Crooked Creek & Burnt Mill Creek Sample Trip 12.03.09

These photographs were taken during a sampling trip on December 3, 2009.  This is what Crooked Creek looked like after approximately 6.20 inches of rain fell in the area of the construction site at the new Panama City - Bay County International Airport.  A stormwater pond was overtopped during the rain event and the muddy water from the pond is being discharged directly into Kelly Branch, a major tributary of Crooked Creek. Turbidity in Kelly Branch was 125 NTU's*.

*NTUs = nephelometric turbidity units.  A unit measuring the lack of clarity of water. Water containing 1 milligram of finely divided silica per liter has a turbidity of 1 NTU. Rainfall was obtained from the Florida Division of Forestry at Pine Log Forestry Tower (Chipola District).

Crooked Creek Sample Trip 09.19.09

The following photos were taken during a sampling trip on Crooked Creek on September 19, 2009. Cumulative 7-day rainfall prior to this trip was 2.10 inches at Pine Log Forestry Tower. Highest turbidity measured during this trip was 13.2 NTU's in Kelly Branch.  The muddy water may have been the result of ongoing "silviculture" activities which involved the excavation of portions of Kelly Branch under a forestry authorization permit for ditch maintenance.
