Table 6. List of aquatic species identified in the Texas Comprehensive Wildlife Conservation Strategy that are found in the Trinity River basin but not originally nominated by TPWD biologists. Species Status Known Host Spawning Season Stressor Notes MacNeeses crayfish Fallicamberus macneesei Steigmans Crayfish Procambarus steigmani Bigclaw River Shrimp Macrobrachium carcinus Creeper Mussel Stophitus undulatus Texas emerald dragonfly Somatochlora margarita Fishes American eel SC NA Spawning usually in September (early fall), egg release normally in April (spring) SC NA Spawning usually in September (early fall), egg release normally in April (spring) SC NA Probably carry eggs in March to September. SC Largemouth bass, creek chub, green sunfish July to April and May; may not need fish host SC NA Very little known about biology or larval habitat. Defined as vulnerable by AFS due to narrow range and sensitivity to pollution, habitat change and modified flow regimes, only found close to coastal areas within 50 miles According to AFS this species is in imminent danger of extinction or extirpation throughout large portion of range. Found in the extreme northern portion of the Trinity Basin, lives in higher elevation riparian prairie Dams limit upstream migration of juveniles. Adults migrate to freshwater and release hatched larvae. Found many sites, but rare not seen in state of Texas since 1992, rated stable by AFS. Limited in Texas to a few counties adjacent to the Trinity River and E. Texas. Endemic to two states in the United States (Louisiana and Texas). The species currently is known from six counties in these two states. This species has a restricted range (currently only seven locations are known). SC NA Jan to August in mid- Dams impede upstream Anguilla rostrata Atlantic - Catadromous movement of juveniles Blue sucker ST NA Late April to May Abundance of Cycleptus elongatus Cycleptus elongatus has been decreased by impoundment, pollution, and reduced water flows in those systems in which it occurs. Creek chubsucker Erimyzon oblongus ST NA March to May Not listed by AFS. Sabine shiner SC NA May to December N. sabinae was designated a Notropis sabinae species of conservation concern in Texas and Louisiana by U.S. Forest Service Region 8 and U.S. Fish and Wildlife Service Region 2, and as a species of special concern in Mississippi Sources: (Abbott 2006; Bender et al. 2005; Bonner 2009; Hobbs III 2001; Howells 2009; Howells et al. 1996; Jelks et al. 2008; Johnson and Johnson 2008; Kondratieff 2000; Taylor et al. 2007) X = Recent Occurrences (within last 30 years); Status: TWAP-SC = Species of Concern, TPWD Texas Wildlife Action Plan 2005 1 = State Rank (S1) – Critically imperiled, extremely rare, very vulnerable to extirpation, 5 or fewer occurrences 2 = State Rank (S2) – Imperiled in state, vulnerable to extirpation, 6 to 20 occurrences 3 = Proposed for Federal Listing 37 Environmental Institute of Houston November 17, 2009 Trinity River Basin Biological Overlay
Results Hydrology Summary Graphical summaries of the hydrology at each priority USGS gage site were used to illustrate seasonal and annual trends. One very obvious trend that was observed is the decline in average daily flows at the USGS Elm Fork gage after 1951 (Figure 6). The initial decline occurred during the drought of record, but flows never did substantially increase after this period (Estaville and Earl 2008). This is probably due to the construction and filling of Lake Grapevine Lake and Lake Lewisville reservoirs which are located less than 5 miles upstream of this gage and were first impounded in 1952 and 1954 respectively (Richard Browning TRA – personal communication)(Farquhar and McDonald 1991; Gandara and Jones 1995 )(Table 7). Seasonally the lowest average stream discharge occurs during the months of August through October with little variation (Figures 7-9). Largest daily fluctuations and overall variability of flows occurs during the months of January through June (Figures 8 and 9). Highest average daily flows also generally occur during these months (Figure 7).
