My friend Lynn, who lives up north in Chico, asked about the ponding basins I wrote about in my last post. She had not heard of these before. I don’t think Chico has a flooding problem, nor is it located in a deep flat valley with hardpan soil as its underpinning.
Fresno has these issues, and for decades had severe flooding within the city. My husband has a photo in his 1967 yearbook of boats being used for transportation on one of the main thoroughfares after a series of rain storms had pelted the San Joaquin Valley.
Fresno had sense enough to start a drainage system that diverted rainwater from city streets into ponding basins and then used the water to recharge the city’s water pumps, utilizing all that rain later in the year when we would be in drought status.
Some of the 150 ponding basins within the city are wildlife refuges, like this one behind our housing tract:
Others are kept filled all year for recharging purposes. And still others are used as playgrounds, ball fields, and dog parks when the water recedes in summer and fall. Right now the city is diverting the water from overflowing basins into canals that will take the water out to the San Joaquin River and it will eventually make its way to the Pacific Ocean.
Unfortunately, other areas in the Valley are not as fortunate to have this flood control, and right now many smaller communities are battling water and mud. Yesterday, a small school in the south part of the valley was flooded with rainwater that had no where else to go except through the school’s hallways.
