Macroinvertebrates were sampled on a regular basis from March to October
1973. A relationship between chironomid length and biomass was established.
Production equations to be used for these insects are reported. A similar
length/weight relationship is presently being explored for the oligochaetes.
A proposal is made for calculating their production as well as for sphaerids
and P. affinis. Sampling is expected to continue at least through March
1974 to give a full year's data. In the near future the results of this
study are to be correlated with studies concerning primary production,
fish feeding habits, lake sedimentation rates, and physical properties
