bank terracing,on the toe armoring and on the in-stream boulders has <br /> significantly increased. I would also like to add the at the drop structures <br /> themselves represent roughly I-2%of the project reach making any sort of <br /> impact—real or implied—insignificant. The only full-depth grouting occurs in <br /> the high velocity portion of the structure which is not used for resting or hiding <br /> areas for fish or invertebrates, significant interstitial spaces exist throughout the <br /> remainder of the structure. <br /> 5. Similarly, Benthic invertebrate production is permanently reduced by grouting <br /> interstitial space in Maroc*substrate. <br /> Answered above. <br /> 6. Impacts to Angling Opportunity: While the change to structures may still produce <br /> fish habitat, there may be a loss offishing opportunity, if the standing wave <br /> produced by the structure is used heavily by boaters. Prhnary use will shift from <br /> fishing to whitewater boating within the dist wind area The San Juan River <br /> through Papua.ESrings supported 2,140 angler days from July to September, <br /> 2001, 53%of anglers were non-residents. This translates to$178,000 <br /> economic benefit for Archuleta County, based on October, 2004 daily expenditure <br /> values!Or angling in Colorado(BBC Research and Consulting). <br /> Mr. I)orsey's assertion that the structure cannot be used by both boaters and <br /> anglers is unfounded. Over 20 similar parks have been constructed in the State or <br /> Colorado, all of which are used by boaters and anglers. Parks such as the Boulder <br /> Creek Park in Boulder, Colorado have been shown to he healthy and active <br /> ecosystems with significant lash populations, significant fisherman usage and <br /> dramatic in-stream recreational traffic. Additionally, angling access has been <br /> improved on the right hank with the addition ofstone terraces and streamside <br /> fishing access points. <br /> As to Mr.Dorsey's suggestion that there will be a net negative economic impact <br /> from these improvements I believe that this is also unfounded. Parks in Vail, <br /> Breckenridv,e,Golden, Steamboat Springs and Salida have nil been shown to have <br /> over a million(sometimes over two million) dollars in economic impact per year. <br /> furthermore, these usage studies also suggest that primary usage of the structures <br /> in Pagosa Springs will he during peak run-off and prior to the dates Mr. Dorsey <br /> mentioned as being peak angling periods. <br /> 7. Impacts to Fishing is Fun(FIF) Gram'(Corps Permit 11199375014) <br /> This issue will be addressed by the City of Pagosa Springs, <br /> 8, Impacts to Other Aspects of Overall River Health, Integrity and User Several <br /> individuals and agencies have expressed concerns about the hydrological impacts <br /> of the work done such as: hardening of the river banks, adding fill into the river <br /> 4 <br />
