Baseline Hydrologic Monitoring Plan — Hansen Project 24 <br />Table 7. Inactive Surface Water Monitoring Locations <br />Notes: <br />Station SW19 -HG and SW20 -HG were sampled from November 2008 to August 2010. A total of eight samples were collected from SW20 -HG <br />and seven samples were collected from SW 19 -HG (which was dry in 4Qtr 2009). <br />3.1.1 North Tallahassee Creek <br />Three sampling sites have been established on North Tallahassee Creek. Station SW17 -NT (Figure 9) is a <br />remote station located upstream of Project activities, at the farthest upstream location that North <br />Tallahassee Creek is believed to flow perennially in a single channel year round. Station SW18 -NT is <br />located approximately two miles downstream from the Project boundary near the historic Tallahassee <br />School House. This site typically has lower flow rates than SW17 -NT (Whetstone, 2010b). The third <br />station, SW13 -NT, is located above the confluence with Middle Tallahassee Creek and typically has little <br />to no water. <br />Figure 9.
