Table 3 shows the average water
depths and the variability in water depths
(standard deviation) in the three reaches
in 1995 and 1998. In 1995, the average
water depths in Reaches 2 and 3 (beaverdam controlled reaches) were twice the
average depths in Reach 1 (no beaver
dams). In addition, the variability in water
depths in Reaches 2 and 3 was greater
than in Reach 1, indicating more variable
channel bed habitat with possible fisheries
and macroinvertebrate benefits. By 1998,
the dams in the cattle exclosure had either
completely disappeared or were actively
breaching. Water levels were now similar
in all three reaches.
