Grindstone Creek water clarity : sources and effects / Scott Painter, Lisa Hampson and Karen McCabe.: En13-5/90-15E-PDF

"A spatial survey of water clarity identified in Grindstone Creek has identified that the sources of high turbidity in the delta are predominately the resuspension of silt in the ponds just upstream from the delta and to a lesser extent high chlorophyll concentrations. Water clarity was poorest during May and June despite an eight-week drought during that time period. Upstream Secchi disc depths were consistently greater than 1 m whereas the downstream ponds had a seasonal mean Secchi depth of only 28 cm. The poor water clarity is predicted to limit aquatic plants to only 4 ha and improvements in silt or chlorophyll concentrations could increase plant distribution to 25 ha"--Abstract.
