| Comments | blooming, very dense in upper river, not in lower sections yet; Weather clear, hot, light breeze. Carried boat to water at Marymoor Park, just upstream of the bridge, to launch. Took out at Kenmoor, where the river meets Lake Washington. Motored quickly between 6 stations, where we did transects with the hydroacoustic mapping tool. Saw many geese along the way. Very dense Egeria growth at the upper end. The lower river is canal-like, with more turbid water. Water level very low. |
