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)	This Schedule 13D/A is being filed on behalf of Thomas P. 
Clark ("T Clark"), and by TPC Ventures, LLC (the "LLC"), 
Ryan T. Clark ("R Clark") and Thomas P. Clark Annuity Trust 
u/a/d April 29, 2005 (the "Trust") (collectively T Clark, R 
Clark, the LLC and the Trust are referred to as the 
"Reporting Persons"). T Clark passed away on June 14, 2005, 
therefore this is the final filing for T Clark.

(b)	The principal business address for the Reporting Persons is 
the address for the Company's executive offices as listed 
above.

(c)	At his death, T Clark was retired. T Clark was formerly the 
CEO of the Company and remained an employee of the Company 
until his death. R Clark is self-employed. The LLC is 
incorporated in the State of Colorado. The principal 
business address for the Reporting Persons is the same as 
the principal executive offices of the Company as listed 
above.  

(d) (e)	During the last five years, none of the Reporting Persons 
have been convicted in any criminal proceedings (excluding 
traffic violations or similar misdemeanors) nor have the 
Reporting Persons been a party to any civil proceedings 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)  	T Clark and R Clark are citizens of the United States of 
America.

Item 3.	Source and Amount of Funds or Other Consideration

Not applicable


Item 4.	Purpose of Transaction

Upon T Clark's death, 150,000 shares of Common Stock directly 
owned by T Clark were transferred to the Thomas P. Clark Trust 
dated November 9, 2004 (the "TC Trust").  These shares will be 
distributed to the beneficiaries in accordance with the TC Trust 
terms.  The Trustee of the TC Trust is R Clark.  

The LLC's direct beneficial ownership of 2,049,705 shares, 
remains unchanged from the Schedule 13D/A filed with the 
Commission on May 13, 2005, except that the .1% direct ownership 
interest by T Clark in the LLC is now owned by the estate of T 
Clark, of which R Clark is the personal representative.  Upon T 
Clark's death, R Clark became the manager of the LLC.  As 
manager, R Clark has sole voting and distributive power over the 
2,049,705 shares of Common Stock directly owned by the LLC.

Except as described below, the Reporting Persons have 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, the Reporting Persons reserve 
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") T Clark had 
agreed, along with other parties, to vote the shares of the 
Common Stock, owned or controlled by him, 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. The Common Stock directly held 
by the LLC, which was transferred from T Clark as more fully 
described in the Schedule 13D/A filed with the Commission on May 
13, 2005, will continue to be subject to the 1992 Voting 
Agreement. EP Fund owns 447,302 shares of common stock of the 
Company or 3.2% 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 1,518,515 
shares of common stock or 10.8% 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)	As of July 5, 2005, the LLC is the direct beneficial owner 
of 2,049,705 shares of Common Stock, or 14.6% of the 
outstanding Common Stock of the Company.  Upon T Clark's 
death, R Clark became the manager of the LLC.    

The Trust, due to its majority ownership of the LLC, and R 
Clark as sole trustee of the Trust and as manager of the 
LLC, may be deemed to have indirect beneficial ownership of 
the 2,049,705 shares (14.6% of the total outstanding common 
stock) owned by the LLC.  

R Clark, as sole trustee of the TC Trust, may be deemed to 
have an indirect beneficial ownership of 150,000 shares 
(1.1%) of Common Stock, held by the TC Trust.  R Clark has 
no pecuniary interest in these shares.  R Clark, as the 
personal representative of the estate of T Clark, has an 
indirect beneficial ownership of 19,500 shares (less than 
1%) of Common Stock in the estate of T Clark. 

R Clark and the Trust disclaim beneficial ownership of all 
shares of common stock owned by, and disclaim the existence 
of a "group" within the meaning of Section 13(d)(3) of the 
Securities Exchange Act of 1934 with, the other parties to 
the 1992 Voting Agreement.

(b)	R Clark has the sole power to dispose of and vote (i) 
2,049,705 shares of Common Stock owned by the LLC, (ii) 
150,000 shares of Common Stock owned by the TC Trust, and 
(iii) 19,500 shares of Common Stock held by the estate of T 
Clark, all of which are subject to the 1992 Voting 
Agreement.  

(c)	None

(d)	None

(e)	T Clark ceased to be the direct beneficial owner of more 
than five percent of the outstanding common stock on June 
14, 2005.

Relationships with Respect to Securities of the Issuer
