The float became frozen in <br />the stilling well about November 27. The recorder functioned <br />properly throughout this quarter and all records are considered <br />good up to the time of the freeze up. <br />Lower Dry Fork Minnesota Creek <br />After the flow was cut back from Minnesota reservoir last quarter, <br />flow has remained constant. On about October 11, vandals tampered <br />with the pen of the recorder, causing a lose of data for this <br />period. Then on December 23, vandals struck again. This time <br />using a large caliber weapon, they put at least two rounds <br />through the instrument house and recorder. Anew recorder will be <br />needed at this site, as well as the possibility of armor plate. <br />When the unit was not being affected by vandals, the recorder <br />functioned properly and resulting records were considered good. <br />-B1- <br />
