Crane Creek Pool 2A Survey Points

Listed in NASA Earthdata CMR

This data set contains all of the elevation points used to model the ground surface in Pool 2A at the Ottawa National Wildlife Refuge.

Description

Over 95% of the original wetland habitats along the U.S. shoreline of western Lake Erie have been lost since the 1860s. Most of the remaining coastal wetlands have been isolated by earthen dikes and no longer provide many of the functions of coastal wetlands (e.g., fish habitat).

Unfortunately, most of the few remaining undiked wetlands are severely degraded. They remain hydrologically connected to the lake, but the wetland vegetation that provides vital fish habitat is sufficiently degraded to negatively impact the approximately 43 species of Great Lakes fish that use wetland habitats. The 2003 EPA project initiated the restoration of the drowned-river mouth wetlands at Crane Creek, a small stream flowing into western Lake Erie.

Since historical descriptions of the study site suggest a much broader expanse of wetlands than just the 345 ha (852 ac) in and near the Crane Creek channel, the diked wetlands bordering the creek were examined to evaluate options for long-term ecological restoration. The research focused on both reestablishing wetland vegetation near Crane Creek and exploring whether diked wetlands can be functionally restored by hydrologically reconnecting them to Lake Erie, effectively adding habitat to the lake.

This work addressed many of the high priority research areas identified by the 1998 EPA Science Advisory Board report on marsh management and restored critical coastal wetland habitat, identified as a special focus area in the Great Lakes Strategy and recently identified as a priority by the Council of Great Lakes Governors. One aspect of this research was to characterize the bathymetry and topography throughout the wetland complex.

This data set was used to generate a topographic/bathymetric surface that will allow modelling of different biotic and abiotic conditions.
