Figure 74. Model II (Model in Figure 12) results: Analog
simulations of seasonal variation in fish biomass, fish
density, bird biomass, and bird number under five
conditions of drainage with June 1974 May 1975 rainfall.

 a) primitive (predrainage) conditions
 b) less drained than present
 c) present conditions
 d) more drained than present
 e) maximum drainage conditions

NOTE: See Appendix Table B-1 for mean, maximum, and
minimum acreages of water area under different conditions.
