Kings Canyon National Park encompasses the Upper Woods Creek area. Prior to 1973, many of the streams and lakes were planted with trout. This practice had some drawbacks to the native biota such as amphibians. After 1988, all fish planting within the park was discontinued. Park streams and lakes were managed for a sustainable fishery. Those streams and lakes that could not support a fishery were allowed to go fishless. However, by 1990, it was evident that certain amphibians such as the Mountain Yellow Legged Frog (MYLF) had not recovered enough and a management plan was implemented to eradicate certain lakes and streams of non-native fish. By 2013, 15 lakes and ponds were eradicated of fish. Over the next 25 years, the Park intends to eradicate another 70 lakes, streams, and marshes to reach a 15% level of fishless habitat. Most of these fish removals are within the higher elevations of the park and many are fishless due to the unsustainability of fish within these waters due to lack of food source, lack of spawning grounds, and shallow depths lacking winter survival during freezing periods.
From Sawmill Pass you drop into the Upper Woods Creek area of Kings Canyon National Park.
Woods Lake: This 10,800' elevation lake is about 1 mile below Sawmill Pass. Contains Brookies, 8-10 inch range but some up to 13". Most of the smaller lakes surrounding Woods Lake also have Brookies.
Twin Lakes: Taking the PCT north a half miles from the intersection of the Sawmill Pass Trail. Two lakes at 10,600' elevation. Both contain Brookies. Rainbows and Goldens were planted within these water from 1927 to 1964. Netiher could get established due to poor reproductive streams. The smaller Lower Twin Lake has Brookies 7-9 inches whereas the larger and deeper Upper Twin has Brookies 10-12 inches.
Woods Creek: Below Twin Lakes, Woods Creek picks up enough water to support a good population of Golden Rainbow Hybrids., 8-9 inches. There are some deeper holes where the fish can reach 10-12 inches. The White Fork of Woods Creek also holds Golden Rainbow Hybrids but they are somewhat smaller, 6-7 inches.
