Chlorophyll-carrying capacity (as |g chla L-1) of water columns as a function of the depth to which they are mixed (hm) and the background coefficient of light extinction due to colour and suspended tripton (sw + Sp). Solutions assume that Pmax/R = 15 and day length is 12 h. Redrawn with permission from Reynolds (1997a).

a 10-m layer to ~20 mg chla m-3 in a 40-m mixed layer and to <1 mg chla m-3 in a layer mixed to 80 m. Steel and Duncan (1999) developed a similar model to emphasise the advantages of destratifying the eutrophic Thames Valley Reservoirs supplying London in order to lower their plankton carrying capacity below that of the nutrients.
