Project Description

The project consists of constructing an inlet spillway located on the north side of Walnut Avenue and leading into the 37 AF basin through an energy dissipater. The 37 AF basin will then discharge the collected storm water through a low flow outlet and storm drain connecting to the existing 120” storm drain located north of Main Street. The Walnut Avenue basin is designed to allow a relatively large flow of storm water to enter and be a discharged in a controlled manner by an outlet structure in the event of a large storm. The basin system will reduce sediment transport to the Mojave River and eliminate flooding along Walnut Avenue and Main Street.

Project Description
The Ponds would provide groundwater recharge upgradient from Hesperia Water District wells. The Hesperia Master Plan of Drainage identifies a 65 acre site for a storm water detention basin in the Antelope Valley Wash south of the newly constructed Ranchero Road. In addition to storm water detention, the site would be able to accommodate groundwater recharge. Integrates Projects 4 and 109.

The Basin would provide groundwater recharge upgradient from Hesperia Water District wells. The Hesperia Master Plan of Drainage identifies a 120 acre site for a storm water detention basin at the east end of Cedar Street and southwesterly of the California Aqueduct. In addition to storm water detention, the site would be able to accommodate groundwater recharge. Integrates Projects 14 and 107.

Project Description
Although extremely variable, on average 41,000 AFY of storm water flows out of Afton Canyon every 6 years. Based on current State Water Project delivery costs this equates to approximately $16 million worth of “lost” water flowing out of the region to unpopulated areas and desert playas. The project proposes infrastructure that could capture a significant portion of this water and allow it to recharge area groundwater systems. This could be accomplished through various diversion structures along the river or make use of the existing Forks Dam to impound storm water. Impounded storm water could be slowly released from the Forks Dam at a rate that would allow percolation rather than run-off though Afton Canyon.

Project Description
The Sheep Creek Wash Storm Water Retention project is intended minimize storm water damage. This conceptual plan would require diverting storm water flows from Sheep Creek Wash to a proposed detention basin. Storm water flows would be monitored at the inlet of the basin. A proposed monitoring well will also be used to monitor static levels.

Project Description
Project to capture runoff from the San Bernardino Mountains in the Lucerne Valley Subbasin. Currently, large storm flows drain to dry lake beds in the area that have low percolation rates. Consequently, the majority of water that drains to the lake beds is lost to evaporation and never enters the basin. The project would divert storm flows to detention basins with high rates of percolation to decrease losses from evaporation. This project would capture water lost to evaporation rather than water that would flow downstream to other users in the Mojave Basin Area.
