Shown are the seasonal averages and overall seasonal averages of biomass for the individual streams as well as the characterized streams. Seasonal average is the average of the four streams for a particular season. Overall seasonal average is the result of averaging the seasonal averages to compare agricultural, forested, and urban streams through the seasons. 26
Factors Affecting Perlphyton Growth Appendices F and G list the monthly averages for each parameter monitored; total phosphorus (T-P0 4 ), nitrates (N0 3 ), chlorides (GI), turbidity (TRB), velocity (VEL), and temperature (TMP) in all the streams during the year. The yearly average of the parameters for each stream is shown in Table 2. Stream 2 had the highest concentrations of T-P0 4 (.334 mg/l) and CI (33.42 mgtl) as well as the highest TRB average (396.48 ntu) during the year. Stream 17 had the highest concentration of N0 3 (1.55 mg/l), stream 15 had the highest average VEL (2.26 m/s), and stream 16 had the highest average TMP (12.15 QC) during the year. Stream 1 had the lowest yearly averages of T-P0 4 (.020 mg/l) and TRB (3.76 ntu) measurements during the year. Stream 5 had the lowest yearly averages of N0 3 and CI concentrations (.22 and 3.80 mg/l, respectively). The lowest yearly average VEL was in stream 20 (.97 m/s) and stream 9 had the lowest yearly average TMP (9.22 QC). Tables 3b, 3c, and 3d show the seasonal averages of the T-P0 4 , N0 3 , CI, TRB, VEL, and TMP measurements during the year between the agricultural, forested, and urban streams. For each parameter the seasonal averages in the individual streams, seasonal averages for the streams during each season, and the overall seasonal averages for these streams are given. In Table 3b, the highest seasonal averages of T-P0 4 were during winter in the agricultural streams (.068 mgtl) and during summer in the forested streams (.047 mg/l) and the urban stream (.680 mg/l). The lowest· seasonal averages of T-P0 4 were during spring in the agricultural streams (.045 mg/l), fall in the forested streams (.026 mgll), and winter in the urban stream (.095 mgtl). The 27
