Water Quality (12/30/2015 & 1/8/2016)

High-intensity chaparral fires cause increased erosion and sediment transport into streams, and this can be seen in the thick black sludge filling the Cold Creek channel.  On my December visit, with no recent rain, the creek bed was pretty dramatically full of sludge.

By my January visit, several small storms had contributed to small flows in the creek.  As water washes the runoff from the burned hillsides through the system, ash from the fire as well as contaminants that were present on the hillsides will move through Cold Creek and into Putah Creek.  This creates water quality concerns which will be addressed by future water quality monitoring to be conducted by the Solano County Water Agency.
