Module 2 Bechmark Location, Cross-sectional Survey, Stream Discharge

Stream Name: MACKAY CREEK Survey Date: 2014-08-26
Organization Name: PSKF Project Name: ISMPMackay
Stream Segment #: 1 Stream Section #: 1
Data entered by: PM Survey ID: 40

Step 1. Benchmark Location

Directions to Benchmark: In Heywood Park - on right bank measure 9.7m north of hatchery chainlink fence and head into creek we took more cross sectional measurements then room to post all measurements were used when determining depth, area etc

Step 2. Cross-Sectional Survey

Location relative to benchmark: at Photos Taken? yes
Bankfull Channel Width: 8.50 Average Bankfull Depth: 25.42
Wetted Channel Width: 6.20 Average Wetted Depth: 9.89
Measurements taken every 0.50 metres Number of measurements taken: 14

First and Last Measurements Taken .1m from the streambank edge
