Results of a comprehensive review of the 

 existing transportation system concluded that 

 roads and recreational use in the Beaver Lake 

 area are the most serious impacts to hydro- 

 logic resources. Due to unmanaged, dispersed 

 recreation and numerous historic access points 

 through private ownership to the north, south, 

 and west, the analysis area has a relatively 

 high road density (2.9 miles per square mile). 

 These factors have resulted in loop roads and 

 road located adjacent to sensitive wetland/ 

 riparian areas, lakeshores, and draw bottoms. 

 In addition, motorcycle and all-terrain vehicle 

 use has created numerous single-track trails 

 located on steep grades. 



In general, the existing transportation system 

 lacks adequate road drainage features and 

 does not meet recommended minimum- 

 standard BMPs. As discussed under the 

 Transportation System section in this chapter a 

 majority of the roads were constructed to icj! J 

 minimum standards for log hauling in the 

 1920s and 1930s. At that time. State policy did 

 not require BMPs. This had a direct influence 

 on the location and standard of roads con- 

 structed in the analysis area during this time 

 period. 



Numerous road segments within the analysis 

 area are identified as high-risk areas to water 

 quality and are listed in Table IV-14 - High-Risk 

 Roads. The sites were identified through
