reconstructed, and repaired by segments during different periods over the past 
117 years. In general, the north side shows accretion while the south side 
shows accretion from the breakwater to about 1,200 feet south and then general 
erosion farther south. 
The following areas (Fig. 12) appear to be affected by the navigation struc- 
tures as evidenced by aerial photos, condition surveys, and plat maps for the 
period of record (1849 to 1945): 
(a) North of Holland Harbor (Eaglecrest Road to the North Pier of 
Holland Harbor). It is considered that the accretion fillet north of 
the piers has been relatively stable since 1933. After that date, the 
predominantly southward-moving littoral drift has been diverted lake- 
ward resulting in rising nearshore elevations north of the breakwater 
and deposition of material in the entrance channel. This reach of 
shoreline, about 5,000 feet in length, is characterized by increasing 
accretion from north to south (Fig. 12, reach 1). 
(b) South of Holland Harbor. 
(1) Holland Harbor entrance channel to a point 200 feet south 
of the Ottawa-Allegan County line (Fig. 12, reach 2). Reach 2 extends 
about 2,000 feet south of Holland Harbor, and consists of a sand beach 
about 50 feet wide backed by low sand dunes. The shoreline adjacent to 
the south pier accreted at the rate of 9.6 feet per year from 1871 to 
1944, a total of 700 feet. This area of accretion diminishes progres- 
Sively southward from the piers to a point 200 feet south of the county 
line where the shoreline before major construction (1871) coincides 
with that of the 1929 and 1944 surveys. 
(2) From 200 feet south of the Ottawa-Allegan County line to 
147th Avenue (Fig. 12, reach 3). This reach is about 2,400 feet in 
length and is characterized by high, stabilized sand dunes (up to 120 
feet above low water datum) which are being undercut by wave action.
