Item 1.	Security and Issuer

This Schedule 13D/A is filed with respect to shares of Common 
Stock, par value 1/3 of $.01 ("Common Stock"), of Pure Cycle 
Corporation, a Delaware Corporation (the "Company").  The 
Company's principal executive offices are located at 8451 
Delaware Street, Thornton, CO 80260.

Item 2.	Identity and Background

(a), (b) and (c).  This Schedule 13D/A is being filed by Thomas 
P. Clark ("Clark"), whose business address is 8451 Delaware 
Street, Thornton, CO 80260.  Clark is retired but was formerly 
the CEO of the Company and remains an employee of the Company 
whose principal address is listed above.

(d) and (e).  During the last five years Clark has not been 
convicted in a criminal proceeding (excluding traffic violations 
or similar misdemeanors) or was Clark a party to a civil 
proceeding of a judicial or administrative body of competent 
jurisdiction and as a result of such proceeding was or is 
subject to a judgment, decree or final order enjoining future 
violations of, or prohibiting or mandating activities subject 
to, federal or state securities laws or finding any violation 
with respect to such laws.

(f)   Clark is a citizen of the United States of America.

Item 3.	Source and Amount of Funds or Other Consideration

Not applicable

Item 4.	Purpose of Transaction

Clark sold 130,000 shares of Common Stock for $7.25 per share 
for financial reasons.

Except as described below, Clark has no present plans or 
proposals that relate to or would result in any transaction of 
the kind described in paragraphs (a) through (j) of Item 4. In 
the future, however, Clark reserves the right to adopt such 
plans or proposals, subject to applicable regulatory 
requirements, if any.

Pursuant to an Amended and Restated Voting Agreement dated 
August 12, 1992, a copy of which was filed previously as Exhibit 
A to Amendment No. 1 (the "1992 Voting Agreement") Clark has 
agreed, along with other parties, to vote his shares of the 
Company's Common Stock in favor of electing a representative 
designated by The Environmental Private Equity Fund II, L.P., a 
Delaware limited partnership ("EP Fund"), to the Company's Board 
of Directors. EP Fund owns 478,352 shares of Common Stock of the 
Company or 3.5% of the total outstanding Common Stock. Companies 
affiliated with EP Fund who are parties to the 1992 Voting 
Agreement (the "EP Fund Entities") own an additional 1,632,572 
shares of Common Stock or 11.9% of the total outstanding Common 
Stock. George W. Middlemas currently serves on the Board and was 
elected as the EP Fund representative.

Item 5.	Interest in Securities of the Issuer

(a)   Clark owns 2,310,206 shares of Common Stock which is 
approximately 16.9% of the outstanding Common Stock of the 
Company.

Although Clark is a party to a voting agreement more 
specifically described in Item 4, Clark disclaims 
beneficial ownership of all shares of Common Stock owned by 
the other parties to that agreement and disclaims the 
existence of a "group" within the meaning of Section 
13(d)(3) of the Securities Exchange Act of 1934.

(b)   Clark has sole power to dispose of 2,310,206 shares of 
Common Stock, subject to the 1992 Voting Agreement, which 
requires Clark to obtain consent for disposition unless the 
transferee agrees to be bound by the 1992 Voting Agreement 
or the disposition is pursuant to an agreement in effect on 
August 12, 1992.  Subject to the terms of the 1992 Voting 
Agreement, Clark has the sole power to vote 2,140,206 
shares of Common Stock.

(c)   Effective August 31, 2004 the Company entered into a 
Settlement Agreement with LCH, see the Company's Annual 
Report on Form 10-KSB for the year ended August 31, 2004. 
Under the Settlement Agreement, LCH, the Company and Clark, 
the Company's former CEO, reached agreement on the 
satisfaction of the Company's obligations (i) to repay 
$950,000 principal amount of promissory notes and 
$1,557,110 of accrued interest and (ii) to pay $4.0 million 
of contingent obligations to LCH. In the Settlement 
Agreement, (i) the Company made a $950,000 cash payment and 
(ii) Clark surrendered 306,279 shares of Common Stock to 
the Pledgee which had been pledged as collateral to secure 
payment of the notes. In response to a claim made by Clark 
against the Company to be made whole, on January 13, 2005, 
the Company paid Clark $50,555 in cash and issued to him 
300,000 shares of restricted Common Stock.

On February 2, 2005 Clark sold 130,000 shares of Common 
Stock for $7.25 per share.
