compared to the pre-project periods (Figure 27). During the post-project monitoring 

 period (2002-05), densities of age 1+ brown trout were 168% higher in the wooded 

 section compared to the woodless section. Unfortunately, livestock access to the mile 

 0.5 site has confounded early phases of the study, making full interpretation of these 

 results difficult. The survey site at mile 0.8 was not subject to streamside livestock 

 damage. 



In 2005, we also established a new pre-project fish population survey upstream of 

 the groundwater influence area (mile 2.0) in order to assess the influence of planned 

 restoration. This survey revealed very low densities offish with a total trout CPUE of 1.7 

 fish/ 100' (Appendix A). This portion of channel is degraded fi-om livestock over-use and 

 appears to suffer fi-om seasonal dewatering. 



The USFWS measured stream discharge at four locations between mile 0.1 and 

 1 .8 in 2004 (Figure 25). The data shows significant groundwater inflows between mile 

 1 .0 and 1 .8 and a mid-summer peak in the hydrograph that extends into the fall. 



Water temperature monitoring has shown substantial reduction in water 

 temperatures in the newly constructed charmel, with maximum water temperatures 1 2 °F 

 lower in 2004 than the 2001 pre-project temperatures (Figure 26). 



Whirling disease sampling in 2004 recorded a continued severe 4.9 mean grade 

 infection. 



We also completed and assessment of spawning areas in Kleinschmidt Creek

Lincoln Spring Creek 



Restoration objectives: 

 To be identified. 

 Summery 



Lincoln Spring Creek is a large spring creek tributary to Keep Cool Creek that 

 forms east of Lincoln fi-om an alluvial aquifer. It surfaces on private ranch land, flows 

 through a residential area of Lincoln before joining with Keep Cool Creek at mile 0.5. 

 Excessive livestock access to riparian areas and residential development have degraded 

 and simplified salmonid habitat. Other fisheries-related impairments include irrigation 

 practices upstream of Lincoln, a reduction of instream wood and at least one stream 

 crossing (undersized culvert) downstream of Lincoln. A review of the stream indicates 

 high sediment levels and limited spawning areas downstream of Lincoln. A review of the 

 stream upstream of Lincoln suggests potential for spawning and other habitat 

 improvement measures but also low winter flow conditions. The upper portion of 

 Lincoln Spring Creek is heavily degraded and currently being considered for restoration.
