Dakin Creek - Determine Possible Impairment

Purpose

Dakin Creek is a 3.4 mile long cold-water stream that empties into Big Silver Lake. No data was found on the SWIMS database for this stream. Additionally, Regional staff have noted the following: - The land-use in the watershed is primarily agricultural. - Upper reaches are largely ditched and very wide. - Water quality appears poor with considerable sediment deposition.

Objective

Ted Johnson will conduct the following field work to determine if Dakin Creek should be placed on the 303(d) list of impaired waters. 1. Fish assessment conducted once in the two year project. 2. Total Phosphorus (monthly: April 1st – October 31st). 3. Habitat assessment conducted once in the two year project. 4. Stream-bank erosion assessment conducted once in the two year project. 5. Normal sampling parameters (transparency, DO, pH). 6. Temperature monitoring for two years (3 tidbits)

Outcome

This level of effort should be sufficient to determine if this stream should be considered impaired and placed on the 303(d) list following the two year assessment.
