<br />3.3. SURVEYING THE REACH <br /> <br />3.3.1 EQUIPMENT REQUIRED - The following is a list of equipment needed <br />to conduct a slope-area survey. <br /> <br />1) Transit or total station equipment & tripod. <br />2) 25 foot rod (If you have 2 rods, you can work both sides of the stream at the <br />same time.) <br />3) Clipboards <br />4) Notes <br />5) Survey flags (minimum 150) <br />6) Orange survey tape (2 rolls) <br />7) Hip waders for rod men <br />8) Machete <br />9) Hammer <br />10) Insect repellant <br />11) Drinking water <br />12) Calculator <br />13) Pencils <br />14) Camera & film (minimum 72 exposures) <br />15) Wooden stakes for hubs and turning points <br />16) Walkie-Talkies (3) <br /> <br />3.3.2 ORGANIZING THE NOTES - The object of the survey is to locate high <br />water marks and cross sections in 3 dimensions. As a result, distance (stadia) and <br />horizontal location (azimuth) from the instrument as well as elevation difference (rod <br />reading) will be recorded. Attachment A, "United States Department of the Interior <br />Geological Survey Water Resources Division Transit Stadia Notes" provides a good <br />system for organizing the slope area notes. <br /> <br />In addition to the notes themselves, a sketch should be made of the cross sections, <br />hubs, turning points, bench marks and reference marks, with the appropriate labels. <br />Remarks should be recorded liberally in the notes and the quality of each high water mark <br />should be rated as excellent, good, fair or poor, depending upon its quality and clarity. <br /> <br />3.3.3 THE SURVEY - Once the high water marks and cross sections have <br />been located and marked, the survey can begin. It is best to use a 3 person party; one <br />on the instrument and two using rods. With 2 rods, shots can be taken on both sides <br />of the stream from one setup, providing tree growth does not block clear shots. <br />Collecting data on both sides simultaneously also allows for checking rod readings <br />against the opposite bank and can help to reduce the chance of gross errors in rod <br />placement Hub and turning point stakes should be left in place until the end of the <br />survey and longer, if possible, in case contradictory data requires points to be re- <br />surveyed. <br /> <br />1-5 <br />
