2-020 -A Site Summary- San Joaquin River, Stockton to Lathrop Reach 2-020 -A <br /> Thomas Guide Location Latitude N Longitude W <br /> County: San Joaquin SF Bay and Delt 3757 121 20.2 <br /> USGSQuad: Stockton West NOAAChart: 18661 SACRAMENTO/SAN JOAQUIN RIVER <br /> Last Page Update: 7/1/1996 <br /> SITE DESCRIPTION: <br /> Site is from intersection of San Joaquin River and Deep Water Channel at the Port of Stockton (R 48) up river to <br /> south 17 miles to 1-5 at Mossdale. This channel is relatively narrow and occasionally winding. It is bordered witf <br /> heavily ripped levees, but there are occasional pockets, some quite sizable, of natural mature riparian vegetation <br /> and occasional marshes. The water supports warmwater species, and the smolts from three salmon runs <br /> migrate through this reach. <br /> SEASONAL and SPECIAL RESOURCE CONCERN <br /> Marsh and riparian areas found here are "A" priority at all times. Several Special Status Species are found here: <br /> Swainson's Hawk(ST) and tri-colored blackbirds; one rare plant. <br /> RESOURCES OF PRIMARY CONCERN <br /> Pockets of remnant riparian forest and marsh, some quite sizeable, remain scattered along this ripped reach. <br /> Aquatic environment supports freshwater community and is a migratory route for several salmon runs. Low <br /> dissolved oxygen can stress this community in late summer. <br /> Special Status bird Species here are Swainson's hawk (ST) and tri-colored blackbirds that nest and forage along <br /> this reach as do many other waterbirds and riparian species. <br /> Other vertebrates include riparian and semiaquatic species such as deer, fox, raccoon, mink, muskrat, beaver, <br /> snakes, lizards, amphibians, etc. This may be habitat for western pond turtle. <br /> This area has typical warmwater aquatic community. The remaining salmon runs of the San Joaquin salmonid <br /> stocks migrate through this reach; smolt survival in this area is key to those fish stocks. <br /> Slough thistle occurs here. Key vegetation here are mature riparian pockets and small marshy areas. <br /> CULTURAL.
