Historic American Engineering Record: Old Crosscut Canal, North Side of Salt River, Maricopa County, Arizona

Historic American Engineering Record (HAER) No. AZ-21 presents a written historical summary and relevant historical documentation about the construction and use of the Old Crosscut Canal, which unified irrigation systems near Phoenix's urban core on the north side of the Salt River and contributed to flood control. The report contains a narrative description, photographs, drawings, and maps.

The Old Crosscut Canal stretched from approximately Indian School Road to south of Washington Street near 46th and 48th streets in Phoenix. Although it has been a part of the landscape since the late 1800's, it has not been used to carry irrigation waters since approximately 1906. The Salt River Project and other agencies did not maintain active interest in maintaining the feature, as it was used sporadically for flood control.

The Old Crosscut Canal was built in 1889 to connect the Arizona Canal (see http://core.tdar.org/document/393523) with Grand Canal (see http://core.tdar.org/document/393162) and other large canals on the north side of the Salt River. Then, in 1913, the New Crosscut Canal was constructed two miles to the east. It replaced the old canal. The Old Crosscut Canal was used in the 1920s to drain waterlogged farmlands south of the Arizona Canal. After years of intermittent use, in the 1970s, the Flood Control District of Maricopa county renovated the structure to serve as a flood control wasteway to the Salt River. The canal right-of-way was included in a bike path system and recreational use increased. Later, in 1989, the lower part of the canal was relocated to construct the East Papago-Hohokam freeway.

美国历史工程记录（Historic American Engineering Record, HAER）第AZ-21号收录了关于旧横切运河（Old Crosscut Canal）的书面历史概述与相关历史文献，该运河整合了盐河北岸凤凰城城区北侧的灌溉系统，并助力防洪工作。本报告包含叙事性描述、照片、图纸与地图。
旧横切运河的范围大致从印第安学校路（Indian School Road）延伸至凤凰城第46街与第48街附近的华盛顿街以南区域。尽管自19世纪末以来它便已是当地景观的组成部分，但自约1906年起便不再用于输送灌溉用水。盐河项目（Salt River Project）及其他机构并未积极维护该设施，因其仅被偶尔用于防洪。
旧横切运河始建于1889年，用于连接亚利桑那运河（Arizona Canal，详见http://core.tdar.org/document/393523）、格兰德运河（Grand Canal，详见http://core.tdar.org/document/393162）及盐河北岸的其他大型运河。1913年，在其东侧两英里处修建了新横切运河（New Crosscut Canal），取代了旧运河。20世纪20年代，旧横切运河被用于排干亚利桑那运河南侧受淹农田的积水。经过多年间歇性使用后，1970年代，马里科帕县防洪区对该设施进行翻新，将其改造为通往盐河的防洪泄洪道。该运河的用地被纳入自行车道系统，休闲使用需求也随之增加。1989年，为修建东帕帕戈-霍霍坎高速公路（East Papago-Hohokam Freeway），运河的下游段被改道迁移。
