Trip Description:

DDRC will be lending a hand to the TCRA and TRPA to help clean up the San Marcos River on Saturday February 27 th. We will be camping at Shady Grove Campground (FM 1979 and the river in Martindale) on Friday and Saturday nights. We will drive down and camp Friday night. The river cleanup will be Saturday starting at 8:30 AM. Dinner is provided at Shady Grove for all cleanup volunteers on Saturday evening.

This reach of the San Marcos contains a a few small rapids and rock gardens, the Rio Vista whitewater park, two dams to portage, Cottonseed Rapid (FUN at the current level) and a lot of scenery. Difficulty can range from Class I to Class III, but most of it will generally be Class II to easier. Fiberglass, Kevlar, carbon fiber or any other fragile material boats would not be recommended for this trip. The river flows through heavily vegetated banks and adjacent farmland with very little commercial development even though you are never far from a major road or civilization.

Sunday, we will have a short paddle before heading for home 


Gear Requirements:

Bring boats rated for up to Class III whitewater, PFD's (lifejackets), paddles (a spare is recommended), a whistle or other signalling device, throwbag, tent, ground pad, sleeping bag, clothing for hot, cold, wet and dry conditions, camp chair, headlamp, plate(s), flatware, drinking cup, personal toiletries and other items that you may want to have with you. A small cooler for drinks and lunches to be carried in your boat would be recommended. Members of the group should coordinate on community gear such as cookware, stoves, fuel, charcoal and other such items.


Bring your own meals. Diner is provided at Shady Grove for cleanup volunteers on Saturday evening.  Bring plenty of beverages, but remember - NO GLASS OR FOAM POLYSTYRENE STYROFOAM CONTAINERS!

* International Scale of River Difficulty

Class I: Easy. Fast moving water with riffles and small waves. Few obstructions, all obvious and easily missed with little training. Risk to swimmers is slight, self-rescue is easy.

Class II: Novice. Straightforward rapids with wide, clear channels which are evident without scouting. Occasional maneuvering may be required, but rocks and medium sized waves are easily missed by trained paddlers. Swimmers are seldom injured and group assistance, while helpful, is seldom needed.

Class III: Intermediate. Rapids with moderate, irregular waves which may be difficult to avoid and which can swamp an open canoe. Complex maneuvers in fast current and good boat control in tight passages or around ledges are often required; large waves or strainers may be present but are easily avoided. Strong eddies and powerful current effects can be found, particularly on large-volume rivers. Scouting is advisable for inexperienced parties. Injuries while swimming are rare; self-rescue is usually easy but group assistance may be required to avoid long swims.

Class IV: Advanced. Intense, powerful but predictable rapids requiring precise boat handling in turbulent water. Depending on the character of the river, it may feature large, unavoidable waves and holes or constricted passages demanding fast maneuvers under pressure. A fast, reliable eddy turn may be needed to initiate maneuvers, scout rapids, or rest. Rapids may require "must" moves above dangerous hazards. Scouting is necessary the first time down. Risk of injury to swimmers is moderate to high, and water conditions may make self-rescue difficult. Group assistance for rescue is often essential but requires practiced skills. A strong eskimo roll is highly recommended.

Class V: Expert. Extremely long, obstructed, or very violent rapids which expose a paddler to above average endangerment. Drops may contain large, unavoidable waves and holes or steep, congested chutes with complex, demanding routes. Rapids may continue for long distances between pools, demanding a high level of fitness. What eddies exist may be small, turbulent, or difficult to reach. At the high end of the scale, several of these factors may be combined. Scouting is mandatory but often difficult. Swims are dangerous, and rescue is difficult even for experts. A very reliable eskimo roll, proper equipment, extensive experience, and practiced rescue skills are essential for survival.

Class VI: Extreme. One grade more difficult than Class V. These runs often exemplify the extremes of difficulty, unpredictability and danger. The consequences of errors are very severe and rescue may be impossible. For teams of experts only, at favorable water levels, after close personal inspection and taking all precautions. This class does not represent drops thought to be unrunnable, but may include rapids which are only occasionally run.
