in rainfall. Drought can be further defined as meteorological, hydrological, agricultural, socioeconomic and ecological. Each definition implies different impacts. The Province's drought response focuses on hydrological drought, which is described...
The Province uses a six-level classification to rate the severity of drought conditions. Provincial drought levels are set following the guidance in the British Columbia Drought and Water Scarcity Response Plan (PDF, 958KB). Drought level classification uses core and supplemental drought indicators. Drought classification levels state the likelihoo...
Impacts to communities and agricultural production
Severe drought conditions pose significant risks to people and communities. Drought can lead to reduced water availability for household and business use. Drought can reduce crop growth and quality, leading to smaller harvests. Less water may be available for irrigation and for animal care. Hotter temperatures that coincide drought may lead to early crop maturity or ripening. The Province provides advice and drought management tools to those affected by drought and/or loss of water in agricul...
Impacts to Fish and Aquatic Ecosystems
Drought conditions pose risks to fish and fish habitat. This includes Pacific salmon and other aquatic species at risk. The Province is working with Fisheries and Oceans Canada, First Nations, non-governmental organizations, and others to develop and share information and educational materials. These groups are taking action to support priority fish populations affected by drought. This work includes: 1. Relocating stranded salmon in dewatered streams 2. Providing or improving fish passage in...
The British Columbia Drought and Water Scarcity Response Plan (PDF, 1.2MB)focuses on hydrological drought and water scarcity response actions taken before, during, and immediately after a drought. The plan identifies a variety of actions and accountabilities, including: 1. Responsibilities of agencies at the provincial, regional and local level 2. ...
Apr 3, 2024 · A drought is defined depending on the average amount of precipitation that an area is accustomed to receiving. For example, in Atlanta, Georgia, the average rainfall is about 127 centimeters (50 inches) a year. If significantly less rain falls, there may be water shortages and a drought may be declared.
The Canadian Drought Monitor (CDM) uses a variety of federal, provincial, and regional data sources to establish a single drought rating based on a five category system. These ratings are shared through monthly maps that show the extent and intensity of drought across Canada.
Drought is a protracted period of deficient precipitation resulting in extensive damage to crops, and a consequential loss of yield. Conceptual definitions may also be important in establishing drought policy.
