 Trenchards Inlet (Map 5) 



119. From 1859/60 to 1920/21, the updrift side of Trenchards Inlet grew 

 southwest about 730 m, at an average rate of 13 m/year. The downdrift side 

 eroded in response as the inlet throat decreased in width only slightly 



(60 m) . By 1955, the updrift shoreline had receded northeast over 1,030 m, 

 putting it landward of the 1859/60 position. Throat width remained constant, 

 and only minor changes occurred on the downdrift side. Shoreline recession 

 was evident along Capers Island throughout the time span. Erosion of the 

 updrift spit continued until the 1982/83 survey, having moved northeast an 

 additional 7 m/year since 1955. Surface area of the updrift spit on Capers 

 Island had increased 3 . 3 x 10 6 m 2 between 1859/60 and 1920/21 (54,000 m 2 / 

 year), but lost 7 . x 10 6 m 2 by 1982/83 (111,000 m 2 /year) . 

 Pritchards Inlet (Map 5) 



120. Two tidal creeks intersected at the shoreline in 1859/60 forming a 

 "V" shape with the point of the "V" seaward. The single inlet formed from 

 these two creeks is Pritchards Inlet. Constant landward erosion until 1955 

 resulted in removal of the base of the "V" and intersection of two separate 

 inlets within the shoreline. In 1859, distance between opposite sides of the 

 inlet was about 425 m. By 1955, it had grown to 1,000 m. In 1859, distance 

 from the land inside the "V" to the shoreline trend was about 240 m. With the 

 pattern of erosion described, this center section was cut back approximately 

 180 m so that by 1983, the gap between inlets had a receded shoreline of only 

 60 m. The largest change came between 1859/60 and 1920/21, when the updrift 

 side of the inlet retreated northeast about 270 m and the downdrift side 

 retreated westward 120 m. Since 1920, updrift and downdrift spits have been 

 small, both showing a maximum alongshore extension in 1971. 



Skull Inlet (Map 6) 



121. In 1859/60, Skull Inlet had a east-west orientation at its point 

 of juncture with the shoreline. Updrift accretion and erosion downdrift have 

 resulted in a nearly north-south orientation on the 1982/83 survey. Much ero- 

 sion and accretion was accomplished between 1856/59 and 1920. The downdrift 

 side was eroded approximately 185 m alongshore during this interval while the 

 updrift side accreted approximately 890 m. The inlet throat narrowed consid- 

 erably, from 1,030 m wide to about 245 m. Since 1920, throat width decreased
