The geologic, geomorphic, and hydrologic context underlying options for long-term management of the Spirit Lake outlet near Mount St. Helens, Washington.

The 1980 eruption of Mount St. Helens produced a massive landslide and consequent pyroclastic currents, deposits of which blocked the outlet to Spirit Lake. Without an outlet, the lake began to rise, threatening a breaching of the blockage and release of a massive volume of water. To mitigate the hazard posed by the rising lake and provide an outlet, in 1984–1985 the U.S. Army Corps of Engineers bored a 2.6-km (8,500-ft) long tunnel through a bedrock ridge on the western edge of the lake.

Lensing: Leadership on education funding, mental health and accessible voting

Serving as state representative of House District 85 for the past few years has been a privilege and an honor. I have worked hard to stand for the people of my district fighting for issues that are important to them and to the voters of Iowa City. I want to continue that advocacy and am running for another term in the Iowa House and ask for your vote.

I vigorously support adequate funding for education from pre-school to our community colleges and universities. Our young people are Iowa’s future and deserve the best start available through our excellent education system in Iowa. But we need to provide the dollars necessary to keep our teachers in the classroom so our children are prepared for whatever may lie ahead of them.

I have advocated for the fair treatment of workers in Iowa and support their right to organize. I have worked on laws for equal pay for equal work and whistle blower protection.

I am for essential funding for mental health services for Iowans of all ages. Children and adults who are struggling with mental health issues should have services available to them no matter where they live in this state.

I have fought to keep government open and accessible to Iowans. I support open records and open meetings laws to ensure that availability and transparency to all Iowans.

Keeping voting easy and accessible to voters has been a priority of mine. I support a fair and balanced redistricting system for voting in Iowa.

I have advocated to keep the bottle deposit law in place and expand it to cover the many new types of containers available.

I have worked on oversight legislation after several investigations into defrauding government which involved boarding homes, government agencies and pharmacy benefit managers (the “middleman” between pharmacies/Medicaid and the healthcare insurance companies.)

I cannot avoid mentioning the challenge of the coronavirus in Iowa. It has impacted our health, jobs, families and businesses. No one could have predicted this pandemic but as Iowans, we need to do our best to limit contact and the spread of this disease. My sincere appreciation goes to those workers on the frontlines of this crisis: the healthcare workers, store owners, businesses, farmers, teachers and workers who show up every day to keep this state moving forward. Thank you all!

There is still much work to be done to keep Iowa the great place where we live, work and raise our families. I am asking for your vote to allow me the privilege of continuing that work.

Vicki Lensing is a candidate in the Democratic primary for Iowa House District 85.
