Based on the assumptions described in the introduction why might the mark and recapture method of population estimation be more accurate in the lake setting we are studying than in a stream or river

In ecology, the mark and recapture method is utilized to predict the population size of the animals. In the method, the part of the population is caught, marked, and then discharged. Afterward another part is caught, and the number of marked organisms within the sample is measured.  

The mark and recapture method of predicting the population is more precise in the setting of lakes as a lake is a fairly steady environment, while the streams and rivers are in motion, and thus the population is much more dynamic.
