Rock Island Golf Course
Rock Island, Washington · 18 holes · par 72 · Public. Opened 1975.
A caddie's yardage book for every hole: plays-like distance from USGS lidar elevation, reach and carry numbers for every bunker and water hazard, green front, middle and back, which way each green falls, and the lay-up zone on par 5s. Distances are from the back tees along the mapped hole; for a shorter tee, take off the scorecard difference.
Course profile
- At about 620 ft the ball carries about 1% farther than at sea level, so a 150-yard shot plays like about 149. Golfers visiting from low elevation should expect to club down.
- Biggest climb: hole 15, where the green sits 50 ft above the tee and plays about 17 yards longer.
- Biggest drop: hole 1, where the green sits 43 ft below the tee and plays about 14 yards shorter.
- 12 greens tilt 2% or more. Each hole below says which side of the hole leaves an uphill putt.
Maps: tee at the bottom, green at the top. The dashed line is the mapped hole; the gold band is the lay-up zone; the arrow on the green points downhill.

Hole maps, hazards and playing notes come from mapped course data and USGS 3DEP elevation (public domain), not a visit. Plays-like numbers use the Skitty caddie's rule of one yard per 3 ft of rise, from the longest tee; altitude uses 1.16% of carry per 1,000 ft. Tees, hazards and conditions change; check with the course before you play. Map data © OpenStreetMap contributors (ODbL 1.0) via OpenGolfAPI. Scorecard yardages and ratings as published.
