We use stream health as an indicator of how close we are to rebuilding a natural and resilient system. Local streams are our “canaries in the coal mine” – when they are not healthy we know that something is wrong with our watershed’s balance. When your Stream Health dial is in the green zone, it means the right balance of water is running off your land, absorbing and running underground (subsurface) into creeks, and recharging the aquifers.
