SURFACE WATER MONITORING <br />Monthly surface water samplings for flow were conducted at each of <br />the three stations located on Stollsteimer Creek during the third week of each <br />month. Quarterly water quality samples were collected during the first month of <br />each quarter (January, April, July, October). Flow data was also collected at <br />Station DC-1 on Deep Creek (tributary of Stollsteimer Creek) on a weekly basis <br />during flow conditions. <br />Methods <br />During monthly visits to each station, flow measurements were made <br />using aTeledyne-Gurley Model 622 current meter. Measurements were made by <br />stretching a 100 foot tape across a surveyed cross-section of the creek and <br />utilizing the USGS six-tenths depth method. In the office, cross-sections were <br />drawn to assess changes in stream bed configuration and flows were calculated. <br />During quarterly samplings for water quality, measurements for <br />temperature, pH and conductivity were made utilizing an Orion Research Model <br />399A portable pH meter and Hach Model 16300 portable conductivity meter. All <br />other parameters were collected in precharged bottles and submitted to Bookcliffs <br />Laboratory in Steamboat Springs for analyses. Methods of analysis were consistent <br />with EPA standard testing procedures. <br />Results <br />Results of all surface water measurements made during 1985 are <br />contained in Appendix 1. A summary of major chemical parameters and flow is <br />presented in Table 1. <br />Flow data collected at the three surface stations on Stollsteimer Creek <br />indicates a range of 6.07 to 194.9 efs during the months of November and March, <br />respectively. High flows recorded during March and April were the result of <br />5 <br />
