Hale Creek upstream of Interstate 280. Hale Creek terminates at its confluence with Permanente Creek at Mountain View Avenue in Mountain View just west of St. Joseph School and south of McKelvey Park. Hale Creek is part of the Santa Clara Valley Water District's (SCVWD) Permanente Creek Flood Protection Project which aims to install overflow basins along Hale and Permanente Creeks to catch one hundred year flood waters in order to protect 1,664 parcels (1,378 homes, 160 businesses and 4 schools/institutions) downstream of El Camino Real (saving potential damages in excess of $47.9 million) and prevent flooding of Middlefield Road and Central Expressway, by 12/30/2016 and also to identify opportunities for environmental enhancement such as stream restoration, as well as trails, parks, and open space. From its confluence with Permanente Creek upstream to Rose/Rosita Avenue, the channel has been set in a straight concrete channel to move storm flows - at Marilyn Drive it is dated 1952 and at Arboleda Drive it is dated 1960. The concrete sides transition smoothly from rectangle to trapezoid just over 30 feet north of Arboleda Drive. However the SCVWD in 2012 proposed widening and/or deepening this concrete channel. Ecology A fish distribution study found no Steelhead Trout (Oncorhynchus mykiss) at two locations sampled in August 1981. However, the fact that Hale Creek is tributary to a historic trout stream (Permanente Creek) suggests that steelhead may have used the stream.
