P072: Sources of Fine Sediment Particles in urban roadway runoff in the LTB

This study investigated the contribution of winter time road management practices such as abrasive sand application and snow plowing to fine sediment particles in roadway runoff that enters directly or indirectly into Lake Tahoe. Reliable information regarding source apportionment of fine sediment particles is required to advance source control best management practice (BMP) to reduce loadings of fine sediment particles and associated phosphorus in winter time roadway runoff to improve Lake Tahoe water column clarity.
