The Holland River is a river located in Ontario, Canada. It flows into Cook's Bay, which is the very southern part of Lake Simcoe. The river generally flows north. Its journey starts in the Oak Ridges Moraine, a special area of hills and forests.

The area drained by the Holland River, called its watershed, is about 600 square kilometers (230 square miles). This watershed includes towns like New Tecumseth, King Township, Newmarket, Aurora, East Gwillimbury, and Whitchurch-Stouffville. A very important part of the river's watershed is the Holland Marsh, a super fertile farming area famous for growing lots of vegetables.

How the Holland River Got Its Name

The Holland River was originally known by its Indigenous name, Micicaquean Creek. Later, it was renamed by Lieutenant-Governor Simcoe. He named it after Captain Samuel (Johannes) Holland (1729–1801). Samuel Holland was born in the Netherlands and became the first Surveyor General of British North America. He was a very important person in mapping out new lands.

Who Looks After the Holland River?

The Lake Simcoe Region Conservation Authority is an organization that helps protect the environment. They are responsible for keeping the Holland River healthy and clean. This is because the Holland River is a key part of the larger Lake Simcoe watershed area. Their work helps make sure the river's ecosystem stays balanced for everyone.
