    sampled in the WCC watershed White Clay Creek The watershed is a combination of forests 22 agriculture 51 and development 13 Land use is variable in the watershed but mainly rural agriculture in PA and mostly suburbanized homes and industry in DE Analyses indicated Good water quality in the headwaters but as the watershed becomes larger water conditions became more degraded corresponding to an increase in impervious surfaces e g parking lots and roads and developed areas e g buildings Poor water quality conditions in the Lower Mainstem of WCC should not be attributed solely to changes in land use since water quality is Poor below the East West and Middle Branches including sites in the forested State Parks before it ever reaches the heavily populated and developed area of Newark DE WCC Schuylkill Watersheds An analysis of WCC sites and sites in the Schuylkill watershed showed that more forests and less agriculture in the watershed resulted in higher water quality In the Schuylkill watershed there is a clear relationship between forest agriculture and water quality but this pattern is less clear for the WCC watershed Contrary to expectation some of the best water quality sites in WCC have the highest percentage of agriculture and lowest forest The relationship between population density and MAIS also differs between watersheds water quality is much more degraded in the WCC watershed compared to the Schuylkill for a given population density Land use and MAIS scores for Stream Watch sites 1 12 yrs of data in WCC and 138 sites in the Schuylkill Sch watershed 1 14 yrs of data R2 show the strength of the relationship between the MAIS scores and land use variable for Schuylkill and WCC sites i e the closer to 1 0 the stronger the relationship See report for

    1991 to 2008 In addition several sites in the Avondale area were sampled in 2005 The macroinvertebrate data were used to calculate a Macroinvertebrate Aggregated Index for Streams MAIS that integrated various types of information into a single number that classified streams as Good Fair or Poor Of the 18 long term monitored sites only one Site 11 was classified as Good 9 sites were Fair Sites 12 0 3 4 7 19 17 24 23 and 8 sites were Poor Sites 25 18 16 6 14 20 21 22 The most upstream sites Sites 11 0 19 scored higher than sites downstream on the same branches All three branches of the upper White Clay had sites in the Fair and or Poor category and all sites on the Lower Mainstem were Poor indicating degraded water or habitat quality PA DEP and DNREC also consider water quality in WCC as impaired based on their 303 d list Map of sites sampled in the White Clay Creek watershed from 1991 2008 Stream condition was rated using benthic macroinvertebrates which are a widely accepted tool in water quality monitoring programs The exact cause s of degradation at various locations in WCC are not known but often stream degradation can be linked to the human uses of water and land Land use is variable in the watershed but mainly rural agriculture in PA and mostly suburbanized homes and industry in DE As the watershed becomes larger moving downstream water conditions become more degraded corresponding to an increase in impervious surfaces parking lots and roads and developed areas buildings It is important to recognize that water conditions are Poor in the Upper Branches in PA before it ever reaches the Lower Mainstem Therefore Poor conditions in the lower half of WCC should not be attributed solely to local land use changes or an increase in population density Data from sites in the East West and Middle Branches showed that as the number of people and the amount of developed land in the watershed increased the water quality decreased Sites on the East Branch suggest that water quality degrades in the vicinity of Avondale Land use changes and point source discharges that occur in this area include the increased population density of the borough a golf course the wastewater treatment plant and other non point sources e g residential areas and agriculture including mushroom facilities The East Branch remains poor south of Avondale and even with the addition of the West and Middle Branches which were mainly rated as Fair the main channel remains Poor The large forested areas in the state parks in PA and DE also do little to improve the water quality of the Lower Mainstem through Delaware Apparently in this case large forests do not correct stream degradation that begins upstream Further studies may want to ascertain the specific influences that are negatively impacting the East Branch and propose suggestions for their remediation or prevention Compared to 150 sites in the
