Improved protection for the White Clay Creek Watershed is being considered in Senate Bill 853, a proposal  to expand White Clay's 2000 National Wild & Scenic River designation. The two small stream sections originally omitted from the White Clay's designation are surrounded by designated watershed.  The additional nearly 10 stream miles they represent would bring the total number of designated stream miles to 199.9.  Ten years of the program's accomplishments accompanied by changes in anticipated usage of the creek led to requests for inclusion of these areas.

The 1.6 miles of Delaware's Lamborn Run, stretching almost from the headwaters to the mainstem of White Clay Creek, had originally been omitted.  It had been considered as an option for a dam to provide water supply for northern Delaware. In July of 2008, the Delaware River Basin removed it as a water supply option since other supply options had been pursued (Hoopes reservoir deepening and City of Newark's off-stream reservoir).  So the Management Committee sought inclusion of this heavily wooded stream valley, which runs through the White Clay Creek State Park and a very small section of private property.

The Management Committee then asked Pennsylvania's New Garden Township if they also might want to seek inclusion of the 7.4 undesignated stream miles within the township's boundaries. This section was originally omitted in part because the township thought they too might consider damming of a tributary for future water supply, and partly because they were unsure of the impact of designation.  But as the years have passed they realized a dam was neither necessary nor a good idea.  The local community also witnessed the advantages other townships were enjoying because of Wild & Scenic River designation.  So the township's Board of Supervisors voted to request Egypt Run and the missing section of the East Branch also be included in the congressional bill to expand the National Wild & Scenic River designation for White Clay Creek.

S. Bill 853 was introduced by Delaware Senator Edward Kaufman, partly as a legacy to now Vice President Joseph Biden, and cosponsored by Delaware Senator Thomas Carper and Pennsylvania Senator Robert Casey. If successful S. Bill 853 will provide more comprehensive protection of the White Clay Creek Watershed.
