A new bridge was built about one-fourth mile upstream from thesite of the old one. Measurements can be made from this bridgeonly when the canal is running full. Wading measurements are madeat a section about 300 feet downstream from the gage. There was flow in the canal on the single days for which gageheights are missing. During a few of the days when the canal wasat its highest, owing to the flood in Milk River, the water was wasted,but the greater part of the time from June 5 to 30 the water was usedfor irrigation. The head-gates were closed for the season September 22, 1907, andSeptember 23, 1908.
