Data S1. All SNPs

Multi-locus SNP data for all individuals of known ecotype (stream-spawning and shore-spawning) at 6,145 SNP loci identified in this study. Data are presented in two-row Structure format; the first column contains sample names, the second column contains a number indicating the ecotype of origin (1=stream, 2=shore), the remaining columns contain genotypes with “-9” used to indicate missing data.
Sample names use the following convention:
-The first two characters indicate either the Stream (St) or Shore (Sh) ecotype.
-The second two characters indicate the sample location: Mission Creek (MK), Peachland Creek (PA), Powers Creek (PW), Penticton Creek (PN), Northeast shore (NE), Northwest shore (NW), Southeast shore (SE).
-The four characters following the underscore indicate the year that samples were collected (either 2007 or 2010).
-The final characters following the hyphen indicate the unique sample ID number for the ecotype, location, and year.
