SCA Survey --Major Problems identified in Sligo Creek--

Sligo Creek watershed -Middle Portion 1
We encourage citizens to visit the sites in person in order to see the damage firsthand. Because the stream changes constantly, it may have features differing from pictures shown on this website. Mouse over the numbers in the map below, then click it to enlarge the picture.

001111UC (Unusual Condition) (N39°00.568', W77°00.262')

site #	Date	Description	Potential Cause
001111	4/28/2004	Milky coffee color water	--

Turbid water is coming from a stormwater pipe. These two pipes are the source of Long Branch - one of the tributaries of Sligo. Once a stream is piped, it is very difficult to identify the source of contaminants. See the picture of the site named "turbid" in the map above for the results of this discharge. We should not have piped stream anymore.

Turbid (Unusual Condition)

This highly turbid water came from stormwater pipe (see 001111UC). It is suspected that the water came from construction site; however, we could not identify the source.

023254FB (Fish Barrier) (N38°59.914', W76°59.889')

site#	Date	Blockage	Type	Reason	Drop(In)	Depth(In)
023254	4/23/2004	total	road crossing	too high & too shallow	48	0.5

It is too high and too shallow for fish to go upstream.

023251EP (Exposed Pipe) (N38°59.829',W76°59.872')

site#	Date	Location of Pipe	Type	Diameter (in)	Length (ft)	Purpose	Potential Leak from the Pipe	Color	Odor
023251	4/23/2004	Exposed across bottom of stream	concrete	12	15	sewage	yes	gray	sewage

Two pictures for this site. A crack is in the sewer pipe (see the second picture). According to WSSC, the pipe is lined increasing structural integrity for the pipe.

021105	4/7/2004	Exposed across bottom of stream	smooth metal	--	22	probably sewage	no	--	--

This is also a fish barrier. According to WSSC, this pipe is no longer in service. This will be removed.
