NonPoint is software that accompanies the report by Carpenter et al. (1999). NonPoint models the dynamic interactions between a lake ecosystem subject to nonpoint pollution and a social system that depends on the lake. Actors in various simulations include scientists, economists, regulators, farmers, soils, lakes- and you, the game player. The three models described by Carpenter et al. (1999) are included here: Market Manger, Governing Board, and Land Manager models.
