because the water table has reached the surface, bedrock is near the surface so water cannot percolate downwards, or human activity has blocked drainage for the area. Combinations of the three are also possible. The stop at the Indian River (grid reference: 269 118) was simply to collect a water sample for analyzing. The results of the analysis are in Table 1. A comparison of water samples will be made later in this section.The hydrology of the Rice Lake drumlin is very similar to the other drumlins and eskers visited on this day. Well-drained, permeable glacial till comprises the drumlins of the Peterborough area however changes to the drumlins can affect the hydrology. This particular drumlin has been excavated approximately 23 meters from its original peak. Runoff channels are visible on the excavated slopes of the drumlin.Part III: Warsaw CavesInformation of the hydrology at the Warsaw Caves is largely a collection of tests made on a water sample from the Indian River. The results of the tests are included in Table 1 and interpretations and comparisons will be discussed later in this section. Part IV: Comparison of Sites and Previous Literature The entire area this field report is concerned with is part of the Otonabee Watershed. It includes the Indian and Otonabee Rivers that drain south into Rice Lake. These rivers are part of major glacial spillways that are visible by the large, wide river valleys. Barnes (1965, p.136) states that “both the drainage and the drumlins have an almost uniform north-east to south-west orientation, which was the direction of the advance and retreat of the glacier.” The hydrology tests (see Table 1) did not produce any major differences in water characteristics. The most noticeable differences were between dissolved oxygen, chloride, and alkalinity tests of the swamp water from the Bedrock Knob and the Warsaw Caves Indian River water.
