200, 10-11" Rainbow trout stocked in April 2006
Have grown to 16" inchers!
2 weeks ago- lost 7 trout- 3 floaters, 4 sinkers
in a 4 day period following 1.33 inches rain on one day and .7" the next (according to web weather, as I live 130 miles away!)
Water was much murkier when I arrive and found the dead trout than is typically. Since excavation- we are getting some sand / soil erosion during heavy rains like this

QUESTION:
How sensitive are rainbow trout to muddy water / suspended soils in the water? I have zero knowledge base on this issue. Anyone out there who knows about this??
