The village is where the infant
River Colne is joined by a stream from near
Stambourne and another that has flowed via
Toppesfield. The river flows through
Colchester on its 39-mile journey to the
North Sea. From the 1950s to the 1970s, Great Yeldham was home to the Whitlock Bros., an agricultural equipment manufacturer. In 1972, Whitlock Bros. was taken over by Hymac and production subsequently moved to
Rhymney in South Wales; the plant closed, resulting in many job losses. The land around Great Yeldham is used principally for arable farming and some livestock rearing. From the early 1950s until the mid-1980s, it was also known for Lark Hill Farm, its apple and strawberry farm. ==Transport==
