Applicants for grant funding through Ecology's Water Quality Financial Assistance programs should use the information in this map as the default minimum riparian buffer that will be funded for best management practice (BMP) implementation in a TMDL or other water quality improvement project.  The buffer width information presented in this map is based on the 2013 Distribution of Anadromous and ESA listed fish species, and the most recent published flowlines from the National Hydrography Dataset (NHD).  Anadromous and ESA listed fish distribution data was compiled by the Northwest Indian Fish Commission (NWIFC) and the Washington Department of Fish and Wildlife (WDFW) and combined with the NHD flowlines so that minimum buffer widths could be associated with the different NHD FCodes and fish presence as outlined in Table L-1 of the 2015 Funding Guidelines (Ecology publication no. 13-10-041).Stream flowlines will only draw on the map at certain scales; if you don't see the blue and green stream lines (drawn over the basemap), then zoom in a little farther so they show up.
