Summary
Description
The objectives of the aquatic ecology study include an assessment of the fish and aquatic invertebrate populations in the streams and in the ponds throughout the entire year. Most of the work which was to be done on these populations was to be accomplished during the productive or summer months; however, it was necessary to establish observations on these populations during the winter periods. Accordingly, a trip was made in December, 1967, and one in March, 1968, during which both the fish and invertebrate populations were sampled and examined for seasonal variation in terms of both species and numbers.
