Groundwater also provides the base flow for streams and rivers, which will be critical as flood waters recede and the hottest, driest months approach.
If that happens, you lose the base flow [the portion of water derived from underground sources] for streams, and you lose the wetlands fed by springs.
And, since base flow is synonymous with stream health and water quality, it was clear that clean water is directly linked to the canopy cover provided by trees.
