Watershould

Watershould is a proposed governance concept describing the minimum acceptable level of water quantity and quality required to sustain ecological and social values within a watershed. The term appears in policy and academic discussions as a way to frame how ecological health and human water use can be balanced under changing conditions.

The concept combines technical hydrology with normative judgment, treating the threshold as both an ecological target and a social standard. In practice, watershould encompasses environmental flow requirements, water quality targets, reliability of supply, and the resilience of aquatic ecosystems. It may be defined for a watershed as a whole or for specific sub-basins, and it is often used alongside traditional metrics of water availability and pollution limits.

Determination typically relies on stakeholder engagement, ecological assessment, hydrological modeling, and scenario analysis that account for seasonal variation, climate change, land use, and upstream activities. It informs water resource planning, allocation rules, drought management, and permitting processes, guiding decisions about rights, licenses, and conservation measures.

Critics note that watershould can be ambiguous or contested because it involves value judgments about the relative importance of ecological versus economic needs. Implementing it requires clear governance structures, robust data, transparent decision-making, and coordination across jurisdictions, sectors, and scales. As a concept, it remains a movement toward integrating ecological health with practical water use in governance discussions.
