Lestijoki

Lestijoki is a river in Finland, located in the Central Ostrobothnia region. It is the longest river in the region, flowing approximately 100 kilometers (62 miles) from its source in the municipality of Toholampi to its mouth in the Gulf of Bothnia at Kalajoki. The river's drainage basin covers an area of about 1,445 square kilometers (558 square miles).

The Lestijoki is characterized by its relatively shallow depth and meandering course, passing through varied landscapes including forests, agricultural land, and wetlands. Along its banks, several smaller tributaries join the main flow, contributing to its overall water volume. The river supports a diverse ecosystem, providing habitats for various fish species, waterfowl, and other wildlife. Historically, the Lestijoki has played a role in local transportation and logging activities.

In the municipality of Kalajoki, the Lestijoki estuary is an important natural area, known for its birdlife and recreational opportunities. The river's water quality is generally considered good, though like many Finnish rivers, it can be affected by agricultural runoff and other human activities. Efforts are ongoing to monitor and protect the Lestijoki's ecological health and natural beauty. The river is a significant feature of the Central Ostrobothnian landscape, valued by locals for its natural and cultural heritage.
