Green Creek rises near Waller and heads roughly south to Rohrsburg and on to Orangeville, where it joins Fishing Creek. It drains the central part of the Fishing Creek watershed. Little Fishing Creek starts just in Lycoming County near the Columbia County Line. It winds through rural areas before reaching Pennsylvania Route 42, which it runs parallel to for the remainder of its length. It drains the western part of the Fishing Creek watershed. Four covered bridges cross Little Fishing Creek; these are the Wanich Covered Bridge No. 69, the Sam Eckman Covered Bridge No. 92, the Jud Christie Covered Bridge No. 95, and the Creasyville Covered Bridge.
