Green Valley Lake is used for all types of boating; water skiing is allowed in a designated area. For safety reasons, there are special regulations governing water skiing. All other boats must keep out of the general traffic pattern of boats pulling skiers and must not operate at speeds greater than five miles per hour when within 50 feet of another craft or person. All water skiers, including those using surfboard-type devices, must wear U.S. Coast Guard approved life-saving jackets. No boat is allowed to be operated within 100 feet of shore at speeds greater than five miles per hour. Boats must also maintain a "no wake" speed when outside the ski zone. Four boat ramps on Green Valley Lake provide convenient lake access.

Green Valley's 390-acre lake draws hundreds of visitors on hot summer days. Not only does it offer excellent fishing, boating and swimming, it is also the focal point for a great variety of other outdoor recreation pursuits.

Facilities and Activities

Picnicking/Shelters

The 3 rustic pine log camper cabins offer visitors a sense of pioneer lifestyle. The cabins have electricity, a covered porch and basic furnishings.

Trails
A new 3.5 mile paved trail starts in the campground, bordering much of the east side of the lake, and finishes near the Green Valley Lake Dam. The paved trail connects with 3 miles of other paved trails south of the lake that travel through MItchell Marsh Wildlife Management Area, past Southwestern Community College, and ends at McKinley Lake City Park in Creston. Other grass multi-purpose trails, many bordering the lake, provide visitors excellent opportunities to investigate remote areas of the 1,060-acre park and enjoy its wildlife and plants.

The swimming beach is a great place to cool off on a hot summer day for both kids and grown-ups. Green Valley has long been a popular "fishing hole" for both bank and boat anglers. A number of fishing jetties are available.
