Sampling comments: "Each of the four sites was sampled over four consecutive days for three sampling periods between June and September of 2006. At each site, twenty low and fast sweeps... were taken... Methods were revised in 2007 by changing site 4 to a new location... which allowed the sampling of two sites per day... This permitted seven sampling dates for each of the four sites through the summer" (total sampling effort 4 sites x 4 days x 3 periods + 4 sites x 4 days x 7 periods)
