LAKE ERIE NORTH SHORE WATERSHED PLAN formation. The Lake Erie North Shore study area can be subdivided into 7 sub-cells within this one littoral cell. The following descriptions of the shoreline and sub-cells have primarily been derived from the Lake Erie Shoreline Management Plan (Philpott Assoc. 1992). A reference map follows entitled Points and Bays (Figure 7). The most western sub-cell (No.2; No.1 does not fall within NPCA jurisdiction) in the study area includes the east side of Mohawk Point and Moulton Bay. The east side of Mohawk Point includes bedrock and low glacial drift shorelines, and the remaining of the sub-cell is comprised of two beach dune complexes and a bedrock outcrop at Rock Island where Long Beach Conservation Area is located. Sand dunes in the backshore rise to elevations of 180m. Shore protection along this stretch protects cottages and Lakeshore Road along the lakefront. Littoral sub-cell No. 3 extends from Rock Island to Grabell Point. The bay consists of a beach dune complex in the west that extends 3 kilometres and a short bedrock outcrop that marks the end of this bay at Grabell Point. The shoreline has been fully developed with cottages located on the dune formation, and a variety of shoreline structures protect the cottages along this stretch; however, a few do rely on natural beach protection. Littoral sub-cell No. 4 is formed by two bedrock outcrops; Grabell Point and Morgan‟s Point. A beach is nestled between the two headlands with a texture that varies from sand in some areas and pebbles and cobbles in other areas. No dune development has occurred in this sub-cell. Development covers a majority of the shoreline and an armourstone revetment protects a portion of this shoreline stretch. Littoral sub-cell No. 5 is one of the largest littoral cells in the study area. It extends eastward from Morgan‟s Point to the Welland Canal. Three small headlands interspersed with intermediate bays characterize this stretch of shoreline. The first intermediate bay (Sunset Bay) consists of sand and gravel and is positioned between the gentle bedrock outcrop that marks the base of Morgan‟s Point and Rathfon Point to the east. A variety of shoreline protection structures protect this highly developed stretch of shoreline; at times residences are 3 rows deep from the lakefront. 28
LAKE ERIE NORTH SHORE WATERSHED PLAN Reeb‟s Bay is east from Rathfon Point to the next rock outcrop is (unnamed). The beach widens and consistency is mainly sand with some gravel. Aside from a small portion, the entire shoreline is protected by a number of structures; primarily a seawall. A major dune system occupies the backshore area in this reach. The dune system is lower at the west end, rising to elevations about 180m and to 190m at the east end. The dunes in this area are generally vegetated. Beach access can be obtained by steps that run down the face of the dune. East into the next small bay, the dune system reaches an elevation of approximately 215 metres above sea level (masl), and then drops quickly before reaching the headland of Gravelly Bay. East of the headland, dunes continue to reach significant heights in the western portion of Gravelly Bay, with an elevation of approximately 185 masl. Bedrock is visible along the shore throughout most of the bay. Gravelly Bay marks the western edge of Port Colborne‟s built-up area. Land use in this area consists primarily of residential, commercial and industrial. Due to the presence of the Welland Canal on the eastern end of the bay, this portion of the shoreline is entirely man-made and natural coastal processes have been altered. Numerous shore protection structures are in place to protect the shoreline. Littoral sub-cell 6 is formed by a single bay bordered by the Welland Canal to the west and Cassaday Point to the east; nestled between is Nickel Beach, a well used public beach with widths of over 40m backed by a sandy dune. The wide sandy beach holds dunes reaching elevations of 189 masl. Further east, permanent residences have established on the dunes. Dune formation continues east to the bedrock outcrop known as Cassady Point but drops off rapidly towards the east side of the point. Cassady Point supports the provincially significant wetland and woodlot Nickel Beach Marsh and Woodlot. Extending from Cassaday Point to Point Abino is littoral sub-cell 7. The most western bay in this sub-cell is Lorraine Bay, a gently curved beach bay anchored by Cassaday Point on the west and Pine Crest Point on the east. Widths of this sand and gravel beach vary from 20 to 40 meters and dune heights reach almost 190 masl. The entire shoreline has been developed with residential and seasonal dwellings and protection structures are in place at the top of the beach and the base of the dune. East of Pine Crest Point, a small bedrock outcrop separates the shoreline into 2 small bays; Cedar Bay and Silver Bay. The sandy beaches are separated from the sand dunes that back the beach by a protection structure. Development along the bays is continuous with most of it occurring on top of the dunes. The next eastern stretch of shoreline contains dunes with elevations up to 186 masl. Further towards Shisler Point is one of the few undeveloped extents of shoreline along 29
