Glen Park Falls

Just below the Glen Park Dam. 

Easily portaged by going to the right of the dam. There is an obvious path that the commercial rafting companies use. Follow the trail all the way down to the fish ladder or rock scramble back down to put in for Three Rocks. 
If you choose to run Glen Park Falls you'll want to head left. Often you'll have to wait for the water to "turn on," which is a good opportunity to scout the last drop for debris that likes to collect there. Glen Park Falls can be run several ways but best to avoid being munched by the hole at the bottom.

Locals gauge the flow by checking out the square on the dam. When the square is 1/3 covered it is runnable but scrapy; 1/2 covered is ideal ; 2/3 covered it starts to get pushy. Generally a 1/2 covered square is about 2000 cfs going through the canyon.
