Incidental observations of amphibians, reptiles and mammals were recorded while
conducting other field surveys. Green Frog (Rana clamitans) and Bullfrog (Rana
catesbeiana) were heard calling from wetlands on the margins of the beaver pond and
adjacent to Thompson Creek. One Snapping Turtle (Chelydra serpentina serpentine)
was observed on the margins of the beaver pond and a Midland Painted Turtle
(Chrysemys picta) was observed laying eggs in an old-field meadow on the south side
of Thompson Creek. One Eastern Gartersnake was observed in a willow thicket swamp.
Beaver dams and lodges were observed downstream of the beaver pond and one Beaver
(Castor canadensis) was observed swimming in the pond. A Muskrat (Ondatra
zibethicus) was observed in Thompson Creek downstream of the Trent Canal dam and
two White-tailed Deer (Odocoileus virginianus) were observed in deciduous forest and
old-field meadow.

3.3.3 Fluvial Geomorphology
During the current study, a Rapid Geomorphic Assessment (RGA) survey was
completed of Thompson Creek from its confluence with the Otonabee River to the
Thompson Creek Dam. The water course were divided into a series of four
representative reaches for evaluation purposes. A total of nine cross-sections were
chosen to represent those four reaches. Figure 3.3.5 shows the extent of each reach and
the nine sampled locations. Typical conditions in each reach are shown in a series of
photographs in Photographs 3.3.1 to 3.3.6 at locations which are referenced on
Figure 3.3.3. The detailed results are included in Appendix F. Table 3.3.3 summarizes
the geomorphic parameters for each of the sampled locations. A detailed description of
the habitat and stream conditions was provided in Section 3.3.1 and Appendix D.
