    1 3. Aquatic Habitat Baseline Conditions 2 The project is located in the Lake Washington watershed, which comprises 13 major 3 drainage sub-basins and numerous smaller drainages, totaling about 656 miles (1,050 4 kilometers) of streams, two major lakes, and numerous smaller lakes. Lake Washington and 5 its major drainages (Issaquah Creek, the Sammamish River, and the Cedar River) are located 6 in the Cedar-Sammamish Watershed Basin, or Water Resource Inventory Area (WRIA) 8. 7 The majority of the watershed is highly developed, with 63% of the watershed fully 8 developed; WRIA 8 has the highest human population of any WRIA in Washington state 9 (NMFS 2008a). Lake Washington is the second largest natural lake in Washington with 10 80 miles (128 kilometers) of shoreline. The lake is approximately 20 miles long 11 (32 kilometers) with a mean width of approximately 1.5 miles (2.4 kilometers), has a 12 circumference of 50 miles (80 kilometers), covers 22,138 surface acres (8,960 hectares), and 13 has a mean depth of approximately 100 feet (30 meters) and a maximum depth of 14 approximately 200 feet (60 meters) (Jones and Stokes 2005). 15 3.1 Lake Washington Hydrology 16 The Lake Washington watershed has been dramatically altered from its pre-settlement 17 conditions primarily due to urban development and removal of the surrounding forest, as well 18 as the lowering of the lake elevation and rerouting of the outlet through the Ship Canal. As a 19 result, the Cedar River is now the major source of fresh water to Lake Washington, providing 20 about 50% (663 cubic feet per second [cfs]) of the mean annual flow entering the lake 21 (NMFS 2008a).

  • Saltwater Intrusion in Salmon Bay and Lake Union Sediments
    A D e p a r t m e n t o f E c o l o g y R e p o r t Saltwater Intrusion in Salmon Bay and Lake Union Sediments Abstract Saltwater intrudes into Salmon Bay as a result of operation of the Hiram Chittenden Locks, which connect the Lake Washington Ship Canal with Puget Sound. Depending on the levels of salinity present, sediments in certain areas may be classified as marine, low-salinity, or freshwater. These classifications can affect sediment cleanup decisions. To evaluate the appropriate classification, sediment pore water salinity levels in Salmon Bay and Lake Union were determined using conductivity and temperature measurements. The results were then compared to sediment pore water definitions in the Washington State Sediment Management Standards (WAC 173-204-200). Pore water salinity results were also compared to the U.S. Army Corps of Engineers (USACOE) real-time water column monitoring data, to see if these data sets could be correlated for predicting pore water salinity levels. o o Pore water salinity values ranged from 0.16 /oo (parts per thousand) to 13 /oo. A little over 50% of the sediment samples collected had salinity values that would classify them o as low salinity sediment (>0.5 to <25 /oo). Under conditions present at the time of sampling, there was a trend towards lower salinity levels moving east from the locks. Sediment pore water conductivity data were correlated with USACOE data for two of the transects, using multiple correlation equations. The models describe conditions at the time of the study.

  • Smallmouth Bass Collected at the I-5/University Bridge Site
    SPRING/SUMMER HABITAT USE AND SEASONAL MOVEMENT PATTERNS OF PREDATORY FISHES IN THE LAKE WASHINGTON SHIP CANAL FINAL REPORT, 2006-2009 to SEATTLE PUBLIC UTILITIES by Roger A. Tabor, Scott T. Sanders, Mark T. Celedonia, Daniel W. Lantz, Steve Damm, Terence M. Lee, Zhuozhuo Li, and Benjamin E. Price U.S. Fish and Wildlife Service Washington Fish and Wildlife Office Fisheries Division 510 Desmond Drive SE, Suite 102 Lacey, Washington 98503 LWSC Predator Acoustic Tracking, 2006-2009 FINAL DRAFT September 2010 EXECUTIVE SUMMARY Federally-protected Chinook salmon Oncorhynchus tshawytscha and other juvenile salmon in the Lake Washington basin must migrate through the Lake Washington Ship Canal (LWSC), a narrow, low-velocity artificial waterway. In this waterway, juvenile salmon are vulnerable to predatory fishes, including the non-native smallmouth bass Micropterus dolomieu and largemouth bass M. salmoides, and the native northern pikeminnow Ptychocheilus oregonensis. Some diet and abundance information on these predatory fish has been collected (e.g., Fayram and Sibley 2000; Tabor et al. 2004) but little is known about their habitat use and movement patterns. Chinook salmon habitat use patterns in the LWSC have been characterized in Celedonia et al. 2008b and Celedonia et al. 2010. The relationship between juvenile Chinook salmon habitat use and predator habitat use is important to understand for management of Chinook salmon in the Lake Washington system. This study used acoustic tracking methods to define habitat use and movement of these juvenile salmon predatory fishes. The objectives of this study were to 1) describe the habitat use patterns of smallmouth bass, largemouth bass, and northern pikeminnow and determine their relationship to existing overwater and in-water structures; and, 2) determine seasonal movement patterns of these species, with particular emphasis on if and when they move between the LWSC and Lake Washington.
