instream limestone sand dosing in the allegheny plateau

Downstream Upstream

The biologically diverse stream segment is the component of the watershed, that under the normal range of conditions of consistentannual flow, alkaline buffering and stabilehabitat, a diverse community of uni / semivoltine taxa and other macroinvertebrates, are established and biologically productive, providing the building blocks of aquatic ecologic systems.
