Pigeon River (Ottawa County, Michigan)

The Pigeon River is a small river flowing to Lake Michigan on the western Lower Peninsula of the U.S. state of Michigan. The river is approximately 12.9 mi long and drains an area of 61.7 mi2  in a generally rural area situated between the cities of Holland and Grand Haven. Via Lake Michigan and the larger Great Lakes system, it is part of the watershed of the St. Lawrence River.

Course
The Pigeon River's watershed and course are located entirely in western Ottawa County. The river is formed by a confluence of agricultural drainage ditches in Olive Township and flows generally west-southwestward into Port Sheldon Township. After flowing through Pigeon Lake, which is the only lake in the river's watershed, it flows into Lake Michigan in Port Sheldon Township, approximately 9.5 mi northwest of Holland and 11.3 mi south of Grand Haven.

Two county-operated public parks, Pigeon Creek Park and Hemlock Crossing, are located along the lower course of the river. The river has been stocked annually with brown trout by the Michigan Department of Natural Resources since 2003.

Watershed characteristics
The Pigeon River watershed is located in portions of seven townships of Ottawa County:

Formerly covered by forests and wetlands including a black ash swamp that covered 75% of the watershed, by the 1920s most of the watershed had been cleared and drained for agriculture. Portions of the watershed were reforested in the 1940s to control wind erosion. A 1997 watershed management plan found that approximately half of the land in the Pigeon River watershed was used for agriculture, with most of this area in Blendon, Olive, and Robinson townships. Agricultural production in the watershed included ornamental nursery crops, Christmas tree, blueberries, upland vegetables, field crops, turkeys, poultry eggs, beef and dairy cattle, and hogs.

Land use in the watershed as of 1992 was as follows:
