This data set includes N. virginea densities and sizes relative to streambed substrate type, water depth, and near-bed water velocity in three sites in a low land segment in RÃo Mameyes near PR Route 3 bridge: 1) 50 m upstream from bridge, 2) immediately downstream from bridge, and 3) 200 m downstream from bridge (upper Westin Riomar Golfcourse). In addition, above variables are reported for pools and riffles located at PRASA Intake (RÃo Mameyes) and at La Curvita (RÃo EspÃritu Santo).
