3.2.1.1.2 Analysis Method 



The following section contains the existing conditions analysis methods 

 for the geology, soils, watershed, hydrology, and fisheries portions of the 

 Fish Creek Salvage Environmental Assessment. This analysis includes an 

 existing condition assessment of the watersheds draining the proposed sale 

 area. The assessments are based on a coarse filter screening approach, 

 reference to Burned Area Emergency Rehabilitation (BAER) fire 

 assessments, and an on-site field review of State lands, stream channels, 

 and access roads in the proposed salvage area. 



DNRC was involved in surveys of fire severity mapping and 

 reconnaissance surveys of the burned area. Surveys to assess risk of 

 potential erosion and storm damage following the fire were completed 

 with particular attention focused on areas of high and moderate bum 

 severity, steep slopes, and roads. Soils were evaluated for bum severity, 

 hydrophobicity (water repellency from buming), potential for natural 

 revegetation, and landslide and erosion potential. Bumed riparian areas 

 and streams were reviewed and evaluated for anticipated affects to 

 downstream fisheries. Stream crossing culverts were inspected for 

 evidence of recent flow, culvert size and capacity, condition, and extent 

 and severity of bum in the contributing watershed. 



Information for the fisheries assessment was also based on a review of the 

 Montana Natural Information System MFISH stream records for fish 

 surveys, relevant peer reviewed literature, data, and habitat records from 

 the Lolo National Forest, Montana Department of Fish, Wildlife and 

 Parks, and personal communication with local agency experts. 

 Reconnaissance field reviews occurred from September 6 through October 

 18, 2003. 



3.2.1.1.3 Water Regulatory Framework 



Montana Surface Water Quality Standards 



According to MCA 17.30.608 (1), this portion of the Middle Clark Fork 

 River basin (HUC 1701024) including the Fish Creek drainage and its 

 tributaries are all classified as B-1. Among other criteria for B-1 waters 

 no increases are allowed above naturally occurring levels of sediment and 

 minimal increases over natural turbidity. "Naturally occurring" as defined 

 by MCA 17.30.602 (17) includes conditions or materials present during 

 runoff from developed land where all reasonable land, soil, and water 

 conservation practices, commonly called BMP's, have been applied. 

 Reasonable practices include methods, measures, or practices that protect 

 present and reasonably anticipated beneficial uses. These practices 

 include but are not limited to stmctural and non-structural controls and 

 operation and maintenance procedures. Appropriate practices may be
