Land development in the Lower Mainland is governed by five Regional Districts which develop land use plans through zoning by-laws. Scaled map inventory of zoning in each watershed permits linear measurement of riparian land use and rating of stream enhancement potential by extent and type of land development: (1) Excellent enhancement potential : 7 streams with 75-100% stream length in conserved riparian land use, (2) Good enhancement potential: 7 streams with 50-75% stream length in conserved riparian land use, (3) Moderate enhancement potential: 5 streams with 60-100% stream length in residential, conserved and undeveloped use, (4) Low enhancement potential: 18 streams with 60-100% stream length in agriculture and conserved land use, and (5) Very low enhancement potential: 3 streams with 35-100% stream length in industrial use. Comparison of amounts of recorded water to known discharges shows some streams are over-recorded during periods of extreme low flow. Fish enhancement potential is affected by water r
