both riversides (see Map 2). It was only pos-
sible to have 6 stations at one river in each
area; this was because it was not desirable to
come too close to inhabited areas. We did
not want our formalin containing traps to be
near playing children. The lowest altitude
used was 6 m and the highest was 250 m. In
the OD and ND area one station was placed
right above the intake, one right below the
intake, and then at certain distances (50m al-
titude) downwards, as far down as possible.
The same was done in the UD area but here
stations were above and below planned in-
takes. Intakes refers to the place in the river
where SEV takes the water or plans to. At
each station we placed 5 pitfall-traps at 1 m
distance in a line outwards from the river-
bank; this was done on both sides of the
river, see Table 1 and Map 2. The traps were
intended to reveal if there was any difference
between places where SEV has taken the
water and not. The season was July and Au-
gust 2007, during which pitfall-traps were
emtied regularly (every 2 to 3 weeks), though
