The Chairman. Class I streams includes any natural freshwater 

 body of water containing anadromous fish or high value resident 

 sports fish. 



Dr. Koski. We will be able to add wording for legislation at a 

 later time if you like. But also, let me comment on that. 



In our definition of Class II streams, the proper buffer zone re- 

 quirements would be that any Class II stream which runs or drains 

 into a Class I would require a minimum 100-foot buffer zone. 



Now, that excludes all those Class II's that dump directly into 

 the sea or the ocean. The purpose again is to ensure maintenance 

 of downstream habitats, the preservation of water quality prevent 

 sedimentation, but maintain dissolved oxygen, temperature, et 

 cetera. 



The Chairman. Well, what do you do with Class II that drain 

 into the ocean? 



Dr. Koski. That is what I am saying. You may be misinterpret- 

 ing me. 



The Chairman. No protection for them, or leave it to the Forest 

 Service? 



Dr. Koski. The Class II's that dump directly into the ocean, what 

 we are requiring is that the Forest Service utilize their best man- 

 agement practices, which require the maintenance of water quality 

 standards. 



The Chairman. And if they go into the anadromous fish 

 streams? 



Dr. Koski. If they go into a Class I stream, then we would re- 

 quire minimum 100-foot buffer zones. And there really are not that 

 many Class II's in the forest. It is kind of a unique situation. They 

 are either at the head of the watershed or they are in areas which 

 Dr. Brooks is referring to with blockages and only have limitations 

 to our resident species. 



The Chairman. In Class III? 



Dr. Koski. Class III streams, Class III streams are those streams 

 which are only important from the stance of water quality. There 

 are no fish utilizing these systems. 



The Chairman. How do you suggest we protect them? 



Dr. Koski. We would like to protect those streams. Those Class 

 III streams also running, draining into a Class I, should require a 

 100-foot buffer zone. Now, there are exceptions to that in that those 

 streams 



The Chairman. Same rule with Class II? 



Dr. Koski. Same rule as with Class II. 



Class III streams are typically your alpine, high mountain 

 streams, and many of those streams are ephemeral, are intermit- 

 tent or storm channels. They only flow in extremely high rains or 

 storms. 



In the majority of cases those streams do not need the 100-foot 

 zone. They need BMP's, best management practices. 



The Chairman. Even if, what if they flow into a Class I? 



Dr. Koski. Regardless, they only need best management prac- 

 tices. If they are very high gradient, over eight percent, if they are 

 ephemeral or intermittent, and they only flow during storm condi- 

 tions, they do not require a 100-foot buffer.
