Nina Lake

Nina Lake lies west of Interstate 5 just north of the Tulalip Reservation. The lake is man-made—it was excavated in the 1970s. It is 14 acres, and is divided into two distinct basins separated by a shallow sill. The east basin is shallow—about 13.1 feet deep—while the larger west basin is relatively deep at 39.4 feet. Nina Lake's watershed, or the land area that drains into the lake, totals just 36 acres and consists of only the homes and streets that immediately encircle the lake.
