from the BLM doc... why they did not choose upstream locations. Looks solid and practical to me. Also note that upstream of launch 1 up to inspiration point site is prime spot for fisherman. Especially in shoulder seasons, there are lots of them up there.
Alternative 2e Inspiration Point:
Alternative 2e at the Inspiration Point is located approximately 2,000 ft upstream of Pumphouse Boat Launch 1. Similar to all potential in-channel sites, Alternative 2e was evaluated for opportunities and constraints associated with the construction of whitewater features. Challenges identified at this site included reduced proximity to commercial areas, restricted parking capacity, no existing facilities and significant construction costs mostly associated with improving the very steep existing 4WD drive road that accesses the site and installing parking and facilities in existing disturbed areas.
Alternative 2c Upstream of Pumphouse Launch 1:
The site is approximately 1,000 feet upstream of the upper most boat launch (Launch 1) and was evaluated and determined to have challenges associated with no water rights applied for or appropriated, appropriate concentrated use, reduced proximity to commercial areas, competing uses, existing disturbances, habitat sensitivity, disturbance footprint, and construction access. Though this site offered many advantages, constraints associated with the location upstream of Launch 1 led to a determination of lesser value.
Environmental impacts upstream of Launch 1 were primarily related to temporary construction access and staging as well as long term access to the feature. This site sits downstream of Gore Canyon within a relatively steep pool riffle sequence. Construction of a river recreation enhancement feature midway up the riffle would require the construction of an approximately 1,000 ft long access road to be built on river left through a well-developed low lying riparian wetland. Staging at the site would also create significant temporary impacts to the riparian zone on river right. Because this location does not currently have access other than an unimproved foot 8
path and it sits at the mouth of Gore Canyons Class V-VI rapids, minimal shore traffic affects the quality of the existing riparian habitats.
Alternative 2c has fair proximity to existing facilities and use benefits as it is upstream of a developed boat ramp, parking, bathrooms and picnic area; however, the significant riparian zone posed greater habitat sensitivity. This site had a relative score of 70 as presented in Table 1.
