The Small Tributaries Loading Strategy (STLS) is overseen by the Sources, Pathways, and Loadings Workgroup. It focuses on loadings from small tributaries (the rivers, creeks, and storm drains that enter the Bay downstream of Chipps Island), in coordination with the Municipal Regional Permit for Stormwater (MRP). It aims to refine pollutant loading estimates for future TMDL and management decisions, identify the highest priority small tributaries for cleanup, and evaluate the best actions for small tributary management.
