ISRP final recommendation: Not fundable


This project is a duplication of studies proposed by the Confederated Tribes of Warm Springs Reservation of Oregon in the Deschutes River, except that the Fifteenmile Creek basin work deals more with habitat degradation problems. Because most of the objectives are similar between the two proposals it would be more effective if the studies were focused on the Deschutes because it is uncertain if the lamprey habitat can be recovered in Fifteenmile. For these reasons, the ISRP believes this project is not fundable at this time. While the CBFWA Lamprey Technical Working Group is mentioned, there is no indication that the TWG has identified the objectives of this proposal as fitting into an overall plan or strategy for determining basic information on lamprey. It should be possible to generalize from results of existing studies – if this is not so the proponents need to point out the absolutely unique attributes of Fifteenmile. The habitat in the Fifteen Mile Subbasin appears to be in very poor condition. Lamprey habitat is suffering from multiple habitat stresses ranging from toxic spills to impassable conditions owing to culverts. Although the proposal was well written, insufficient data were provided on some of the degradation to determine if some features were recoverable, especially water quality. For example the specific type of toxic spill was not identified – is the stream still suffering from chronic effects of it? Although the proponents must feel lamprey habitat in the creek can be recovered, it was difficult to get a perspective on how realistic this goal actually would be.
